Power Pricing Algorithms Based On Incentive Stackelberg Strategy

Under power market circumstance, the establishment of a reasonable power price to consumers is very important. Power consumers can be motivated by the price to adjust their mode and structure of power utilization, and the power load can be kept in a stable condition. Therefore the efficiency and stability of power systems can be improved. As one of power prices to consumers, time-of-use (TOU) power price is applied in many countries of the world. And it is one of the important methods of Demand Service Management (DSM), which can accomplish the goal of load shifting and reducing costs of power consumers. At present, there are many power pricing policies. In the thesis, problems of power pricing with penalty are dealt with by means of game theory, and some power pricing algorithms based on incentive Stackelberg strategy are presented.First, aiming at the imbalance phenomenon of power resources in our country, incentive Stackelberg strategy is applied to set up incentive power pricing model of power market. The condition is supposed that power company provides a limited amount of electricity for every user, according to balance rule between supply and demand. The maximal utility function of user is considered to determine dynamically the new power price on a rationally developing power market. The algorithm taking account of incentive strategy is more reasonable than the singleness pricing as in the past. A linear strategy and two nonlinear strategies are proposed to the power pricing problem according to both the output capacity of power company and demand of users. Some numerical simulations are carried out for the linear strategy and two nonlinear strategies via MATLAB toolbox, and simulation results demonstrate the effectiveness and practicability of the proposed algorithms.Second, the power pricing model is constructed that the users themselves apply the amount of electricity. The main idea of the model is that users apply the amount of electricity, the part of excess or leavings will be appropriate punished. According to the...
