<p>This paper presents a grid-connected photovoltaic system (PV) used as a shunt active power filter (SAPF) to provide the power factor correction, harmonic elimination, reactive power compensation and to simultaneously supply power from a PV system to the utility. A direct power control (DPC) method is used for controlling the system to feed the photovoltaic energy in synchronization with grid and provide power quality improvement. The PI parameters of DC-link voltage controller are tuned using the Particle Swarm Optimization (PSO) algorithm without the need for an exact mathematical model of system. This PI-PSO controller gives better results for robustness, harmonic minimization and reduces the overshoot and undershoots of PI controller. The overall control of system is tested in Matlab/Simulink environment. Then, the simulations results demonstrate the robustness and feasibility of proposed method.</p>

“…Switching Table Vdc Comparing the instantaneous active power (P) at a reference power (P ref ), this latter is obtained by the DC voltage control block at the capacitor terminals, where we use a PI controller (Proportional, integrator) tocontrol the error between the sensed voltage (continuous) and reference [18], [20], [21]. Whilst to achieve a unity power factor, reactive power reference is directly imposed zero (Q ref =0).…”

This article describes firstly a wind power production line, principally a wind turbine constitutes her and brushless doubly fed induction generator (BDFIG). The models of these components are developed, and control objective of BDFIG is to achieve a dynamic performance similar to the doubly fed induction generator (DFIG) using a stator flux field oriented control (FOC) and direct power control (DPC) strategy. After, the simulation program using Matlab/Simulink has been developed. The performances of this strategy are evaluated and analyzed, so the results shows a good robustness great dynamic and a precision of speed.

“…The main idea of the direct power control (DPC) originally proposed by Ohnishi (1991) and further developed by Noguchi et al in 1998, is similar to the direct torque control (DTC) of induction machines. Instead of flux and torque, the active power ( p ) and reactive power ( q ) are selected as two instantaneous magnitudes to control (figure 5), [10].…”

In this study, we present a new control method entitled direct power control without voltage sensors of a grid connected photovoltaic system associated with an active power filter. The direct control of power (DPC) is employed for the calculation of reference current generation. In this technique the switches states of inverter are selected from a table of switching based on the immediate errors between the active and reactive powers and their reference values. The objective of this paper is the reduction of Total Harmonic Distortion (THD) of source current, compensate reactive power and inject the maximum active power available from the PV array into the load and/or grid. Matlab/Simulink simulations are provided to demonstrate the performance of the proposed approach.
