A Model Predictive Control for Gird-Forming Voltage Source Converter
摘要
In response to the issue of insufficient frequency and voltage regulation capability in high-penetration renewable energy system, a control strategy combining grid-forming voltage source converter (GFM-VSC) with model predictive control (MPC) is proposed. Based on the main circuit topology of the converter, a power prediction model is established. Then a cost function concerning both inductor current and power output is constructed and a control strategy based on the which is introduced. A fast dynamic response to frequency and voltage variations has been achieved. Simulations have confirmed the effectiveness of the proposed control strategy.
