Off-grid Photovoltaic (PV) system along with battery storage is very effective solution for electrification in remote areas. However, capacity selection the most challenging task designing. In this study, an off-grid PV designed area of Karachi, Pakistan. The by considering maximum energy requirement summer season. selected to fulfill demand during night and cloudy seasons. On basis load, a total 6 kW required demand. For such system, 925 Ah meet day absence solar irradiation. A...
Organic Rankine Cycle (ORC) is an attractive option to utilize the low-grade waste heat for power generation. The selection of working fluid ORC a challenging task because environmental constraints as most organic fluids has capacity damage environment. In this research, method optimum operation low grade determined. depends upon thermal efficiency, Global Warming Potential (GWP), Ozone Depletion (ODP) and Atmospheric Lifetime fluid. Twelve different including R134a, butene, R22, R152a,...
With the increase in electricity usage through developing countries, financial crises has enveloped due to energy poverty. Issues such as circular debt are now a major factor that drastic impact on economic condition of countries. Power sector, being constituent structure role play for changes condition. This paper numerically evaluates challenges power sector and inevitable shortcomings policies with growing debt. The case study been performed Pakistan solutions proposed mitigate this...
The performance of a wind turbine depends on its first law efficiency and second efficiency. This study focuses the efficiency, that is, exergy turbine. introduces novel technique for determining optimum conditions Jhimpir City, Pakistan, was selected case study. speed distribution in area analyzed using different probability density functions. three-parameter Weibull is best function fitting variation. total performed, one-year variation plotted, showing maximum around middle year. power...
