Abstract：The new technology of microgrid as grid-connected distributed power supply is inevitably affected by the energy loss of grid-connected lines.This paper starts from the point of minimizing the energy loss of energy storage in microgrid,focusing on the voltage loss and power loss of power supply.One aspect,the photovoltaic power generation system,the wind power genera-tion system,the micro-gas turbine and the storage battery group are used to construct the micro-grid structure,and the grid-con-nected lines of different power generation systems are divided into two cases.The objective function in the process of voltage drop is deduced by the voltage phase change of the transmission power line,and the energy optimization constraint condition is constructed by combining the power loss of the load.The experimental results show that the proposed method can quickly calculate the minimum voltage and power loss of the power supply,and give the different branches of different power system at the function stagnation point and complex power loss.
