Abstract


The problem of power shortfalls in Pakistan has had a severe impact on the industrial and agricultural growth in the country. Furthermore, it affects how people there perform their daily lives. This problem has existed over the last 30 years, and the shortage between supply and demand has almost exceeded 7.2 GW at the peak time in 2016. To avoid this continuous imbalance between supply and demand, load shedding is carried out daily, mainly to maintain system stability and to avoid complete blackouts. The electricity demand has grown at a rate of more than 5% annually in Pakistan, which means greater challenges in meeting future demand. This paper suggests a novel experimental load shedding strategy for solving the existing power grid issues. As a case study, the proposed strategy has been applied to the Peshawar Electricity Supply Company (PESCO). The proposed method overperformed the existing load shedding scheme in terms of minimizing the load shedding time with the least economic impact. The proposed system has a cost-effective design based on the existing grid infrastructure with minimum system upgrade requirements.
