AGC闭环实现电网深度调峰关键技术探讨

Disscussion on Key Technology for Realization of Deep Peak Shaving of Power Grids by AGC Closed Loop

受到国内经济形势变化、电网火电机组供热期调峰能力降低、风电反调峰等多方面因素影响,目前华北电网峰谷差愈来愈大,电网调峰压力加剧。结合京津唐电网某直调电厂机组灵活性改造情况,对AGC闭环实现电网深度调峰关键技术进行了探讨,为相关火力发电企业机组深调峰改造提供了借鉴。

Affected by the changes in the domestic economic situation, the reduced peaking capacity of the thermal power unit during the heating period and the counter peaking of wind power, the peak-to-valley difference in the North China power grid is increasing, and the peaking pressure of the power grid is intensifying. Combining with the flexibility transformation of a direct-regulating power plant in Beijing-Tianjin-Tangshan power grid, this paper discusses the key technologies to realize deep peak shaving of power grids by AGC closed loop. It provides reference for the deep peak adjustment of related thermal power generation enterprises.
