Research on Energy Storage Configuration in Distribution Networks for Integrating New Energy Consumption
The high proportion of distributed power sources connecting to distribution grids has introduced significant challen-ges,including poor system stability and economic inefficiency in planning.To achieve rational allocation and efficient integration of distributed power sources,this paper proposes a hybrid energy storage configuration method for distribution grids.Firstly,to meet the demands of seasonal source-load regulation and short-term flexible economic operation,a hybrid energy storage system energy management strategy is developed,integrating pumped hydro storage with battery energy storage.Secondly,aiming to minimize annual comprehensive costs,a dual-layer planning model for hybrid energy storage system configuration is estab-lished,with distribution grid operation and distributed power source utilization as lower-level objectives.Finally,by employing particle swarm optimization and mathematical programming algorithms,optimal configuration capacities and power allocation results are derived.This approach effectively addresses issues such as low distributed power sources utilization,load and voltage fluctuations,while simultaneously reducing system planning costs.
