Research on Two-Level Rolling Scheduling of Wind-Solar-Storage Hybrid System Before Day-Ahead and Real-Time
Aiming at the intermittency and time-sequential characteristics of distributed energy generation,a model for economic optimal dispatch considering wind and curtailment in a wind-solar-battery hybrid system is constructed.Firstly,the hybrid energy system composed of distributed power sources and decentralized energy storage is taken the research subject,and the complementarity of wind,solar,and energy storage is studied to make wind and solar power generation have certain dispatchability.Secondly,day-ahead and hour-ahead rolling economic dispatch model of the hybrid system is studied with the dual objectives of economy and stability.Finally,the economic and feasibility of the strategy and model algorithm proposed in this article are verified through simulation analysis of the IEEE-30 node 6 unit system.
