摘要
分布式储能是虚拟电厂的优质可调节资源。为提高含分布式储能的虚拟电厂收益,构建了虚拟电厂中柴油发电机和风光可再生能源机组的模型;分别建立了并网型储能与用户侧储能两种分布式储能的运行约束条件;基于日前市场分时电价对虚拟电厂资源进行了优化调度算例分析。研究结果表明,受需量约束的限制,用户侧储能的收益能力不如并网型储能;不同需量约束将影响用户侧储能为虚拟电厂进行电价套利的能力;用户侧储能的个数越多,虚拟电厂的总收益越少。
Distributed energy storage is a high-quality adjustable resource for virtual power plant,in order to improve the benefit of virtual power plant with distributed energy storage,a model of diesel generator and wind and solar renewable energy unit in virtual power plant is constructed.Two types of distributed energy storage,grid-connected energy storage and user-side energy storage operation constraints are established.And based on the day-head market electricity price,the optimal scheduling case of virtual power plant resources is analyzed.The research results show that due to the restriction of demand constraint,the benefit capacity of user-side energy storage is not as good as that of grid-connected energy storage.Different demand constraints will also affect the electricity price arbitrage ability of the user-side energy storage for the virtual power plant,and the more the number of user-side energy storage,the less the total benefit of the virtual power plant.
