| description | In order to reduce the complexity of photovoltaic generation system, a direct power model predictive control method suitable for DC-side sensor-less photovoltaic inverters is presented in this paper. Based on the idea of serial calculation, each H-bridge is considered as a single inverter. In the meantime, when the optimal modulation function is being calculated for each H-bridge, the DC-side capacitor voltage of each H-bridge is reconstructed using the increment of output voltage of inverters. In addition, a term about the error of capacitor voltage is embedded into the optimal modulation function to keep capacitors’ voltages balance. After building a system model through Matlab/Simulink, the performance of the presented method is verified. |
