Design of an Open Smart Energy Gateway for Smart Meter Data Management

With the widespread deployment of electronic interval meters, commonly known as smart meters, came the promise of real-time data on electric energy consumption. Recognizing an opportunity to provide consumers access to their near real-time energy consumption data directly from their installed smart meter, we designed a mechanism for capturing those data for consumer use via an open smart energy gateway (OpenSEG). By design, OpenSEG provides a clearly defined boundary for equipment and data ownership. OpenSEG is an open-source data management platform to enable better data management of smart meter data. Effectively, it is an information architecture designed to work with the ZigBee Smart Energy Profile 1.x (SEP 1.x). It was specifically designed to reduce cyber-security risks and provide secure information directly from smart meters to consumers in near real time, using display devices already owned by the consumers. OpenSEG stores 48 hours of recent consumption data in a circular cache using a format consistent with commonly available archived (not real-time) consumption data such as Green Button, which is based on the Energy Services Provider Interface (ESPI) data standard. It consists of a common XML format for energy usage information and a data exchange protocol to facilitate automated data transfer upon utility customer authorization. Included in the design is an application program interface by which users can acquire data from OpenSEG for further post processing. A sample data display application is included in the initial software product. The data display application demonstrates that OpenSEG can help electricity use data to be retrieved from a smart meter and ported to a wide variety of user-owned devices such as cell phones or a user-selected database. This system can be used for homes, multi-family buildings, or small commercial buildings in California.

15 MW HArdware-in-the-loop Grid Simulation Project

The 15MW Hardware-in-the-loop (HIL) Grid Simulator project was to (1) design, (2) construct and (3) commission a state-of-the-art grid integration testing facility for testing of multi-megawatt devices through a ‘shared facility’ model open to all innovators to promote the rapid introduction of new technology in the energy market to lower the cost of energy delivered. The 15 MW HIL Grid Simulator project now serves as the cornerstone of the Duke Energy Electric Grid Research, Innovation and Development (eGRID) Center. This project leveraged the 24 kV utility interconnection and electrical infrastructure of the US DOE EERE funded WTDTF project at the Clemson University Restoration Institute in North Charleston, SC. Additionally, the project has spurred interest from other technology sectors, including large PV inverter and energy storage testing and several leading edge research proposals dealing with smart grid technologies, grid modernization and grid cyber security. The key components of the project are the power amplifier units capable of providing up to 20MW of defined power to the research grid. The project has also developed a one of a kind solution to performing fault ride-through testing by combining a reactive divider network and a large power converter into a hybrid method. This unique hybrid method of performing fault ride-through analysis will allow for the research team at the eGRID Center to investigate the complex differences between the alternative methods of performing fault ride-through evaluations and will ultimately further the science behind this testing. With the final goal of being able to perform HIL experiments and demonstration projects, the eGRID team undertook a significant challenge with respect to developing a control system that is capable of communicating with several different pieces of equipment with different communication protocols in real-time. The eGRID team developed a custom fiber optical network that is based upon FPGA hardware that allows for communication between the key real-time interfaces and reduces the latency between these interfaces to acceptable levels for HIL experiments.

A Review of the American Recovery and Reinvestment Act Smart Grid Projects and Their Implications for China

The Chinese government has paid growing attention to renewable energy development and has set ambitious goals for carbon dioxide (CO2) emissions reduction and energy savings. Smart grid (SG) technologies have been regarded as emerging ways to integrate renewable energy and to help achieve these climate and energy goals. This report first reviews completed SG demonstrations under the U.S. American Recovery and Reinvestment Act (ARRA); especially two key programs: the SG Investment Grant (SGIG) and the SG Demonstration Project (SGDP). Under the SGIG, the larger of the two programs, over $3.4 billion was used to help industry deploy existing advanced SG technologies and tools to improve grid performance and reduce costs. Including industry investment, a total of $8 billion was spent on 99 cost-shared projects, which involved more than 200 participating electric utilities and other organizations. These projects aimed to modernize the electric grid, strengthen cyber security, improve interoperability, and collect comprehensive data on SG operations and benefits.

