摘要
利用直流输电技术,以解决风电并网的波动问题。研究分析有源型电压源直流输电技术,通过控制并联储能单元的充放电功率,补偿风电的波动功率,从而稳定注入电网的风电场功率,通过储能控制系统达到控制母线电压的稳定。仿真结果验证了控制策略的可行性。
In this paper, a control strategy of a VSC-HVDC system with energy storage is sued to solve the problem of fluctuations of wind power and network. By controlling the parallel charging and discharging power of Energy storage unit, wind power fluctuations in power compensation to stabilize the wind into the power grid, through the energy storage system can control bus voltage stability. Simulation results demonstrate the feasibility of control strategy.
