AGC Aid Coordination Strategy of Hydropower Units under the Conditions of Large-scale Wind Power Grid
YANG Shangming
Abstract：With the increase of the wind power penetration, the power fluctuation caused by uncertainty will grow significantly. Recently, the number of thermal power units is gradually decreasing. So the ther?mal power units related to the AGC will have no enough capacity to regulate the wind power fluctuation and this leads to the frequency stability problems. Based on this trend, this paper comes up with the coor?dination factor. Taking advantage of the hydro generating unit in the AGC control and is using more regu?lating resources will realize the coordinated control and can suppress the impact of the wind power uncer?tainty. The simulating results show that the strategy proposed in this paper can accommodate to the exist?ing dispatching control framework and has better coordinated control effect on the wind power fluctuation.
