Transmission network congestion is an important issue in deregulated power systems, whenever the physical or operational constraints in a transmission network become active, the system is said to be in a state of congestion. Congestion management (CM) is a mechanism to prioritize the transactions and commit to such a schedule that will not overload the network. This paper presents relieving tra...

The optimal power flow issue (OPFI) can be solved in this work using the recently developed algorithm, gorilla troops algorithm (GTA). goal of OPFI is to reduce numerous functions such as minimizing fuel costs, emissions, and losses improving voltage stability related electric networks (EPNs). GTA inspired by gorillas’ social habits, which include migration a strange region, toward specified sp...

Recently, genetic algorithms (GA) and particle swarm optimization (PSO) technique have attracted considerable attention among various modern heuristic optimization techniques. Since the two approaches are supposed to find a solution to a given objective function but employ different strategies and computational effort, it is appropriate to compare their performance. This paper presents the appl...
