| Abstract: | A simulation system for single-phase off-grid PV power-generation control is presented. DC / DC and DC / AC topological structures are adopted to study and design the PV off-grid system. The control system is based on energy coupling among the PV module,the filtering capacitor and the power convertor. It applied the double closed loop PI control strategy,stable DC bus voltage and inverter output are carried out. The designed PV off-grid system is simulated based on MATLAB. The simulation results confirm the correctness of the scheme and control strategies. |
