摘　　要：推进园区电能替代是改善环境问题的重要措施,针对综合园区能源系统进行电能替代受配电网络改造限制的情况,提出采用风光储系统作为供电系统的方案。首先构建综合园区能源系统中电替热、电替冷和电替油负荷模型。然后提出考虑配电网运行状态和需求响应的风光储最优容量双层配置模型,该模型包括配电网层和风光储系统层。最后采用Cplex进行求解,得到综合园区电能替代下考虑配电网运行状态和需求响应的风光储系统最优配置方案。通过IEEE 33节点系统以及某实际园区的电能替代负荷数据进行仿真计算,结果表明采用风光储系统供电并计及负荷的需求响应能解决园区电能替代负荷增长的需求并兼顾其最优经济配置。Promoting the electric energy substitution of integrated park is an important measure to improve environmental problems.The electric energy substitution of integrated park is affected by distribution network transformation.The program of electric energy substitution to configure wind-solar-battery system is proposed.Firstly,the load characteristic model under electric energy substitution is established which involves the load models of electricity replacing heat,cooling and fuel oil.Secondly,the bi-level optimal model for wind-solar-battery capacity allocation is proposed considering the reliability of distribution network and the demand response,which is concluded distribution network layer and wind-solar-battery system layer.Finally,Cplex is used to solve the problem,and it is obtained the optimal planning scheme of the wing-solar-battery system considering the reliability of distribution network and the demand response in the electric energy substitution of the integrated park.In the system of IEEE 33-node system,the electric energy substitution load data of an actual park is used to perform simulation.The results show that the use of wind-solar-battery system for power supply and the consideration of load demand response can solve the demand for electric energy substitution load growth in the park and realize the wind-solarbattery system's optimal economic configuration.
