摘要
风电集中并网给电力系统安全稳定运行带来新的挑战,配置储能则是改善电力系统静态和动态稳定性的有效手段。分析了储能在解决风电并网问题中的作用,基于液流电池建立了储能装置的机电暂态模型;以电力系统安全稳定为目标,应用数字仿真方法计算了风电集中接入的电力系统对储能的容量需求,提出了配置策略;针对中国典型风电接入电力系统,以保证电力系统静态和动态稳定性为目标,求取了该系统对储能容量的需求,并通过仿真计算验证了配置策略的正确性。
The wind power may cause ever-growing and serious stability hazard for power system, and energy storage plays a very important role in improving the static and dynamic stability of power system. The role of energy storage is introduced in solving wind power integration problem and an electromechanical static model of flow-based energy storage is set up. The capacity requirement of energy storage for system stability with wind integration is calculated by simulation, and relevant configuration method is proposed. In view of a typical power system with wind power integration, the required energy storage capacity is calculated with the proposed method for achieving the static and dynamic stability. Finally, simulation has proved the effectiveness of the proposed configuration strategy.
