Design and Analysis of hybrid power generation system for Rural Electrification. A case study

Nature has blessed Pakistan with immense Renewable Energy potential. The efficient utilization of renewable resources can contribute to overcome electricity shortfall in Pakistan. Electricity can be locally generated from distributed energy resources and can be locally distributed through microgrids. This research presents a design of microgrid with hybrid power generation system for a Post Graduate collage and its hostels, located in district Karak of Pakistan. Solar and wind are considered the feasible energy resources for the selected site. Two different systems are designed. One system has only renewable resources, while other has a backup diesel generator because of intermittence resources. Both of the systems are simulated for the specific load profiles of campus and hostel buildings and optimized results are obtained from HOMER (HOMER stands for Hybrid optimization Model for Multiple Energy Resources). A comparative analysis of both systems is done with respect to the cost, installation capacity and annual emissions.
