摘要：
Based on online dynamic clustering with thoughts of "overall electric quantity equity and cluster power equity", a two-stage optimization method of renewable energy active power control is proposed, which can be used to solve the dispatching equity problems for renewable energy power plants. At the first stage, a comprehensive coefficient is formed based on indices such as the electric energy execution and grid-related performance of renewable energy power plants. Considering peak load regulation, reserve and constraints of grid security, an optimal control model for maximizing the overall output power with the comprehensive coefficient is established to achieve the overall electric quantity equity. At the second stage, clustering optimization and multi-scheme optimization is adopted to correct the lowest boundary of active power commands of each renewable energy power plants cluster, identify the feasible power equity optimization schemes of each cluster, then realize both power equity and electric quantity equity through the combined optimization of each cluster optimization scheme. The method is applied to several provincial power grids, and the actual system operation results show the effectiveness of the method. © 2019 Automation of Electric Power Systems Press.
