Primary Frequency Control of Wind-solar-storage Power Station Considering Discrete Control Nonlinearity

Abstract With the gradual advancement of dual-carbon goals, wind-solar-storage power station has become mainstream trend in constructing new energy stations due to their wind and luminous complementary characteristics. However, current research on primary frequency control is still focused a single-machine strategy. The communication delay period caused by long links are not considered. It difficult describe influence difference dynamic characteristics performance. Therefore, this paper takes multi-layer link as object, establishes nonlinear model considering period, puts forward plant method, which suitable for participating grid.
