Dynamic Modeling and Simulation of Photovoltaic Energy Conversion System

The use of new efficient photovoltaic (PV) solar cells has emerged as an alternative measure of renewable green power, energy conservation and demand-side management. The power generated by a PV cell depends on the operating voltage of the array; its voltage-current and voltage-power characteristic curves specify a unique operating point at which maximum possible power is delivered and the array is operated at its highest efficiency. In this paper, dynamic modeling and simulation of photovoltaic energy conversion system (PVECS) is presented. The maximum power point tracking (MPPT) control for PVECS is also addressed in this paper. The whole system has been developed and simulated using Matlab/Simulink environment. Simulation studies have been carried out to verify the system performance. The results show that the overall power management strategy is effective.
