基于二层规划的用户侧储能容量配置和最优运行策略分析

摘要

In recent years,the development of smart grid in China is gradually promoting,energy storage system (ESS)is one of the key technologies to support the development of smart grid,its economic benefit analysis is very important. This paper improves the life cycle cost (LCC)model of ESD first,then establishes the comprehensive benefit optimization operation strategy and capacity alloca-tion model of ESD based on bilevel programming through analyzing the cost-benefit efficiency which generated by the energy storage device (ESD)of demand side,finally obtains optimal daily operation strategy and capacity of ESD through iteration of the upper and lower model. Simulation analysis of example is carried out by using particle swarm optimization algorithm,the result shows that the outstanding operation strategy and reasonable storage capacity can bring a certain economic benefits,and with the development of the electric market,the installation of energy storage device on the demand side will bring better economic benefits.%近年来，智能电网在中国的发展正在逐步推进，储能作为支撑智能电网发展的关键性技术，其经济效益分析至关重要。本文首先完善了储能全寿命成本效益模型，在此基础上利用二层规划理念建立了储能装置综合效益最优时的容量配置和运行策略分析模型，通过上下层模型的迭代计算最佳日运行策略及储能容量和功率最优配置。最后采用粒子群优化算法对算例进行了仿真分析，结果表明，用户侧储能装置良好的运行策略和合理的储能容量设置可以带来一定的经济效益，并且随着电力市场日趋完善，用户侧安装储能装置的效益会日趋优异。
