Bi-level Optimization Strategy of Grid-side Multiple Energy Storage Stations Considering Available Capacity and Frequency Regulation Cost
摘要
Abstract
Aiming at the problem that some energy storage stations in a region lose charging/discharging capability in advance due to uneven distribution of frequency regulation instructions,resulting in insufficient response ability of subsequent frequency regulation demand,a bi-level optimization strategy of grid-side multiple energy storage stations considering available capacity and frequency regulation cost is proposed.The proposed strategy includes the frequency regulation power distribution layers of energy storage stations and energy storage units.The upper layer introduces the available capacity state coefficient and the adaptive coefficient about the adjustment ability of energy storage resources,and designs the optimal distribution model of frequency regulation power partition of energy storage station to realize the balanced distribution of frequency regulation power in each energy storage station.The lower layer takes into account the state of health(SOH),the resistance coefficient,and the balanced recovery of the state of charge(SOC)for the energy storage unit to construct the objective function,so as to prioritize the recovery of SOC for energy storage units with high SOH.The simulation results show that the proposed strategy can improve the response ability of the energy storage resources in the region and realize the maximum utilization of energy storage resources while ensuring a certain economy.关键词
