Abstract

This paper presents a new model and an advanced control strategy of a three phase grid connected photovoltaic system without DC-DC converter. The novel model is characterized by decoupled inputs and high relative degree of the outputs. A sliding mode control without chattering phenomena based on this new model is applied in order to control the system to track the maximum power point produced by the photovoltaic generator PVG, convert all this power to active power and compensate the harmonic components and reactive power caused by nonlinear load if it is connected to the PV system. This controller is able to realize all these objectives with a high dynamic performance in presence of changing atmospheric conditions, system’s disturbance and with any kind of load or without load. Simulation results demonstrate efficient performance and robustness of the proposed strategy.