Pomona College Dreamers and Achievers Profile

As an undergraduate at Pomona, Carol Meyers ’00 enjoyed proofs and pure math, but she also had a hankering to solve real-world problems. This eventually led her to discover the field of operations research, in which she earned a PhD from MIT, and from there onto a career at a national laboratory. “National labs are great because they serve a role between academia and industry,” she says, “solving problems too large or too applied for academia, and insufficiently profitdriven for industry.” Her workplace, Lawrence Livermore National Laboratory, is home to the world’s largest laser, frequent home to the world’s fastest supercomputer, and the namesake to element 116 (Livermorium) on the periodic table. During her 10+ years at the laboratory Carol has worked in the areas of energy grid modernization, nuclear counterterrorism, cyber security, stockpile stewardship, and supercomputing, often as a consultant providing mathematical modeling and optimization expertise. Carol has two young kids and serves as co-chair of the New Moms’ Group at her workplace. “Being in a supportive community of moms has really helped me at work,” she says, “because let’s face it – moms know how to get things done!” “People talk a lot about the importance of networking, but this doesn’t have to mean starting technical discussions with strangers. The ability to bond with and relate to other people is far more important, and many women do this very well. Some of my best work networking connections have come through our employer-affiliated daycare.”

Implementation of ISO 50001 at Marine Corps Air Station Beaufort

The ISO 50001 implementation demonstration at U.S. Marine Corps Air Station (MCAS) Beaufort proved the feasibility of integrating an ISO 50001-conforming EnMS into existing command structures. The approach of leveraging external experts in gap analysis, EnMS training, and technical assistance were effective. In addition, strong leadership commitment and personnel resources were critical for success. Addressing typical personnel rotations by training newly rotated personnel and partnering key leadership positions in the EnMS structure with civilian counterparts can ensure program continuity. The project team brought forward many creative solutions that address the unique challenges for the Marine Corps and has paved the way for future Marine Corps EnMS implementations with example strategies and work products. Implementation of an ISO 50001 EnMS at additional Marine Corps facilities could provide for integration of base energy-related data systems and standardized energy reporting, using meaningful metrics for energy performance improvement. Beyond the energy performance improvement benefits of ISO 50001, widespread adoption of the standard at Marine Corps facilities would provide the communication and integration basis on which to reduce energy resiliency concern and could integrate energy service cyber security protections base wide. High levels of energy consumption, aggressive mandates from multiple sources, complex organizational structures, and constant personnel rotation make ISO 50001 a uniquely attractive proposition for the Marine Corps in support of the DoD’s overall energy strategy. The recently launched Energy Ethos and Unit Energy Manager (UEM) programs offer dynamic action-based programs over which ISO 50001 based business management can provide integrated governance of the Marine Corps installations’ energy programs.

Licensing Challenges Associated with Autonomous Control

Very small special purpose reactors (SPRs), or microreactors at less than 50 MW electric, are under consideration by various entities for applications in remote installations and communities. These entities include remote municipalities, the US Department of Defense (DoD), and the US Department of Energy (DOE). SPRs or microreactors may be transportable from a factory with fresh fuel included to serve as a complete power battery. This type of plug-and-go resource requires inherently positive safety attributes and robust design. SPRs and microreactors are being designed to fulfill black-start or microgrid capabilities and to provide protection against severe natural phenomena or cyber security threats. These reactors would be available to operate for several years without a need to shut down for refueling.

Selection of Ten (10) Cybersecurity Scenarios For Project Cybersecure Interconnection of Distributed Energy Resources

Utilities use state-of-the-art tools for reliable integration of Distributed Energy Resources (DER) within the power grid. These tools evaluate how power grid operations might be affected by various DER integration scenarios, and help the utility develop strategies to ensure reliability and safety of the power grid. These tools were developed in response to rapid wide-scale DER deployment, and are now in common use to aid the process of operating a grid with high penetration of DER. As power system technologies continually advance, these tools must also be advanced to assist the development of cyber-secure architectures for the new communication and control pathways that are being introduced with technologies such as smart inverters and local storage control.

Advanced Sensors and Instrumentation (ASI) Program Plan. Nuclear Energy Enabling Technologies (NEET)

