Finite State Model Predictive Direct Power Control of Grid-connected Inverters for PV Systems
摘要
Abstract
For the problems of unfixed switching frequency,complicated design of output filter and high sampling frequency in the traditional direct power control of grid-connected inverters,a finite state model predictive direct power control method was proposed which was based on constructing prediction model of the finite state direct power control of grid-connected inverter for PV system. In the proposed method the instantaneous active and reactive output power were predicted,according to the cost function,the voltage vector,which minimizes the output power ripple was selected and applied to the next sampling period. Besides,a delay compensation scheme was designed for the system,and the dynamic power adjustment was realized. Simulation and experimental are given to validate the effectiveness of proposed solution.关键词
