This paper focuses on a renewable energy system connected to a dual-function power grid through a parallel active power filter for simultaneously injecting photovoltaic energy to the grid and improving the power quality in the presence of the non-linear load. The rejection of disturbances affecting the grid is offered by the improved direct power control (IDPC).This command includes an anti-windup fractional order proportional-integral differentiator (AW-FOPID) regulator, which replaces the traditional PID or PI controllers to maintain the DC bus voltage at its reference value with small undershoots and overshoots in the voltage, while maintaining a short response time. However, the suggested regulator has five parameters, making it difficult to adjust. Therefore, the Particle Swarm Optimization with the spreading factor (PSO-SF) technique is used to tune this AW-FOPID parameters by minimizing the objective function. On the other hand, an intelligent method based on fuzzy logic was used to track the maximum power point (MPPT)under any weather conditions. and to solve the problem of the rapidly changing irradiance. The proposed system control is evaluated in various states of power source: distorted, unbalanced and balanced by simulation using MATLAB/Simulink. The obtained simulations results demonstrate the performance of the studied control strategies.
