Reactive power and voltage control using micro-genetic algorithm

In the paper, a micro-genetic algorithm (MGA) based approach to the optimization of reactive power and voltage profiles improvement and real power loss minimization is present. The proposed strategy aims to prevent voltage fluctuations and unconvergence cases by coordinating the operation of reactive power and voltage control equipments. The problem is formulated as a combinatorial nonlinear optimization problem. Genetic algorithms (GA) are well-known global search technique anchored on the mechanisms of natural selection and genetics. Because of the time intensive nature of the conventional GA, the MGA is proposed as a more time efficient alternative. The feasibility and effectiveness of the developed algorithm is tested and verified on the Hunan grid power system.
