Analyzing and Mitigating the Impacts of Grid-edge Technologies on Power Distribution Networks

When

10 – 11 a.m., Oct. 18, 2023

Abstract:         In this talk, we first present a new rapid estimation method (REM) to perform stochastic impact analysis of grid-edge technologies (GETs) to the power distribution networks. The evolution of network states' probability density functions (PDFs) in terms of GET penetration levels are characterized by the Fokker-Planck equation. The approach is illustrated on a large-scale, realistic distribution network using a modified version of the IEEE 8500 feeder, where electric vehicles (EVs) or photovoltaic systems are installed at various penetration rates. Second, we design an incentive-based mitigation strategy for equipment overloading leveraging the REM. The objective is to shift the EV charging during the peak hours when the equipment is overloaded to the off-peak hours and maintain equipment service lifetime. The incentive level and corresponding contributions from customers to alter their EV charging habits are determined by a search algorithm with provable convergence guarantee. The strategy is illustrated on the same IEEE 8500 feeder with a high EV penetration to mitigate overloads on the substation transformer.
