This paper considers a three-phase grid-connected photovoltaic (GCPV) system, which comprises a 120kW PV farm connected to the grid through a step-up transformer. GCPV is considered as a distributed generation (DG) serving a variable local load (LL) connected to the low voltage side of the transformer. A power conditioning unit (PCU) consisting of a two-stage energy conversion device is used to (i) maximize the extracted PV farm output power, and (ii) control power exchange with the grid. The PCU regulates the LL voltage level by means of reactive power compensation (RPC). The proposed system is equipped with an intelligent energy harvesting method based on particle swarm optimization-subgradient algorithm (PSO-SG). It is shown that the system operates efficiently using the proposed PCU. Validation of the model has been carried out by using MATLAB/Simulink.
