The capacity of distributed photovoltaic impacts the safe and reliable operation of the distribution network. Energy storage in distribution feeders has emerged as a pivotal solution for consuming distributed photovoltaic. However,it is challenged to balance the economic viability of energy storage investing and grid reliability. In response,a method of optimizing the configuration of energy storage in distribution feeders based on the new model of counter configuration of the renewables from energy storage is proposed,which takes into account both the economy and reliability aspects. Firstly,an economic model for optimizing energy storage in distribution feeders is established. Secondly,a grid reliability simulation is performed based on the results of the economic optimization of energy storage in distribution feeders. Finally,considering the comprehensive indexes of economy and reliability,the different nodes are evaluated for site selection using technique for order preference by similarity to ideal solution (TOPSIS),and the energy storage configuration scheme is determined by the cumulative distribution curve. The simulation results show that the consuming capacity of distributed photovoltaic in the distribution feeders is effectively improved,and better balance the economic viability of energy storage investing with grid reliability,which can be used as a reference for the reasonable determination of ratios of the energy storage for renewables.
