Abstract

An energy storage scheduling method for photovoltaic-storage microgrids is designed, taking into account the concentrated response of electric vehicle （EV） charging demand. The composition structure and operating principles of photovoltaic-storage microgrids are comprehensively considered, and the influencing factors on photovoltaic-storage microgrids under concentrated EV charging demand response are analysed. Based on the analysis results in the context of concentrated EV charging demand response, scheduling constraints are set from aspects such as energy storage output, demand response, and power balance. Through the calculation of energy storage capacity and EV electricity demand, the results for energy storage scheduling quantities are obtained. Based on these results, a scheduling method is planned to accomplish the energy storage scheduling tasks for photovoltaic-storage microgrids. Experimental results indicate that, compared with traditional scheduling methods, under concentrated charging demand response, the average charging capacity and charging speed of electric vehicles reached 52.3 kWh and 89.6 kWh, respectively, while the balance degree of the photovoltaic-storage microgrid is significantly improved.
