Design and Simulation Research of Multivariable MPC Controller on Interconnected Grid LFC
摘要
Abstract
In order to make the control of interconnected grid frequency having better load adaptability and maintaining the economic stability and reliable operation, a design method of multivariable predictive controller and its algorithm were proposed, based on the state-space model of the interconnected grid while considering the regional capacity constraint, and yet did not depend on the frequency deviation coefficient. According to the modeling and simulating of the two area grids frequency control systems, the proposed predictive algorithm was compared with the conventional algorithm via PI regulator in single area and dual zone load step disturbance, random white noise disturbance,etc. The results indicated that the proposed predictive control algorithm could significantly improve the recovery performance of the grid system frequency.关键词
