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.

This paper presents a robust control strategy for a grid connected photovoltaic system with a boost converter by using an integral Backstepping method based on a nonlinear state model, which guarantees the Lyapunov stability of the global system. The system has tracked precisely the maximum power point, with a very fast response and the unit power factor has been observed under different atmospheric conditions. Moreover, the best advantage of the controller is that it’s a good corrector of the grid perturbation and system parameter disturbance. The simulation result has demonstrated the performance of this strategy.

This paper presents a new control strategy of a photovoltaic system, which consists of a photovoltaic generator PVG coupled to a three phase load and three phase grid by a three phase voltage source inverter VSI without DC-DC converter. The controller is designed by using Backstepping method based on d-q transformation of a new model of the global system. The main goals of this control strategy are to achieve the maximum power point MPPT with very good precision and the unity power factor in level of the grid power flow. Mathematical analysis demonstrate the asymptotic stability of the controlled system and simulation results proved that the controller has achieved all the objectives with high dynamic performance in presence of atmospheric condition changes. Moreover, the proposed controller shows a very good robustness under system disturbance, which presents the most important advantage of this controller compared to the other control strategies. Furthermore, this controller can operate with a high efficiency with any kind of the load.
