Using Predictive Models for Real-Time Voltage and Reactive-Power Control in a Power System with Wind Farms
摘要
This paper presents a coordinated voltage and reactive-power control strategy for a wind farm (WF) and reactive-power compensation (RPC) devices based on model predictive control (MPC) in real time. The subject of research is an electric power system (EPS) with dynamic models of WF and RPCs. A mathematical model of the control system is formulated, and calculations are performed using a test EPS model to demonstrate the effectiveness of real-time application. It is shown that using normal and corrective (based on MPC) modes in the control system makes it possible to ensure a faster restoration of the mode parameters of the EPS within acceptable limits than in the absence of corrective control.
