“…These variable-speed wind plants are decoupled from the corresponding electricity grid by power electronic converters. Different from synchronous generators, some types of wind plants are not able to play a part in frequency control activities such as inertia and governor response after a disturbance [33][34][35][36][37]. Although several control methodologies have been developed to allow Type-3 and Type-4 wind plants to be used for frequency regulation [38,39], such solutions are still not mandatory and normally do not operate for the Type-3 wind plant.…”

Installing a synchronous condenser (SC) onto an electricity grid can assist in the areas of reactive power needs, short-circuit strength, and, consequently, system inertia and guarantees better dynamic voltage recovery. This paper summarizes the practical potential of the synchronous condenser coordinated in an electric-power network with participating wind plants to supply reactive power compensation and injection of active power at their point of common coupling; it provides a systematic assessment method for simulating and analyzing the anticipated effects of the synchronous condenser on a power network with participating wind plants. A 33-kV power line has been used as a case study. The results indicate that the effect of the adopted synchronous condenser solution model in the MATLAB/Simulink environment provides reactive power, enhances voltage stability, and minimizes power losses, while the wind power plants provide active power support with given practical grid rules.

“…A wind turbine operates on a particular site according to the design parameters, cut-in wind speed, cut-out wind speed and rated power are selected according to the location of wind characteristics. Wind turbine efficiency is not dependent upon the characteristics of wind site but on wind speed distribution [49], [52]. It is found that the maximum efficiency of a wind turbine is 59 %.…”

The increasing environmental awareness across the globe is leading towards a green and clean world. Currently, Pakistan is going through an acute energy crisis; it is an ongoing challenge for the government to provide uninterrupted power supply at economical rates to its citizens and potential industrial investors, now and in future. Thus, this energy scenario necessitates the incorporation of renewable energy technologies with power systems to enhance its generation capacity, and to overcome electricity outage of approximately 8-12 hours, in the country. In this paper, the authors encouraged the state policy for utilizing the wind energy for power generation, which is freely available across 1600 km long coastal belt of Pakistan. For this purpose, wind potential is explicitly evaluated across Sindh and Baluchistan provinces in Pakistan. The energy generated by various wind turbine prototypes is employed to suggest the most optimum location through optimal probability function. Moreover, this study provides an evocative progression based on realtime wind data to integrate wind power for rural electrification across the coastal zones of Pakistan. This study is expected to play an imperative role in incorporating wind farms on proposed sites to facilitate investors interested in investing in Pakista's energy sector.

“…When the rotor speed is closer to the synchronous frequency, the system possesses a higher bandwidth for feedback stator flux. Multiple-input and multiple-output (MIMO) system of state feedback linearization control is described in [38][39][40][41][42]. However, the foremost intention of feedback linearization is to transform nonlinear models into linear ones and it is the most authentic approach for handling practical nonlinear control designs.…”

This paper primarily focuses on an advance control strategy to enhance the low voltage ride through (LVRT) capability in doubly fed induction generator (DFIG) based wind energy conversion system (WCES). In the proposed control strategy, the captured wind energy during grid faults circumstances is stored timidly in the rotor’s inertia kinetic energy. Though a minimal amount of energy is available in the grid, stator current and DC-link voltage are set beneath the perilous levels. However, both the required stator voltage and stator current are kept within a tolerable range of rotor side converter (RSC), through state feedback linearization technique for maintaining the accurate control to suppress the overvoltage and overcurrent. Furthermore, stator current oscillations are significantly suppressed during fault transient. The input mechanical energy from the wind turbine can be resumed after the fault clearance. In spite of being dissipated in the resistors of crowbar circuit, as in the conventional LVRT assemblies, torque balancing among electrical and mechanical measures is attained; DC-link voltage instabilities and rotor speed inconsistencies are substantially reduced. As a result, a noticeable reduction in the requirement of reactive power and swift restoration of terminal voltage on fault clearance is acquired successfully. Correspondingly, several tests are conducted to validate the effectiveness and enhancement in the performance of the DFIG based wind farms, when the proposed control strategy is implemented over it during numerous fault ride-through circumstances.
