A optimized scheduling scheme for internal energy storage of distribution networks with distributed photovoltaic generations is proposed,aiming at mitigating power fluctuation at the grid connection point and minimize the system pow-er loss by adjusting the charge and discharge of energy storage batteries.According to the known power output curve and load curve of photovoltaic generation,an energy storage optimized scheduling model is constructed,and the genetic algo-rithm(GA)is used to solve the proposed model.A simulation analysis conducted on the IEEE 17-node system verifies the effectiveness of the proposed model.
