Game Analysis of Multi-energy Market considering Integrated Energy Suppliers with Wind Power

The multi-energy complementary nature of integrated energy systems contributes to the consumption of intermittent renewable energy sources. In order to reflect the market value of integrated energy systems and encourage their investment and development, it is a trend for integrated energy suppliers (IES) to compete in multi-energy markets. The joint game problem of IESs with wind generators (WG) participating in both electricity market and natural gas market is investigated in this paper. A joint equilibrium model of multi-energy market is established considering the penalty mechanism of wind power bid deviation, and the nonlinear complementary method is used to solve the equilibrium model. Numerical examples are presented to verify the rationality and validity of the model. It is shown that as the wind power penetration increases, the electricity and gas prices will decrease, and the profits of the IESs and the total social welfare will increase.
