Active Frequency Response Based on Model Predictive Control for Bulk Power System

To solve frequency stability problems caused by the high-power loss of ultra-high voltage faults and the high penetration levels of renewable energy, a method of active frequency response (AFR) based on model predictive control (MPC) for bulk power system is proposed. On the basis of the time-space...

Zusammenfassung:To solve frequency stability problems caused by the high-power loss of ultra-high voltage faults and the high penetration levels of renewable energy, a method of active frequency response (AFR) based on model predictive control (MPC) for bulk power system is proposed. On the basis of the time-space distribution characteristics of the frequency in power system, a control framework of AFR is built, in which the frequency response control is transformed from decentralized feedback control to centralized feedforward control, and the theoretical basis for the coordination and optimization of multiple frequency regulation means is provided. By using MPC, not only the control hysteresis problems caused by the existing frequency response delay are overcome, but also the regulation characteristics of types of frequency regulation means and the operation constrains of power system are comprehensively considered. Furthermore, on the premise of ensuring system operation safety, the frequency response capability of power system is fully utilized. The analysis and simulation results for a two-area interconnected power system with multiple sources and a real large scale power system show that the proposed method is feasible and effective.
