摘要
分布式可再生能源在配电网中的渗透率不断提升,将影响配电系统的安全稳定运行。作为一种具有时空灵活性的储能系统,移动式储能可提供各类公用事业服务保障配电网的安全稳定运行。为实现合理投资移动式储能,本文提出移动式储能接入位置与容量规划方法。首先,确定影响规划问题的不确定因素,综合考虑各不确定因素自身的时序相关性与相互间的互相关性生成运行场景。而后,构建两阶段随机优化模型,在第一阶段配置移动式储能数量并规划接入位置,第二阶段以不同场景下移动式储能在配电网中经济调度产生的期望效益评估第一阶段优化结果的合理性,并采用遗传算法与优化求解器的进行求解。最后,在IEEE-33节点配电网络和29节点交通网络中验证模型及算法的有效性。
The increasing penetration of distributed renewable energy in the distribution gird will affect the safe and stable operation of the distribution system.As a kind of energy storage system with spatial and temporal flexibility,mobile energy storage can provide various utility services to guarantee the safe and stable operation of the distribution grid.In order to achieve reasonable investment in mobile energy storage,this paper proposes a mobile energy storage access location and capacity planning method.First,the uncertainties affecting the planning problem are determined,and the operation scenarios are generated by considering the time series correlation of each uncertainty and the mutual correlation between them.Then,a two-stage stochastic optimization model is constructed.In the first stage,the amount of mobile energy storage is configured and the access location is planned;In the second stage,the reasonableness of optimization results in the first stage is evaluated by the expected benefits generated by the economic dispatch of mobile energy storage in the distribution grid under different scenarios,and genetic algorithm and optimization solver are used to solve the problem by using genetic algorithm and optimization solver.Finally,the validity of the model and algorithm is verified in IEEE-33 node distribution grid and 29 node transportation grid.
