The Importance of Overexcitation Protection for Generators and Generator Step-up Transformers
“Overexcitation of a generator or any transformers connected to the generator will occur whenever the ratio of the voltage to frequency (V/Hz) applied to the terminals of the equipment in excess of the machines rating. Overexcitation causes saturation of the magnetic core of the generator or connected transformers, and stray flux may be induced in non-laminated components that are not designed to carry flux. Excessive flux may also cause excessive eddy currents in the generator laminations that result in excessive voltages between laminations. This may cause severe overheating in the generator or transformer and eventual breakdown in insulation. The field current in the generator could also be excessive.” This paper will provide insight into the causes of overexcitation from both operations, and outside influences. We will also present information on industry standards on how to derive proper settings for overexcitation protective relaying, according to IEEE and NERC recommendations, and provide proper testing techniques to validate settings.

Bringing Safe Lithium-ion Battery Tech from Outer Space to Your Space
The growing popularity of energy storage systems has driven innovation in the industry for decades. Many of these storage systems utilize lithium-ion batteries, but there are limitations on how and where this technology can be applied due to safety concerns. While it’s common in rural areas without a dense population, urban areas are left with few energy storage options that meet state and city safety requirements. Now, technology is used to keep lithium-ion batteries safe in space is coming down to Earth to provide storage solutions for C&I, residential and medical uses. In partnership with KULR Tech Corp., Volta Energy found an innovative way to physically contain lithium-ion technology and make it safer to deploy. Its new class of battery packs virtually eliminates the thermal runaway risks associated with lithium-ion technology and is now being tested for use in what will be an industry-first: an indoor medical research facility located in New York State. The core design for Volta Energy’s new battery packs includes KULR’s HYDRA thermal runaway shield that was developed for NASA’s Mars 2020 Perseverance Rover and for transporting and storing lithium-ion batteries to the International Space Station – environments in which mitigating and containing lithium-ion battery cell propagation is critical to mission success. HYDRA absorbs heat and prevents cells from entering in thermal runaway propagation. Volta Energy uses this space technology to solve for point-of-use storage in and adjacent to occupied structures. The pack system is designed to be fully independent of any secondary systems, can be installed indoors or outdoors depending on the need, and can be configured in systems to provide up to 1 MW of storage. This architecture is the only design on the market that can be safely installed in nearly any environment or location. These packs have been field-tested for over ten years in some of the harshest industrial environments and extreme climates and have experienced numerous generation changes that addressed early design failures. This discussion will feature the extensive field test results at real-world sites in New York State and discuss how Volta was able to pass the stringent state building codes to be approved for an indoor installation using lithium-ion technology. It will also feature insights from KULR about the down-to-Earth applications for its technology.

Cost Reduction Roadmap for VPPs and Related DER Aggregation Programs
Technological innovations are driving the widespread deployment of solar plus storage (solar plus) and controllable loads. Coordinated deployment of these technologies can provide a variety of grid services including load, voltage, and frequency management. Maximizing the value of solar plus entails coordinating or orchestrating various load and output shifts through some type of centralized energy management system. A growing body of literature demonstrates the potential technical and economic value of solar plus but data-driven studies based on deployed solar plus systems are lacking. NREL has conducted an analysis of real-world data from the 3,000 solar plus homes at the Jasper Valley project in Arizona. NREL assessed the impacts of consumer behavior, home architecture, and rate design on the value delivered by solar plus homes to the distribution grid including infrastructure deferral. These real-world data were then leveraged to identify a cost reduction roadmap for similar virtual power plants (VPPs) or distributed energy resource (DER) aggregation programs to maximize deployment nationwide. In this presentation, NREL will explain how utilities can better model the impact of similar new construction projects that can reduce infrastructure requirements while providing new resources to help increase the flexibility of the distribution grid. NREL will identify opportunities and barriers to maximizing the use of VPPs nationwide and will conclude with best practices for maximizing solar plus homes benefits to the electrical grid.

