“…However, the impact of the load shedding on the long-term basis can be catastrophic for the countries as it severely affects their economic growth. According to the World Bank, regular electricity shortages have badly hurt the economy of several nations, including Pakistan, Sri Lanka, South Africa and India [ 5 ].…”

This paper demonstrates the application of hybrid energy system (HES) that comprises of photovoltaic (PV) array, battery storage system (BSS) and stand-by diesel generator (DGen) to mitigate the problem of load shedding. The main work involves techno-economic modelling to optimize the size of HES such that the levelized cost of electricity (LCOE) is minimized. The particle swarm optimization (PSO) algorithm is used to determine the optimum size of the components (PV, BSS). Simulations are performed in MATLAB using real dataset of irradiance, temperature and load shedding schedule of the small residential community situated in the city of Quetta, Pakistan. The LCOE for the HES system under study is 8.32 cents/kWh—which is lower than the conventional load shedding solution, namely the uninterruptable power supply (UPS) (13.06 cents/kWh) and diesel and generator system (29.19 cents/kWh). In fact, the LCOE of the HRES is lower than the grid electricity price of Pakistan (9.3 cents/kWh). Besides that, the HES alleviates the grid burden by 47.9% and 13.1% compared to the solution using the UPS and generator, respectively. The outcomes of the study suggests that HES is able to improve reliability and availability of electric power for regions that is affected by the load shedding issue.

“…In addition, rapid population growth and the lack of investment in power infrastructure (including national grid) add to further stress on the system. As a result, grid operators are forced to resort to load shedding to sustain the system at its current level [2]. Load shedding is a power system control procedure intended to reduce or limit a specific amount of electrical load when the demand for electricity surpasses the supply capacity of the network [3].…”

Given the significant impact of the UN 2015 agenda on sustainable development, the search for eco-friendly and efficient energy solutions has intensified. The renewable based hybrid systems have emerged as feasible solution in this regard. This paper investigates the prospect of utilizing hybrid energy system (HES) from a different perspective, i.e., to mitigate the effect of load shedding at the distribution level. The HES configuration in this study includes photovoltaic (PV) array, wind turbine (WT), battery storage unit (BSU) and diesel generator. The optimization of HES has been performed based on levelized electricity cost (LEC), payback period (PBP) and loss of power supply probability (LPSP). The Grasshopper optimization algorithm (GOA) is employed to determine the optimum number of PV modules, WT, and BSU using load-following power dispatch strategy and the results are verified with particle swarm optimization algorithm (PSO). The performance of the optimized HES is tested in a small residential community in Quetta, Pakistan, which frequently experiences load shedding. The results of optimized HES ensuring supply availability provide minimum LEC and PBP as 6.64 cents/kWh and 7.4 years, respectively. These results are compared with conventional solutions such as standalone diesel generators, battery-based uninterruptible power supplies (UPS), and hybrid systems combining generators and UPS. The findings show that HES significantly outperforms conventional solutions. Finally, the research presents sensitivity analysis, examining the impact of varying component prices, feed-in tariff rates, meteorological conditions, and load demand variations on the LEC and PBP of the HES.INDEX TERMS Optimization, renewable, photovoltaic, wind turbine, power outage, multi criteria, feed in tariff I.
