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.
