Complexity Measure and Operational Efficiency Evaluation of Electricity Engineering Market

Abstract With the continuous development of the electricity market, its character as a complexity system is increasingly revealed, which requires that we should integrate complexity theory into the evaluation of electricity market operation and should have the systems engineering way of thinking at the same time. This paper uses entropy to measure the complexity of the electricity market, then regards complexity as an indicator and integrates it into the index system of electricity market, after that a model which is modified based on entropy theory to evaluate the operation efficiency of the electricity market is established. Finally, the complexity and operational efficiency of the electricity market are evaluated by simulating data. Form consequence we can find that the complexity of the electricity market is higher than the general market, the efficiency of region 5 is relatively low, region 3 is the most efficient, other four regions are small in difference. The result shows that the entropy as a measure of the complexity of the electricity market is simple in calculation, it can also accurately reflect the complexity of the electricity market. The use of chaos optimization of entropy-random DEA model has good flexibility and feasibility for the evaluation of the operational efficiency of the electricity market.
