In this paper, it is proposed a robust Second-Order Super-Twisting Sliding Mode Control for a Grid-connected inverter of a PV power plant. The proposed control strategy is able to maximize the energy extracted from the PV while regulating the DC-link voltage and achieving a power factor compensation and the reduction of currents harmonic distortion. Both in balanced or unbalanced condition, the grid...
The paper deals with a Second Order Variable Structure Control (VSC) for Wind Turbine PMSG-based and Generator-side Converter System. By means of the proposed control and the associated sliding observer, a vectorial control of PMSG generator is recognized while maximum power point tracking by the renewable source and DC voltage control of the generator-side converter are assured to maintain a high...
In this article, a current control algorithm is conceived for converting solar dc power into ac power of high-quality. This conversion is based only on a dc-ac converter, avoiding the use of two stage converter. The proposed algorithm is founded on tracking the maximum power point which ensures controlling the electrical power exchanged with the grid. To assure a good dynamics and reduce the control...
