Abstract :
Cooperative game theory is firstly introduced into the comprehensive assessment of power quality, and a new model for combination evaluation of power quality is established based on cooperative game. The model takes into account the advantages of 4 kinds of single assessment method. By calculating the characteristic function values of various combinations to get the Shapley value of each assessment method, and then the weight value of each method in combination union can be determined, so that power quality assessment conclusion could be optimized. The conclusion also reflects the information of evaluation object from different angles. The simulation results show that the combination evaluation method with good accuracy can be effectively applied to the comprehensive assessment of power quality.
