Sichuan power grid mainly embraces hydroelectric power, and also contains a variety of other energy resource, such as gas turbine generating units and coal fired generating units, in which the performance of generation units varies widely, and therefore the coordinate control between automatic generation control (AGC) units becomes very urgent and important. According to the characteristics of AGC units, a dynamic grouping scheme is proposed, that is each regulation group follows different load parts separately, the units’ cooperation in time dimension is realized. Meanwhile, to improve units’ schedule performance, an adaptive balance control strategy is proposed either, which is to switch units’ dispatch strategy automatically according to the characteristics of load curve. The on-spot operation shows that the proposed strategies adapt Sichuan Grid''s power resource structure characteristics and its performance requirements well, the dispatching control quality is improved efficiently and the balance coordinated regulation between multiple units is realized.
