Assessing impacts of energy storage on resilience of distribution systems against hurricanes

Abstract

This paper develops a comprehensive framework to analyze the impact of energy storage on improving the resilience of distribution systems against hurricanes. This paper first develops a spatio-temporal model of progressing hurricane when making landfall that can be used to anticipate outage scenarios caused by the gust-wind speed. An optimization model is then developed for optimizing the operation of distribution systems during hurricane that captures both pre-outage and post-outage network operation constraints. Numerical simulations are performed on the modified IEEE 33-bus distribution system with real hurricane data in Houston to demonstrate the effectiveness of the proposed model.

Assessing operational benefits of large‐scale energy storage in power system: Comprehensive framework, quantitative analysis, and decoupling method

“…Assessment framework is first proposed to evaluate ESS's impact on the traditional power system. Based on different utilized functions of ESS, the traditional framework divides its benefits into two parts: (a) energy transfer benefits, 1‐11 and (b) ancillary services benefits 12‐39 . Since the RE penetration in the traditional power system is relatively low, the evaluation of traditional energy transfer benefits mainly focuses on ESS's benefits in reducing the system operation cost.…”

“…Therefore, it can replace the function of thermal units in frequency regulation at a high quality and a relatively low cost. Var regulation benefit 18‐20 : ESS can be used for var compensation operation. So, ESS can replace special var compensation equipment, saving a large amount of cost. Black start benefit 30‐33 : ESS can be used as the black start power supply. Hence, it can accelerate system restoration to minimize the loss caused by the accident outage.…”

“…Finally, some researchers use ESS as black‐start resource and investigate its benefits in accelerating system restoration during extreme events 30,31 . Numerical results show that the optimal sizing and siting ESS can significantly enhance power system resilience against various high‐impact low‐probability incidents, such as earthquakes 32 and hurricanes 33 …”

Wildfire Risk Mitigation: A Paradigm Shift in Power Systems Planning and Operation

“…Understanding and modeling of high-risk fire weather presents several opportunities to make decisions based on trade-offs both on and off power systems. Optimal power flow objectives such as minimizing load curtailment in public safety power shutoff scenarios through use of distributed energy resources (DER) has already been studied, though not in the context of wildfire risk mitigation (see e.g., [61], [63]). As DER become more cost-effective, a variety of operational optimization techniques could be used to guide operational practices, which would lead to a lower likelihood of wildfire ignition caused by power systems.…”

Power Outage Estimation: The Study of Revenue-Led Top Affected States of U.S

“…Similarly there are a number of recent studies where the research focus is to assess the impact on electric power systems specifically during or after a hurricane has occurred. [26][27][28][29][30][31]. There are several studies where the research motivation is to assess the impact of geomagnetic storms on the electric power system [32][33][34].…”
