摘要：AbstractThis paper presents the modeling and analysis of discrete automatic generation control (AGC) in a two-area power system. The network is modeled with nonlinearities and coordinated with renewable energy resources. The primary and secondary control loops constantly attempt to lower the error signal to zero by sending control orders to the speed representative valve. Generally, the discrete control pulses are used to change the outputs of the generating unit in discrete stages. However, the AGC has been treated as a continuous controller in recent literature. The nonlinearities and renewable penetration are missing in the design of discrete supplementary controller models. Therefore, the impact of nonlinearities and renewable resources on a discrete two-area power system model is discussed in this work. The simulation of the discrete controller is performed to observe the dynamic response of the power system under renewable penetration. It is observed that inappropriate selection of speed regulating droop, sampling time, and system inertia may lead to degraded dynamic performance or possibly induce system instability.
