This paper proposed switched fractional order controller (SFOC) for grid connected Wind Energy Conversion System. The SFOC consists of conventional PI controller, fractional order IP controller and decision maker. The SFOC controller is applied to control PMSG connected to the grid. The proposed control aims to extract maximum power under fluctuating wind speed. SFOC controller designed to solve the...
A novel controller is proposed to regulate the DC-link voltage of a single phase active power filter (SPAPF). The proposed switched fractional controller (SFC) consists of a conventional PI controller, a fractional order PI (FO-PI) controller and a decision maker that switches between them. Commonly, the conventional PI controller is used in regulation loops due to its advantages in steady-state but...
This paper integrates a suitable controller in DC-bus voltage regulation loop of the direct current control (DCC) algorithm for three-phase grid-connected PV system. The proposed controller named fractional order PI (FO-PI) controller adjust the integration order from integer to real value. The FO-PI controller provides a faster settling time and stands the parameters variation and the external disturbances...
This paper deals with implementation of Direct Power Control (DPC) using conventional PI controller applied to shunt active filters (SAPFs) using new parameters. The PI controller regulates the DC-link voltage, active and reactive power-flows of the power filter. The steady state and dynamic behavior are presented and illustrate the operation and the performance of the system. Simulation and experiment...
This paper presents a simulation of PV system (PV panel, boost inverter and a resistance load) using M-file of MATLAB, To prove the efficiency of this system we applied two method of MPPT in the global algorithm, one classical and the other one is intelligent: the first one is called Perturbation and observation (P&O) used in stand-alone places or in simple installation and the later is based...
Fractional order direct power control (FO-DPC) has been proposed in this paper, this command applied to active power filters (APFs) with fractional PI regulator to control DC-bus voltage of the capacitor, this active configuration of APF allows us to control the active and reactive power and compensate the harmonics of current. The static and dynamic behavior of DPC and FO-DPC are presented to prove...
This paper presents a comparative study between P&O and sliding mode (SM) algorithm to track the maximum power of a PV panel using M-file of Matlab. To prove the efficiency of the proposed controller, these two MPPT in the global algorithm, one classical and the other one is intelligent. The different steps of these controllers design are presented together with their simulation. In one hand the...
Photovoltaic electricity is seen as an important source of renewable energy. The photovoltaic array is an unstable source of power since the peak power point depends on the temperature and the irradiation level. This paper presents a simulation of PV system (PV panel, boost inverter and a resistance load) using MATLAB. To prove the efficiency of this system we applied two methods of MPPT. The different...
