Network loadability maximization by changing the reactance of transmission lines applying Genetic Algorithm and voltage stability considerations

This paper proposed a new method for maximizing the loadability of power networks regardless to the transmission lines compensation types. The paper determines some of the network lines that by making change in the reactance of them, loadability of whole system could rise considerably. This optimized design of mentioned network is performed through Genetic Algorithm (GA) optimization technique. With GA technique, the paper is looking for drastic transmission lines and their compensational values in order to transmitting more power in considered network, provided that maximum loadability of voltage stability besides the minimization of costs is respected sufficiently. Numerical results are obtained applying IEEE-39 Bus test system as a case study for testing correctness and applicability of this new offered solution.
