    摘要:

    在配电系统中使用诸如光伏、电池储能系统等分布式电源可实现灵活高效的无功补偿。为此,提出一种考虑分布式能源的配电网无功调度和储能优化的分析方法。该方法以运行成本为目标函数,结合前推回代算法和近似拟合法对分布式电源的无功调度和储能方法进行优化。最后,在2种配电系统中,采用实际太阳辐照数据和系统运行数据对该方法的有效性进行验证。结果表明,该方法可以消除对初始解和参数整定的依赖,求解速度比现有常用算法提高了50倍,可用于实时调度。

    Abstract:

    In distribution network, the application of distributed power resources such as photovoltaics and battery energy storage systems can achieve flexible and efficient reactive power compensation.Therefore, the reactive power dispatch and energy storage optimization considering distributed power sources is proposed.The operating cost is selected as the objective function, and thebackward-forward sweep algorithm and approximate fitting method are combined to optimize the reactive power dispatch and energy storage method of distributed network. In the end, the actual solar radiation data and system operating data are employed to verify the effectiveness of the proposed method in two power distribution systems. It is shown that this method does not depend on the initial solution and parameter tuning. Its solution speed is 50 times faster than the existing common algorithms, and can be utilized for real-time scheduling.
