Abstract: Electrical Power System Expansion Planning (EPSEP) is a critical process in ensuring that electricity supply meets future demand in an economically viable, reliable, and environmentally sustainable manner. It involves long-term planning for generation, transmission, and distribution infrastructure to accommodate growing loads while optimizing operational costs and maintaining system reliability. The increasing integration of renewable energy sources, advancements in smart grid technologies and evolving environmental regulations have added complexity to EPSEP. This paper provides a comprehensive analysis of strategies, optimization models, and decision-making approaches for effective power system expansion planning. Challenges such as uncertainties in demand forecasting, renewable energy intermittency, and financial constraints are discussed, along with solutions leveraging advanced computational techniques. The study also highlights case studies and simulation-based approaches for improved accuracy in planning outcomes.
Keywords: Electrical power system, expansion planning, optimization, generation capacity, transmission planning, renewable integration, reliability, smart grid.
