基于PSCAD/EMTDC搭建了永磁直驱风电场,并根据钒液流电池(VRB)的数学模型搭建了并网型电磁仿真模型。根据风电场的输出功率变化,设定相应的能量管理及控制策略,对含有钒液流电池的风电场进行仿真分析。仿真结果表明,钒液流电池可较好地平滑风电场输出功率的波动性,在一定程度上提供无功支持,改善电压稳定性。
Based on PSCAD/EMTDC, a permanent magnet synchronous generator(PMSG) wind farm was built and according to the mathematical model of vanadium redox flow battery(VRB) ,the grid-connected electromagnetic simulation model of the VRB was built. The corresponding energy management and control strategies were set up based on the variation output of the wind farm. Simulation and analysis of the wind farm with VRB were carried out. The simulation results indicate that VRB can well smooth volatility of wind farm, and provide reactive support in a certain extent and ameliorate the stability of voltage.
