Development of constrained-genetic-algorithm load-flow method

A genetic-algorithm load-flow algorithm is developed. Methods for satisfying the power balance requirement and the voltage magnitude constraint are then developed and incorporated into the genetic-algorithm method to form a constrained-genetic-algorithm load-flow algorithm for solving the load-flow problem. The robustness of the new load-flow algorithm is enhanced by the dynamic population method, the technique for accelerating the convergence of the optimisation process and the network node sequencing procedure described in the paper. The paper presents study results obtained by applying the new algorithm to study the practical Klos-Kerner 11-busbar system under light-load and heavy-load conditions.
