With the rapid development of wind power, the abandoned wind phenomenon is becoming increasingly serious. In order to study the reasonable scale of wind power development in the region, it is necessary to study the power grid construction and operation cost in different areas. In this paper, the optimal operation model of wind power is established, which is based on the abandoned wind rate. The model takes into account the generation cost, the penalty cost of the abandoned wind and the investment cost of the new line. The generating cost of the unit includes the cost of starting and stopping of the thermal power unit and the cost of the wind turbine. Abandoned wind penalty cost refers to the reduction of abandoned wind power, with certain amount of wind power curtailment of wind field punishment. The investment cost of the new line is obtained by multiplying the length of the unit length of the line by the length of the new line, and converting the cost to the level of the year. Finally, the reasonability and feasibility of the proposed method are verified by a provincial power grid case.
