Batteries as Grid Non-wires Alternatives: Reliability Improvement and Peak Load Shaving BESS Design
In this comprehensive walkthrough, we explore the case study of a realistic distribution feeder (based on an actual project) to understand how battery energy storage systems (BESS) can be utilized as distribution Non-wires Alternatives (NWAs). In the examined case, we go over how to design a grid battery to provide back-up power and improve reliability for customer load concentration at the end of a long radial feeder. The video delves into the detailed analysis of outage events, primary application sizing for reliability, and secondary applications such as deferring substation upgrades. It covers how to simulate the electrical feeder load, account for future load growth, and implementing various dispatch parameters and schedules for energy equalization (daily energy neutrality for the BESS) and peak load shaving. The video concludes with the BESS's performance metrics and potential efficiency improvements.
