摘　　要：随着大规模分布式发电接入配电网,其出力与负荷需求在时序上的不匹配性引起供电区域新能源难以消纳。为此,提出提升新能源消纳能力的供电区域源-荷-储联合优化配置方法。以配电网供电区域分布式电源、储能及可控负荷为配置对象,构建储能及可控负荷调用策略;建立供电区域源荷储二层联合优化配置模型。上层模型以实现分布式电源的最大消纳为优化目标。下层模型以供电区域内净负荷期望值峰谷差最小为优化目标。针对DG及负荷出力时序差异性,采用LHS技术进行处理;采用智能优化算法对模型进行求解。以某市供电区域拓扑结构为例进行算例分析,证明方法的合理性与有效性。With the large-scale distributed generation connected to the distribution network,the timing mismatch between its output and load demand makes it difficult to absorb new energy in the power supply area.For this reason,an optimal allocation method of power supply regional source-load-storage is proposed to improve the capacity of new energy consumption.Taking the distributed power supply,energy storage and controllable load in the power supply area of the distribution network as the configuration object,the energy storage and controllable load transfer strategy is constructed,and the two-layer optimal allocation model of source,load and storage in the power supply area is established.The optimization goal of the upper model is to achieve the maximum absorption of distributed power.The optimization objective of the lower model is to minimize the peak-valley difference of the expected net load in the power supply area.In view of the difference between DG and load output time series,LHS technology is adopted to deal with it,and intelligent optimization algorithm is used to solve the model.Taking the power supply area topology of a city as an example,an example is given to prove the rationality and effectiveness of the method.
