Abstract: The randomness and intermittence of wind power make the cost of electricity generation increase greatly and exacerbate the imbalance between supply and demand. In the electricity market environment, the demand side has the ability to respond to the variations of energy price in short term, which can help the power grid to absorb wind power. Based on this feature, a generation expansion planning model which incorporates wind power and short-term demand response is established in this paper. The elasticity of own-price and cross-price, the constraints of CO2 emission intensity and the wind power reserve capacity are also taken into account. Moreover, through simulation, the power generation capacity is obtained. The experimental results not only validate the rationality of the model, but also prove that the introduction of demand response can increase the wind power penetration and reduce the cost of power supply.

Key words: demand response, power source planning, wind power generation, CO2 emission reduction, electricity market
