Abstract: The friendly interaction between electricity users and power grid companies is an effective way to solve the current contradiction between energy supply and demand. In order to encourage electricity users to participate in power interactions, it is necessary to design a reasonable interaction mechanism. An incentive compatible interactive compensation price contract model is thus proposed for different types of users. Based on nonlinear pricing theory, the model takes the maximization of the interests of power grid companies as the decision-making goal, and considers the incentive compatible constraints of electricity users to determine the optimal interaction volume and compensation price corresponding to different types of users. Case study shows that the proposed pricing model has both pricing efficiency and operability. It can not only ensure the maximization of the interests of power grid companies, but also well encourage users to participate in power interactions. At the same time, it can guide users to disclose real type information, thus meeting the incentive compatibility characteristics of the users. It has both practical social and economic significance in the context of power market.