Preparing for Energy Markets with Automated Optimization of Customer Energy Assets
In the Commercial and Industrial sector, distributed energy resources (DERs) have become increasingly pervasive, driven in part by available market revenue streams and accelerated by falling hardware prices for storage and renewable generation, available incentives, and increasingly sophisticated financing offerings. However, up until now participation in markets has largely been executed through singularly-directed or static strategies. For example, DER project owners and operators that only participate in capacity programs, which require load reduction commitments ahead of time, often leave value on the table. The next phase of a reliable and clean energy mix will not necessarily center around more DERs but around the better use of DERs. Millie Knowlton, Senior Manager of Strategy and Business Development at CPower Energy Management, will present on how to look across the entire continuum of energy value from both grid service programs and on-bill savings programs. Knowlton will share data from customer case studies over the past six months in PJM that leverage artificial intelligence-based optimization of on-site assets to illustrate the incremental value that can be captured when energy value streams are optimized. The presentation will educate on how to move underutilized assets further along the energy value continuum to participate in more services and value streams. Knowlton will cover market and energy programs that couple well together, depending on each asset type. Additionally, by leveraging automated optimization, project owners can better align the incentives of on-site improvements for greater returns from market participation. To help the audience determine the maximized value potential of their assets, the presentation will leverage CPower’s experience working with over 11,000 customer sites and across all types of assets from traditional back-up generators to energy storage. It will use case studies to illustrate the necessary components to scheduling, bidding, and dispatching assets on an ongoing basis, including the hardware, software, operational and compliance requirements. For site owners and third-party project owners or operators to earn the maximum value potential from DERs, they will need to be able to seamlessly balance priorities and make decisions based on changing information. Only then can DERs fully contribute to a more resilient grid.

Optimizing Plant Operation & Maintenance Using Remote Presence Technology – Going Beyond Monitoring
Fleet-level monitoring, especially for major critical assets like gas turbines, is well established and it has proven to improve power plant reliability and performance. But technologies are becoming available that go far beyond just monitoring, such as advanced analytics, interactive software, and the ability to capture and broadly apply SME (Subject Matter Expert) expertise. In this age of asset digitalization, when on-site SME experience is becoming increasingly difficult to sustain, power plants of the future will be more autonomous and benefit from remote support. As the data streams increase, so do the capabilities, and it is imperative to take a total plant approach. Through targeting critical assets across the entire power plant and comparing their data outputs against advanced analytic models, outlier data points initiate the generation of an automated notification highlighting any potential operational risks. These notifications pinpoint the specific location of any equipment of concern, gauge its overall health and life consumption, and provide a recommended course of action to mitigate. Advanced speech recognition technologies, similar to Alexa or Google Home, enable human like conversation with the power plant assets, as well as beyond. Total plant data is collected, analyzed, trended, contextualized, and made available 24/7. Automated notifications flow through this interactive platform, integrating them with live KPI data and documentation such as O&M manuals, past outage reports, etc. Virtual presence technologies add the capability to assist with onsite troubleshooting from anywhere in the world through the use of mixed reality headsets, giving the on-site power plant teams an extensive toolbox of expert support to keep their plant running optimally. These new technologies go far beyond traditional monitoring and are already being applied at pilot plants. This paper is based on case studies highlighting the results from those pilot plants.

Best Practices for Structuring and Negotiating EPC Contracts for Renewable Power Power Projects
This discussion will comprise an overview, from the owner’s/developer’s perspective, of two fundamental contracts for building a renewable (wind or solar) electric generation facility: the Equipment Procurement Agreement (EPA) and the balance of plant (BOP) Engineering Procurement and Construction Agreement (EPC). The first half will focus on key provisions that should be in the typical EPA, outlining the key issues and risks inherent in these documents and focusing on how to protect the owner’s/developer’s interests at every step. The presenters will delve into “best practices” and “critical nuances” on key subjects, including in such areas as payment and payment security structures, equipment delivery obligations, performance testing and guarantees, and warranties. The second half will focus on the typical BOP EPC Agreement, focusing on how the three fundamentals of scope, time and money are each addressed throughout the document’s inter-woven provisions, and how various key risks can impact these fundamentals. The panelists will delve into “best practices” and “critical nuances” on key subjects, including in such areas as payment and payment security structures, equipment delivery obligations, performance testing and guarantees, and warranties. Change Order, Force Majeure. Finally, the panelists will explore strategic techniques for “weaving” the EPA and BOP EPC together so as to replicate near-turn-key risk allocation in the multi-prime contracting situation. Such an approach can help decrease a project’s construction risk, helping to prime it for project financing

Dynamic Security Optimization for N-1 Secure Operation of Power Systems with 100% Inverter-based Generation: First Experiences from Hawaii Island
Reliable power system operation with 100% inverter-based renewable generation is an unsolved and challenging problem. The main reason is that today’s power systems require that at least 25% of the load is supplied by synchronous generators at any time, e.g., gas turbines, steam turbines, or diesel generators, as documented in studies for Hawaii and Ireland. One of the most challenging factors for achieving reliable operation with 100% inverter-based renewable generation is power system stability after N-1 contingencies. This roadblock for high renewable generation can be overcome using Dynamic Security Optimization (DSO) technology for tuning controller parameters of generation units in order to improve the dynamic security of the power system. This presentation will provide an overview of the developed technology and first results from the U.S. Department of Energy ARPA-E funded project with Hawaiian Electric’s, Hawai`i Island Service Territory (HECO), OPAL-RT, and PNNL. The Dynamic Security Optimization technology is unique because it allows, for the first time, reliable power system operation with 100% inverter-based renewable generation in a transmission system.
