Intelligent Analysis of Line Loss Based on Game Theory Combined with Weighting - TOPSIS Method

In the line loss management of power grid power supply companies, there are problems such as incomplete line loss indicators, unreasonable indicator weights, and strong subjective preferences. To solve these problems, we constructed a line loss indicator system, used the idea of game theory to combine subjective weights and objective weights, and used the TOPSIS method to study the line loss management of power supply companies. Among them, the G1 method was used to determine the subjective weight, without consistency checking, which is concise and efficient. The objective weights were determined by the CRITIC method, which took into account not only the intensity of comparison among indicators but also the conflict of each indicator. The experimental results showed that the game combination weighting had a more accurate and objective indicator weight value, and the TOPSIS method could optimize the line loss more comprehensively.
