A Discrete Bat Algorithm Based Optimal Location and Sizing of Power Distribution Substation

Ibrahim Mohammed Manga^*, Adamu Abubakar Sa’idu, Ismaila Mahmud, Mahmud Mustapha, Abdullahi Abubakar, Ibrahim Bashir Shehu

Distribution substation planning is considered one of the most important steps in the power system planning process. A planning model seeks to determine a strategy that will minimize losses and total costs associated with configuring and operating an electric power distribution system over a given planning horizon. Metaheuristic methods are usually deployed in solving the distribution planning pro...

APPLICATION OF WHALE OPTIMIZATION ALGORITHM (WOA) FOR DISTRIBUTION NETWORK RECONFIGURATION SCHEME FOR POWER QUALITY IMPROVEMENT

A Bukar^*, G. A. Olarinoye, Y. Jibril

Electrical power distribution networks (DN) are usually designed and operated in a radial configuration, but their topology, especially when highly loaded, is often meshed in order to improve system reliability and quality of the supply. This makes it feasible to alter the network topology after an outage to restore the service to affected areas. In addition, various power quality indicators can b...
