摘要
针对特高压注入后直流闭锁故障时大功率失去的问题,提出一种备用辅助服务下弥补大功率缺额,进行机组组合优化调度的方法。通过仿真算例验证备用辅助服务参与下的机组组合成本有效降低。结果表明,方法对电力经济调度优化有重要意义,同时对于提高发电厂提供辅助服务的积极性,促进主能量和辅助服务的均衡协调供应也有着重要意义。
Considering loss of high power in case of DC blocking fault occurring after UHV injection,a method for compensation of high power vacancy under standby auxiliary services and for optimized scheduling of unit combination was presented in this paper.Simulation examples verified that the unit combination cost was reduced greatly with participation of standby auxiliary service.The results indicated that the proposed approach could be of great significance to the optimization of power economic dispatch.In the meantime,it was also important for the enhancement of the initiative of power plants to provide auxiliary services and for the promotion of balanced and coordinated supply of main energy and auxiliary services.
