Multiplexing Strategy for User-side Battery Energy Storage System Based on Dynamic Power Distribution and Short-term Capacity Compensation
摘要
Abstract
The user-side battery energy storage system(BESS)plays an important role in maintaining the power balance of the power system with high penetration of renewable energy,and its multiplexed operation mode for energy arbitrage and frequency regulation attracts extensive attentions.However,the dispatching of BESS faces the dual challenges of the time-varying energy arbitrage price and the random frequency regulation demand in the multiplexed operation mode.To make better use of BESS resources and maximize the demand-side BESS daily profit,a multiplexing strategy for user-side BESS based on dynamic power distribution and short-term capacity compensation is proposed,and a scheduling result is formed with the arbitrage power,droop coefficient and capacity compensation coefficient as the core parameters.The simulation results show that the dynamic power distribution achieves the dynamic adjustment of BESS power between energy arbitrage and frequency regulation.Meanwhile,the short-term capacity compensation accomplishes the continuous track of frequency deviation signals and effectively avoids the overload of capacity.The profits of BESS are significantly improved with the application of the strategy.关键词
