The adoption of renewable energy sources, particularly wind energy, has seen remarkable growth in recent years. Wind energy generation requires efficient and reliable generators that can convert wind energy into usable electrical energy. Switched Reluctance Generators (SRGs) have been gaining popularity in wind energy applications due to their high efficiency, reliability, and low maintenance requirements. The multiphase switched reluctance generators are used especially in wind power plants due to their ability to operate in variable speed ranges. In this paper, a MATLAB/SIMULINK based model of Switched Reluctance Generator (SRG) is presented. The obtained results show good agreement under different operating conditions. The obtained results (current, voltage, torque, speed, flux, and angle of generator) are shown in graphs. [ABSTRACT FROM AUTHOR]

Since the consumption of non‐renewable sources is diminishing day‐by‐day, most of the developing countries across the globe are facing a severe energy crisis. This energy crisis affects the developing countries such as Pakistan so extensively that population has a crucial problem of load shedding for long hours. Thus, there exists a fundamental need for alternative and economical energy resources, for example, solar, wind, and biofuel energy. Meanwhile, out of all the financially viable ways of power generation, the wind energy is considered as the most economical way. However, in this article authors selected six potential wind zones which lie within 1100 km of coastal zones. In this study, only 1‐year wind speed raw data is considered and taken from appropriate wind zones at various heights with the support of Pakistan Metrological Department. Besides all, this project encourages the domestic as well as the foreign investor to invest in the wind energy projects at windy zones, which basically opens the business doors for the community of Pakistan for power generation, which leads to overcoming the energy crisis along the countryside. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 706–720, 2019 [ABSTRACT FROM AUTHOR]

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.
