Two-Layer Optimization Method of New Energy Power Grid Loss Reduction Potential Considering Comprehensive Benefits

To solve the question of high loss, low power quality and economical inspection, a double iteration method of line loss reduction and efficiency is proposed in this paper. Firstly, it analyzes the source of power grid loss and the transformation technical measures of power grid loss reduction, and studies the principle and effect of the transformation technical measures of power grid loss reduction. Secondly, the location and overall capacity of the reactive power compensator, the location of the controller, the location of the switch line and its relative value are the control variables, and it established outer programming model with the maximum benefit. Then, we used the butterfly algorithm to solve the problem, and get the optimal method of power network loss reduction. Finally, a power supply company line is tested, and it is proved that this method can be used to reduce line loss effectively.
