“…Super-twisting algorithm, called higher-order sliding mode of the second order, has been adopted to achieve maximum wind power tracking and reactive power regulation [14][15][16][17][18][19]. However, control gains for these schemes cannot be real-time adjusted along with variation of system uncertainty.…”

This paper proposes an adaptive gain second-order sliding mode control strategy to track optimal electromagnetic torque and regulate reactive power of doubly fed wind turbine system. Firstly, wind turbine aerodynamic characteristics and doubly fed induction generator (DFIG) modeling are presented. Then, electromagnetic torque error and reactive power error are chosen as sliding variables, and fixed gain super-twisting sliding mode control scheme is designed. Considering that uncertainty upper bound is unknown and is hard to be estimated in actual doubly fed wind turbine system, a gain scheduled law is proposed to compel control parameters variation according to uncertainty upper bound real-time. Adaptive gain second-order sliding mode rotor voltage control method is constructed in detail and finite time stability of doubly fed wind turbine control system is strictly proved. The superiority and robustness of the proposed control scheme are finally evaluated on a 1.5 MW DFIG wind turbine system.

“…The objective of our study is to ensure the control and continuation of the trajectory of the reference yr by the output y of the system, thus making the error e=yr-y tends towards zero in the presence of uncertainties and disturbances. For this, the sliding surface will be used to calculate the sliding variable can be rewritten as follows [21]:…”

This paper deals with the problems of intermittency of primary source of wind energy and the external disturbances. Subsequently, a power management and a robust control of a standalone energy production unit are presented. This production unit comprising a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) and a module of Super-Capacitors (SC) that is considered as an Energy Storage System (ESS). This unit feeds a three-phase load by means of an inverter and an RLC filter. In order to assure a control strategy which has a very good performance despite the high nonlinearity of wind systems and an intermittence form of wind power, a second-order sliding mode control based on a super-twisting algorithm is applied to a PMSG. Then, a power management strategy is applied to the SC using a buck-boost converter according to load instructions and wind speed fluctuations. The response of the power algorithm enables to ensure the power flow exchange between the production unit and the power consumers and to protect the ESS against overcharge and excess discharge to ensure safe operation. Finally, using PI controllers, the inverter adjusts the capacitors voltages and currents at the output of the RLC filter with the nominal frequency and voltage. The simulation results show the robustness of the implanted control strategy.

“…Off-shore wind power generation is cumbersome for researchers in this field. The large and medium capacity find farm which is connected to transmission lines has so many tedious problems because of unpredictable nature of wind [3], [4]. Hence power output from wind generator can be controlled by controlling voltage, frequency, real power control, reactive power, fault ride through.…”

Nowadays, fossil combustibles are replaced by renewable energy sources. These renewable energies are nontoxic, dirt free, protected and reasonably cheap for the end-users. Renewable energy resources like bio-gas, geothermal, solar, tidal waves and wind have been found as the best alternative energy sources. Among these renewable energy sources, wind energy stands first and foremost for generating electricity.In order to have a constant utilization of wind energy maximum power from wind energy has to be extracted. In this paper, various control strategies prevalent to both the Doubly Fed Induction Generator (DFIG) and Permanent Magnet Synchronous Generator (PMSG) have been analyzed. In addition, control topologies applicable to power electronics converter/inverter used in wind electric generators are discussed.
