摘要本文介绍了一种基于蓄电池的控制方法，以减少光伏输出功率的波动，这反过来又会减少电力系统的频率偏差。这里介绍的电池控制方法将保持充电状态接近50%。因此，它将增加电池的寿命，并降低维护成本。该电池控制方法提供了局部搜索算法，以搜索平滑光伏输出功率波动所需的电池的最佳容量。然后，提供成本比较以实现搜索算法的性能。为了验证所提出的方法的有效性，仿真结果给出了使用实际的日照和负载数据。
Abstract This article explains a battery-based control method to reduce the photovoltaic output power fluctuations, which, in turn, will reduce the frequency deviations of the power system. The battery control method introduced here will maintain the state of charge near 50%. Therefore, it will increase the lifetime of the battery, as well as decreasing the maintenance cost. A local search algorithm is provided with this battery control method to search the optimal capacity of the battery required for smoothing the photovoltaic output power fluctuations. Then, a cost comparison is provided to realize the performance of the search algorithm. To verify the effectiveness of the proposed method, simulation results are presented using the actual insolation and load data.
