This paper presents a recently invented recurring multi-objective differential evolution (RMODE) to minimize real power losses of total transmission lines and for voltage stability improvement. This multi-objective reactive dispatch (MORPD) problem has been devised as a constrained nonlinear optimization problem with the objectives of total transmission lines real power losses minimization and voltage stability improvement by minimizing stability index in a power system. In the proposed recurring MODE algorithm, MODE is employed again and again with the efficient solutions in hand and initializing the leftover inhabitants only in each round of RMODE algorithm. Usefulness of the RMODE algorithm is established by solving MORPD problem in the two cases, one standard 30-bus IEEE test system and other Indian practical 75-bus system, and by comparing MORPD results with those obtained using NSGA-II, multi-objective PSO, MODE, hybrid multiple-swarm PSO algorithm and with the reported results. On comparison, RMODE algorithm is found to be a potential approach for handling multi-objective ORPD problem in power systems.
