A New Adaptive Anti-windup Controller for Wind Energy Conversion System Based on PMSG

Abstract

<p>In this paper, an adaptive anti-windup control strategy for permanent magnet synchronous generator dedicated for wind energy conversion systems. The proposed control has the advantage to suppress the performance deterioration caused by the overshooting phenomenon, and optimize the controller gains using the particle swarm optimization algorithm. The scheme of the speed controller is implemented on field orientation control in the generator side converter. A simulation of the proposed scheme is carried out in SIMULINK-MATLAB in order to evaluate the effectiveness of the control against the saturation and the parameter optimization.</p>

Generator and grid side converter control for wind energy conversion system

“…The power coefficient is keeped at its maximum value Cpmax as well as the optimum value of the tip speed ratio. Likewise, mechanical rotational speed Ω must be maintained at an optimum value and vary proportionally with the wind speed V. So, the mechanical reference speed is expressed as: The power extracted by the wind turbine is also maintained at its maximum and it is expressed as shown in: (20) The direct reference current is equal to zero and the q-axis reference current is obtained based as shown in (10): (21) It is indispensable to control the mechanical speed of the turbine blades as well as the currents of the generator to increase the efficiency of the energy transformation. The diagram of the control strategy is presented in Figure 3, which includes two fuzzy blocks.…”

Proposed energy management for a decentralized DC-microgrid based PV-WT-HESS for an isolated community

“…The wind turbine is used for the conversion of kinetic energy, there are many of generators to transfer the mechanical power to electrical power, PMSGs are becoming increasingly popular for wind power applications [14,3], it can generate the electrical power in variable wind speed.The topology that used in this study is ''PMSG direct-driven'' with non-controlled rectifier, associated with a DC/DC converter. The mechanical power obtained by rotor blades is:…”

“…The boost converter has two operation periods. During first period, the controlled switch S1 is ON, while S1 is turned OFF in the second period [14]. The duty cycle formulation of the boost converter is:…”

“…DC/DC Buck-boost converter shown in figure (2-b) is able to generate an inverted output voltage greater than or less than the input voltage, where it operates in the buck mode when k < 0.5 and in the boost mode when k > 0.5 [14]. The duty cycle can be find by…”
