The application of wind power promotes the low-carbon progress in power industry

and its healthy development depends on a fair and efficient market mechanism fitting for wind power characteristics. Considering the low-carbon benefits and especially wind power participation in market bidding

a two-part compound bidding mode with the superiorities of both hourly and block bidding modes is proposed. This mode can properly evaluate the real power production cost and take the price advantage of varying wind power output by dividing one-part pricing parameter into two-parts

and its mathematical model and market clearing process are given too. The effects are analyzed including the power purchase costs

the social benefits

the load flattening

the supply-demand interaction and the capability of wind power absorption. The analyzed example indicates that the adoption of the two-part compound bidding mode can enhance market competitiveness of wind power

improve the system capability of wind power absorption

and relieve the pressure of wind power subsidies on the government as well. This work is supported by State Grid Corporation of China (No. DZN17201300045）.
