Electricity access plays a key role in defining the socio-economic status of a community. Millions of people around the globe are suffering from energy poverty, particularly the inhabitants of rural areas of developing countries. Pakistan is one of those countries which are suffering from electricity shortage and extreme load-shedding. In this paper, a hybrid microgrid system is designed across the eastern route of China–Pakistan Economic Corridor (CPEC) using renewable energy sources (RES). The design and simulation of the proposed microgrid are through Hybrid Optimization Model for Electric Renewables) HOMER software, developed by National Renewable Energy Laboratory (NREL) [1]. The rural areas near Sukkur, Nawabshah, and Hingorja are chosen for the design of the microgrid system. The source energy profiles for solar, wind, and temperature are taken from the online database of National Solar Radiation Database [2], National Renewable Energy Laboratories (NREL) [3], and National Aeronautics and Space Administration (NASA) Surface Meteorology and Solar Energy [4] respectively. Due to the intermittent nature of renewables, diesel generator and energy storage are used as a backup. The cost optimization of the system is performed using HOMER with least cost of energy (LCOE) and net present cost (NPC) as the decision variables. Additionally, sensitivity analysis, techno-economic analysis, and cost analysis are performed to test the designed system.

Recently, the Li-Ion batteries are extensively employed. To assure effective battery utilization the Battery Management Systems (BMSs) are used. Recent BMSs are becoming sophisticated and consequently cause a higher consumption overhead. To enhance the BMSs effectiveness, this work employs event-driven sensing and processing. In contrast to the traditional counterparts, the battery cell parameters are no more captured periodically but are acquired based on events. It results in significant real-time data compression. Afterward, this non-uniformly partitioned information is employed by an original algorithm for a real-time determination and calibration of the cell State of Health (SoH). The devised system comparison is made with the traditional counterparts. Results demonstrate a more than third-order of magnitude outperformance in terms of compression gain and computational efficiency while assuring an analogous SoH estimation precision.

The Power quality (PQ) disturbances originates problems in smart grids and industries. The identification and prevention of such disturbances is mandatory. This paper suggests an original approach, based on event-driven processing, for time-domain PQ signals features extraction and recognition. The incoming PQ signal is digitized with an event-driven A/D converter (EDADC). A novel selection mechanism is employed to efficiently segment the EDADC pertinent output. Later on, features of these segments are explored by performing only the time-domain analysis. The identification is performed with a specifically developed voting based classifier. Results demonstrate a first order of magnitude reduction in collected samples as compared to the traditional counterparts. It aptitudes a significant processing and power consumption effectiveness of the designed solution compared to the counterparts. The proposed system attains an average recognition accuracy of 98.06%, for the case of a three class PQ disturbances. It demonstrates the benefit of embedding the proposed solution for the development of effective automatic PQ disturbances recognizers.

Small-scale hybrid solar-wind energy generator system offers a feasible alternative for decentralized power generation compared to large-scale wind or solar farms remotely installed at various wind and solar energy, rich sites across Pakistan. These sites require dedicated power transmission lines in order to connect the electric power generated by these wind or solar energy farms to the national grid. The manufacturing, operation and maintenance costs of small-scale hybrid i.e. vertical-axis wind turbines (VAWT) and solar system, are low, consequently, making them ideal for rural and urban environments. In this work, a small-scale light weight, modular of hybrid solar-wind prototype of 400W rated capacity is designed and manufactured that will produce 200W power through wind turbine and 200W power from solar system. The prototype comprises 03 blades of rotor, made of glass fiber reinforced plastics (GFRPs) composites using vacuum-assisted resin transfer molding (VRTM) process to lower its weight and one number of solar panel as per design requirement. For the rotor blades of turbine, a relatively thick and symmetric air foil of type NACA0021 is used to overcome its self-starting deficiency. The generator part is also made of epoxy resin system to reduce cogging torque between the permanent magnets and stator. In addition, the hybrid solar-wind energy generator system is integrated with local energy (WAPDA) available in domestic level of provinces of Pakistan. Furthermore, prototype testing will be conducted to quantify its efficiency and effectiveness as well as to identify its limitations.

The performance characteristics of vertical axis wind turbines are considerably influenced by dynamic stall phenomenon which is the processes of delayed flow separation caused by a rapid excursion in the angle of attack of rotating blades. It leads to a sudden drop in lift forces which further reduce the rotor power output and efficiency significantly. The present analysis is to explore the ideas for enhancing the performance and efficiency for a vertical axis wind turbine model by implementing leading-edge slat on blades of the turbine to delay flow separation. In this paper a comprehensive two-dimensional computational fluid dynamics study has been carried out on airfoil under transient pitch oscillating motion, to obtain detailed flow fields for analysis and flow visualization. The Reynolds Averaged Navier-Stokes K-omega shear stress transport model is used to predict turbulence during computations. In addition, a sliding mesh technique along with the user-defined function is used. The outcomes show that the improved design of the turbine with the leading edge slat not only increases the lift coefficient at low Reynolds number but also enhanced the capability of wind energy extraction compared baseline model. The flow separation was delayed by a certain degree due to the leading edge slat. Consequently, the proposed model is appropriate and it can be used various lifting objects, to enhance the output power and efficiency.

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.
