초록/해제  
요약Distributed energy resources (DERs) like roof-top solar, electric vehicles, and flexible loads, have emerged as promising solutions to both decarbonize and democratize the energy sector. Without the proper technical and socioeconomic tools, DERs will not only fail to achieve these goals, but they will also leave the grid less reliable and less resilient than it is today. This thesis explores methods for leveraging DERs to enhance grid reliability, resiliency, and equity. Grid reliability ensures the adequate and stable supply of electricity to meet demand while resilience defines the grid's ability to withstand and recover from disruptions such as faults or cyber-attacks. Energy equity is the concept that the benefits of energy should be distributed fairly and justly, regardless of race, socioeconomic status, or ability. This dissertation, containing 3 projects, uses optimization and control to tackle these critical issues in the context of DER integration. Specifically, novel optimization algorithms and control strategies are proposed to reduce the extent of power outages using networked microgrids, to enable DERs and DER aggregations to participate in electricity markets while maintaining reliability, and to ensure DERs are treated equitably. Additionally, we present relevant sociotechnical analysis like how regulatory frameworks, market structures, and system operator decisions impact the benefits that DERs can provide society. In the first project within this dissertation, the system impacts of two different market mechanisms currently implemented by two U.S. independent system operators for managing the energy constraints of battery energy storage providing frequency regulation are analyzed. A qualitative comparison in terms of the responsibilities of involved parties, impacts on resource requirements, and how market rules impact utilization is presented. Controller and market simulations are used to quantitatively compare the two strategies in terms of regulation-signal following performance and additional system control effort. In the second project, we formulate a robust optimization problem for configuring a distribution network composed of networked microgrids to minimize load shedding and generator costs during contingencies, accounting for load uncertainty. After reformulation for tractability, we present a novel cutting-plane algorithm to solve the problem. In addition, we present a real-time optimal power flow algorithm to operate the DERs after reconfiguration and present modifications to the cutting-plane algorithm to improve scalability. Detailed numerical studies highlight the benefits of networked microgrids on system resilience and the significance of considering load uncertainty in operational decision-making. Without proper management DERs can cause reliability issues such as over- and under-voltages, over-current violations, and transformer overheating. In this three-part project, we investigate an existing method for managing DERs and DER aggregations, dynamic operating envelopes, to ensure network reliability. Dynamic operating envelopes, or simply operating envelopes, represent node-specific dynamic net export limits set by the system operator. In the first part of this project, we analyze market and social implications, comparing operating envelopes to another proposed DER aggregation management method. Next, we examine and address technical challenges in operating envelope implementation. Finally, we propose a more equitable implementation for determining operating envelopes. The novelty of our proposed fair-over-time implementation is that it allows the operating envelope allocations to be unfair at any time step but requires that the allocations be fair over the entire time horizon.
