Application of Jaya and PSO Algorithms for Optimal Sizing of Renewable Energy Sources in Power Systems
Abstract: The deregulation and privatization of the electrical sectors in recent years have caused the distribution systems to run closer to their load capacity limit. Due to the increased power loss resulting from this, the distribution system now operates at a higher voltage than the current transmission networks. For electric power system networks to be more reliable, efficient, and cost-effective, distributed generation must be positioned and sized optimally. Allocation helps minimize …
