Abstract: Renewable energy, such as wind and solar energy, has significant clean characteristics, which can reduce the carbon emissions of the energy industry. However, the problem of abandoning wind and solar energy is still very serious in China. In order to promote the consumption capacity of wind and solar energy, this paper makes a deep research on the mechanism of clean energy absorption under the background of national unified electricity market. This paper analyses the engineering problems of the renewable energy consumption in China, and establishes a simulation model of the integrated energy system including combined heat and power system, natural gas boiler and wind and solar energy. Aiming at maximizing social welfare, a day-ahead market clearing model, which can promote the new energy consumption, is put forward for the integrated energy system. The clearing model considers the power demand side management, which makes the clearing model has significant characteristics of modern power system. The proposed day-ahead market clearing model has been simulated and validated in Matlab software. The simulation results verify the positive effect of the proposed clearing model on the renewable energy consumption.

Key words: day-ahead clearing, clearing price, new energy consumption, integrated energy system, social welfare
