受端电网负荷量大,需求侧响应能力较强,在储能配置阶段考虑需求侧响应能力,可降低储能的配置容量,进一步提高储能配置的经济性与可行性.以受端电网储能为主要研究对象,提出了一种计及受端电网需求侧响应能力的储能配置方法,用于分析需求侧响应对储能的替代作用.以储能配置成本、弃风弃光成本、需求响应补偿成本和切负荷成本最小为目标函数,实现多元储能的优化配置;通过控制需求侧响应的容量和价格参数,分析需求侧响应对储能容量配置的影响.通过算例分析发现,需求侧响应对磷酸铁锂储能替代作用明显,且需求侧响应的价格参数对储能容量配置影响更大.
Receiving-end power grids are characterized by substantial loads and demand-side responsiveness.Con-sidering demand-side response during energy storage allocation can reduce allocation capacity,thereby enhancing the economy and feasibility of the allocation.The paper focuses on energy storage within the receiving-end grid and introduces an energy storage allocation method that takes account of the grid's demand-side response capacity.This method aims to analyze the potential for replacing energy storage with demand-side response.The optimal allocation of multiple energy storage is achieved by minimizing the storage allocation cost,cost of wind and solar PV genera-tion curtailment,demand response compensation cost,and load shedding cost as the objective functions.The im-pact of demand-side response on energy storage capacity allocation is analyzed by controlling the capacity and pric-ing parameters of demand-side response.It is revealed through a numerical analysis that the demand-side response plays a significant role in substituting lithium iron phosphate battery energy storage,and that the pricing parameter of demand-side response exerts a more substantial impact on energy storage capacity allocation.
