Meta-Heuristic Algorithms Based Active Power Loss Minimisations

This manuscript presents integrated evolutionary approaches to minimise the real power losses in a given power-system network to improve the system performance and to reduce the overall cost of power transmission. The integration of the Genetic Algorithm and hybridised Simulated Annealing with Pattern Search are proposed and applied to determine the optimum adjustments to the control variables. The approach satisfies and maintains the equality and inequality constraints. The proposed method is applied to many test systems with different operating scenarios. The numerical test results and simulations with different load patterns and single line outages were demonstrated and analysed. The effects of changing the control variables were studied and investigated as well. The results obtained show the effectiveness, flexibility, and applicability of the proposed integrated approaches for power loss minimisations by considering the overload condition of lines with high accuracy and within somehow an acceptable computational time.
