Energy Trading for Multi-type Prosumer in Context of Electricity-Carbon Coupled Market

Abstract

The design of the transaction mechanism is one of the key points in the construction of the power market. This paper presents an energy trading method based on VCG auction mechanism for multi-type prosumer market. Firstly, the basic theory of VCG auction mechanism is introduced. Then, the mechanism of VCG market framework is designed. For the multi-type markets, an auxiliary parameter is used to establish the augmented Lagrangian model. The objective function of the model is transformed into several sub-problems, and the alternating direction multiplier method (ADMM) is used to solve the multi-block problem. In the real-time market phase, the stochastic nature of renewable power generation and fixed load is considered for real-time transactions with the power grid. Finally, the simulation results show that the proposed market transaction mechanism is economically beneficial to prosumers and the power grid, has high computational efficiency, and is beneficial to the sustainable development of the prosumer market.
