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.

The exhaustion of the fossil fuel supply of the world is an understood eventuality, considering the pace at which these resources are being exploited the world over. More so when the global energy requirements are increasing without much interruption; suffice to say the current state of operations in the energy arena is not going to last long. Alternative energy resources, in this worldview, provide an auspicious avenue of fulfilling the burgeoning human thirst for energy. The impact of these alternative energy resources utilization will be twofold: the satiation of the energy demand, and the culmination of the global warming resulting from the incessant use of the fossil fuels. The urge for alternative resources of energy is key to survival and demand of future. In comparison to all the alternative resources of energy, Hydro power present better results in terms of efficiency and long term viability.The viability of Hydro Power is subject to its high initial cost and major construction with no return in the initial phase of construction. This work is aimed at presenting the technical and financial aspects of Micro-Hydro power. The financial assessment is based on the Net Present Value (NPV), Internal Rate of Return and Benefit to Cost Ratio (B/C). Apart from the social benefits to the residents and improving the quality of life, the financial feasibility is tested on the basis the above parameters and results shows the micro hydro are feasible in the lights of mentioned parameters. The proposition is tested and implemented on three different case studies, i.e. Ajmera Hydro power plant, Bersa Payen and Sheri Dumrai HPP. The data shows successful results in the all the mentioned cases.

“…As a consequence of increasing population and environmental hazards, the demand for renewable energy is escalating. Wind turbine systems have gained considerable attention for producing green and clean energy, and it is expected that their proportion in production of global energy will increase in the coming decades according to the report of Global Wind Energy Council (GWEC) [3,4]. The characteristics of doubly fed induction generator (DFIG), such as high efficiency, flexible control and low investment cost, make it preferable to be employed in the wind farms.…”

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.
