摘　　要：针对分布式能源发电的间歇性和时序特性,构筑风光储混合系统中考虑弃风、弃光等因素的经济优化调度的模型。首先,以分布式电源及分散式储能组成的混合能源系统为研究主体,研究风能、光能、储能多种能源互补,使风电、光电具有一定的可调度性。其次,从经济性和稳定性双目标建模,研究混合系统的日前和时前两级滚动经济调度模型。最后,通过IEEE-30节点6机组系统仿真分析,验证了本文所提调度策略及模型算法的经济性与可行性。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.
