Comparison of Mobile Energy Storage Output Strategy and Operation Economy of Low Voltage Distribution Network with Distributed Generation Access

Abstract

The operation economy of distribution network is an important part of the economic evaluation of distribution network, which directly affects the power consumption efficiency of users. With the rapid development of mobile energy storage technology and the access of multiple types of distributed generation to low-voltage distribution network, how to quantitatively evaluate the operation loss of distribution network and analyze the access of mobile energy storage to different forms of distribution network has important guiding significance for the planning and operation of low-voltage distribution system in the future. According to the typical topology of low-voltage AC and DC distribution systems with multiple types of distributed generation access, a comparative evaluation model of AC and DC operation economy based on the power loss of the whole link of the system is established, and an optimization model of distribution network operation strategy considering the state of energy storage charge and discharge is established with the optimization goal of operation economy.
