Abstract: There are abundant resources including wind energy, water energy, coal and so on in northwest region, which is the important base of the wind power, water power and coal power. To promote the high-efficient consumption of wind power in the large-scale power base of northwest region, the further research of technology, economy and other issues is required. Overall considering the harmonious development of the wind power, water power and coal power, and combining the actual conditions in northwest region, the wind power grid connection in northwest region and the induced share mechanism of ancillary service cost and expense for the peak-load regulation have been focusedly studied. Based on the analysis of the stakeholders related to the coordinated operation of wind power, water power and coal power, the assistant service framework for the promotion of high-efficient wind power consumption is proposed. According to the principle of equity of right and obligation based on the idea“Who get benefits paid”, the cost analysis model of paid peaking service considering the wind power grid connection is proposed, and furthermore the share mechanism that the paid peaking cost be solely shared in each Province for the thermal power and centralizedly shared in the grid for the water power is established. The analysis results of the example has proved the effectiveness of the proposed method.
