A multi-objective optimization model considering users' satisfaction and multi-type demand response in dynamic electricity price

Abstracts Dynamic electricity price mechanism is an important regulation method adopted by power companies in various countries to solve the contradiction between source and charge. According to the principle of consumer psychology, a non-cooperative Stackelberg model is constructed based on game theory to study the demand response characteristics of multi-type users. The model classifies users to realize the comprehensive consideration of users with different preferences. Meanwhile, it quantifies the impact of grid load fluctuation on the benefits of the power company and users' satisfaction with electricity consumption. Finally, the model is applied to a practical example, the Nash equilibrium solution of the model is obtained by NSGA-Ⅱ algorithm, and the sensitivity analysis of correlation coefficient is carried out. The results show that the model has a good effect on utility optimization of power supply and demand.