The U.S. Department of Energy Office of Nuclear Energy (DOE-NE) sponsors a crosscutting technology development (CTD) program addressing common instrumentation & controls (I&C) needs in all DOE-NE sponsored programs. In 2012, DOE-NE initiated the Nuclear Energy Enabling Technology (NEET) Program to conduct research, development, and demonstration (RD&D) in crosscutting technologies that directly support and enable the development of existing, new and advanced reactor designs, and fuel cycle technologies. These technologies will advance the state of nuclear technology, improve its competitiveness, and promote continued contribution to meeting our Nation’s energy and environmental challenges. The NEET Program has spurred innovation in the field of sensors and instrumentation, advanced methods for manufacturing, and cyber security. The Advanced Sensors and Instrumentation (ASI) program is one element of the NEET CTD that has spurred innovation in the measurement science field by funding research on sensors, instrumentation and controls, communication, and advanced analytics that measure system parameters, gauge component control input, and provide power plant owners and operators critical awareness so they can plan and safely manage operational evolutions. The NEET ASI Program has carried out research and development (R&D) required to develop and deploy innovative and advanced sensors, and instrumentation and control capabilities for current and future nuclear energy systems, and to enable the advanced technologies essential to NE’s R&D efforts needed to realize mission goals. The concept of technology readiness assessment is helpful for the classification of instrumentation technology as part of the program strategy. A technology readiness assessment evaluates technology maturity using the Technology Readiness Level (TRL) scale and was pioneered by the National Aeronautics and Space Administration in the 1980s for space technology. It has recently been adopted to advance fuels and materials. The NEET ASI program objective is to mature instruments technology to TRL 6, which is “demonstration of the technology in relevant environment.” While there may be instances in which a different strategy is justified, the aim of the program is to respond to DOE program and stakeholder needs for nuclear instrumentation then hand off the technology after demonstration for integration in a more complex system, for example an irradiation test, experimental loop or a plant component such as the core, primary system or heat exchanger. A mechanism to continue some level of support from NEET ASI during and after the adoption (for example, to maintain fabrication and calibration capabilities) will be defined as the first example of technology hand off comes to fruition. In addition, several paths exist within DOE to complement NEET ASI activities to extend the maturity beyond TRL, for example through GAIN, technology commercialization funding, and small-business programs. Role of NEET ASI CINR projects in the TRL space, and integration with direct funded demonstration.

Agent-Based Coordination Scheme for PV Integration (ABC4PV)

Renewables and especially photovoltaics (PV) have benefitted significantly from a host of incentives and policies targeted toward enhanced integration and adoption of specific energy technologies. However, with the push to move forward into a subsidy-free market framework, behind-the-meter residential PV applications have generally struggled to retain their value (unlike utility scale and commercial projects) [1]. This project focused on developing control-theoretic solutions aimed at improving the integration and interaction of behind-the-meter residential PV with other distribution system assets (controllable and non-controllable) to enhance the integrated value of residential PV. To this end, a suite of decentralized control methodologies have been developed to enable effective coordination and control of behind-the-meter residential load customers’ PV, battery storage systems (BSS), controllable loads and other similar assets within a distribution feeder. This interaction aims at procuring energy savings and, thus, energy bill savings. The main source of savings is drawn from reducing the effect of demand charge pricing and is realized at the feeder level, assuming community level interaction and management among the aforementioned assets. Optimal control of the assets is implemented with a distributed optimization methodology, leveraging consensus-based algorithms. The results gathered from the optimal control simulations demonstrates that the savings can be duly achieved and the algorithm decision times (to dynamically control asset set points, for example) are fast. As for the overall efficiency of PV+BSS systems, to procure energy savings from curtailment of the demand charge pricing effects, the optimal control is set up so as to minimize the variance of the load for all customers, throughout a feeder and throughout time in a rolling horizon scheduling with model predictive control. The control takes into account inter-temporal electrochemical storage (battery) degradation costs: specifically, we have developed a long-term lifetime model for the BSS that weighs in the effect of the degradation factor in the dispatch formulations, thus, a considerable operating cost that affects energy decision making. The levelized cost of energy (LCOE – redefined for the purpose of quantifying asset integration effectiveness through the customers’ energy cost) is shown to be below the threshold set for the combined PV+BSS topology of $ 0.14/kWh for multiple cases of PV penetration all the way up to 50%, provided that a policy of shared ownership of and savings is in place. Further, the LCOE calculated for the case before the deployment PV+BSS systems is also achievable, i.e. the deployment of PV+BSS, if planned and scheduled optimally. will have no effect on customers’ energy costs. From the control methodology viewpoint, the developed consensus-based algorithms are shown to converge for a wide range of problem cases (spanning normal operating scenarios and contingencies), guaranteeing dispatch solutions under forecasting errors, communication break-downs and cyber-security attacks. The proposed control solutions are scalable and real-time implementable, with dispatch computations and device set-point updates converging in less than 2s in most practical instances of the above events.

A Cybersecurity Event Simulation Tool and Platform

Digital Instrumentation and Control Systems (ICSs) have replaced analog control systems in nuclear power plants raising cybersecurity concerns. To study and understand the cybersecurity risks of nuclear power plants both high fidelity models of the plant physics and controllers must be created, and a framework to test and evaluate cyber security events must be established. A testing and evaluation framework of cybersecurity events consists of a method of interfering with control systems, a simulation of the plant network, and a network packet capture and recording tool. Sandia National Labs (SNL) in collaboration with the University of New Mexico’s Institute for Space and Nuclear Power Studies (UNM-ISNPS) is developing such a cybersecurity testing framework.
