Research on the Electricity Market Clearing Model and Price Fluctuation with Wind Power

The output of wind power is random and uncertain. As the proportion of wind power participating in the electricity market increases, it will have a great impact on the electricity price and the profit of traditional generators. Generating the scenarios of wind power by Monte Carlo method, this paper establishes unit commitment model and economic dispatch model of electricity spot market with wind power. Based on the actual operation data of a provincial electricity market, the changes of nodal price under different wind power penetration rates and different prediction accuracy of wind power are calculated. The influencing factors of electricity price fluctuation are studied, and the impact of wind power on the profit of traditional generators is analyzed.
