Day-ahead scheduling method for the power system considering the operation friendliness of wind power

The operation friendliness of wind power has a significant impact on the safety and economy of system operation. The scheduling optimization method in the day-ahead stage considering the operation friendliness of wind farms is proposed in this paper. Wind farm prediction accuracy, output fluctuation characteristics, and source-load complementarity characteristics are selected as friendliness indicators to evaluate the generation characteristics of wind farms. The wind power friendliness evaluation method is proposed. The day-ahead hierarchical scheduling model considering evaluation results of operation friendliness is constructed. The upper model formulates the scheduling plan for the wind power and thermal units to minimize the comprehensive cost. The lower model forms power constraints based on the friendliness indicator, and formulates the day-ahead scheduling plan of each wind farm, giving priority to the consumption of high-quality wind power. The numerical analysis verified the effectiveness and feasibility of the proposed method.
