An evaluation method of power market operation efficiency based on Grey Relational Analysis of entropy weight method

Power market is a complex grey system, and there are many factors affecting its operation efficiency. In order to better supervise the operation efficiency of the power market, this paper summarizes the previous studies, sorts out twelve relative factors that affect the operation efficiency of the power market, and proposes a method to calculate the correlation degree between each factor and the operation efficiency, that is, on the basis of grey correlation analysis method, entropy weight method is introduced to obtain the target weight. This method eliminates the subjective factors and makes the calculation results more convincing. It provides a reference for the market supervision department to supervise the operation efficiency of the electricity market.
