摘要
随着风电渗透率在电力系统中的不断增大,风电无法并网的现象越发严重,弃风问题亟待解决。为减少弃风,将风电以电锅炉风电采暖的方式接入电网,并引入蓄电池储能装置,建立包含风电的电锅炉-储能联合系统消纳弃风的小型电力系统模型。利用DIgSILENT/PowerFactory仿真软件,通过对电锅炉与储能装置的控制,对比分析了系统加入电锅炉-储能联合系统前后弃风消纳的情况。仿真结果表明,配置电锅炉储能联合系统后,能有效促进系统对风电的进一步消纳。
With the increasing wind power penetration in power system,the phenomenon that wind power cannot connect to the grid gradually serious,the problem of abandoned wind is urgent to solve.In order to reduce abandoned wind curtailment,the wind power will be connected to the power grid by electric boiler heating and introduce energy storage to build up a small power system model of electric boiler energy storage system incorporating wind power for absorbing abandoned wind.Using DIgSILENT/PowerFactory software simulation and through the control of the electric boiler and the energy storage link,the wind power consumption of the system is compared and analyzed by adding the electric boiler energy storage system before and after.Simulation results show that the model can promote accommodation of wind power by configuring the joint system of electric boiler and energy storage.
