摘　　要：通过对风电并网后系统备用需求变化特性进行分析,发现风电并网后小概率备用需求增加的特性。针对这一特性,提出应用高赔偿可中断负荷作为一种备用支持配合传统备用,满足风电并网后系统增加的备用需求。采用传统备用和高赔偿可中断负荷两种备用相互协调配合的方式,构建了备用成本最优化模型,进而确定高赔偿可中断负荷在系统增加备用中的最佳比例。该方法在确保风电并网后系统安全稳定运行的前提下,节约了系统备用成本,从而提高了系统运行的经济性。仿真验证了风电穿透功率、风电预测误差、备用报价等因素对高赔偿可中断负荷占增加备用比例及系统备用成本的影响。After analyzing the characteristics of reserve demand by wind power integration, this paper found that small probability reserve demand increasing after wind power integration. For satisfying the increased reserve demand, using the high compensation interruptible load as a reserve support for cooperating with the traditional reserve is proposed. Based on the increased reserve requiring method which integrating the traditional reserve and high compensation interruptible load, the reserve cost optimization model for determining the best proportion of high compensation interruptible load is constructed. In the context of guarantying the safety and stability of the system, this method would save the reserve cost and improve the system operation efficiency. The influence factors of the cost optimization model include wind power penetration, wind power forecast error, reserve bidding, etc. Simulation results demonstrate that there factors how influence the proportion of high compensation interruptible load in increased reserve demand and the cost of the system reserve.
