Abstract:
Because of the large peak-to-valley difference between intermittent loads and the randomness of distributed photovoltaic power output,the pv-storage microgrid with intermittent loads needs to be equipped with large-capacity energy storage devices to maintain the stable operation of the microgrid and improve its power supply capacity. This paper firstly analyzes the different types of intermittent loads and their adverse effects on voltage stability when they are connected to the microgrid. Then,with the minimum operating cost of the microgrid as the objective function and the minimum power point fluctuation as the constraint condition,the improved particle swarm algorithm(IPSO)is used to solve the energy storage configure the optimal value of the capacity. Finally,verifying with actual examples that the pv-storage microgrid with intermittent load,it uses this method to configure the capacity,which can not only reduce the operating cost of the entire microgrid,but also reduce power fluctuations in the microgrid.
