In this paper, a method for minimization of Total Harmonic Distortion (THD) is proposed in case of PWM inverter. Inverters are widely used in many applications such as in the UPS and ac motor drives resulting in harmonics production. A phase compensation Resonant Controller (RSC) is proposed for 1-phase pulse width modulation (PWM) inverter using MATLAB simulation. The simulation results are th...

In this paper we aim to address the problem of dynamically dispatching a group of state-of-the-art deloaded wind generators (WGs) in a fair-sharing manner. We use the term dynamically since the WGs aim to dispatch themselves according to a varying committed WF power output. We first propose a leader-follower protocol whose execution guarantees asymptotically, two control objectives. These are 1...

This paper presents Maximum Power Point Tracking (MPPT) controller design of Doubly Fed Induction Generator (DFIG) using Genetic Algorithm (GA). Essential feature of proposed controller is that it is used to trace the maximum power when wind speed is lower than the rated wind speed. Doubly-Fed Induction Generator DFIG has stator terminals are connected directly to the grid. However, the rotor t...

Abstract To suppress the subsynchronous oscillation in doubly-fed induction generator (DFIG) system with Static VAR Generator (SVG), a feedback linearization control (FLC) method for rotor-side converter (RSC) is proposed, and its effect under small disturbances analyzed verified. Firstly, 22-order time-domain model of DFIG SVG established. Secondly, combined principle linearization, correspond...

Extensive use of wind turbine (WT) systems brings remarkable challenges to the stability and safety power systems. Due difficulty complexity modeling such large plants, model-independent strategies are preferred for control WT plants which eliminates need model identification. This current work proposes a novel methodology in rotor side converter (RSC) part ameliorate low voltage ride through (...

A Recursive Switched-Capacitor (RSC) topology is introduced that enables reconfiguration among conversion ratios while achieving minimal capacitive charge-sharing loss for a given silicon area. All ratios are realized by strategically interconnecting 2:1 SC cells either in series, in parallel, or in a stacked configuration such that the number of input and ground connections are maximized in or...

This paper presents a design of pitch controller using Genetic Algorithm (GA) for variable speed wind turbine Doubly Fed Induction Generator (DFIG) . The proposed genetic pitch controller is used to get the proper pitch angle for limiting the mechanical power when the wind speed is greater than the rated wind speed. DFIG is a wound-rotor induction generator where the stator terminals of DFIG ar...

The low voltage ride-through (LVRT) capability of the doubly-fed induction generator (DFIG) significantly impacts upon the integration of wind power into the power grid. This paper develops a novel comprehensive control strategy to enhance the LVRT and reactive power support capacities of the DFIG by installing the energy storage system (ESS). The ESS is connected to the DC-link capacitor of th...

A novel control strategy is proposed in this paper for the rotor side converter (RSC) of doubly-fed induction generator (DFIG)-based wind power generation systems. It is supposed to enhance the low-voltage ride-through (LVRT) capability of DFIGs during great-level grid voltage dips. The strategy consists of a proportional-resonant (PR) controller and auxiliary PR controllers. The auxiliary cont...
