Abstract: Optimal reactive power dispatch (OPRD) is a very immense issue in power system, which is a complicated non-linear optimisation issue. Therefore, a good metaheuristic algorithm called kinetic gas molecule optimisation (KGMO) is proposed for solving multi-objective OPRD (MOPRD) problem which is enhanced by calculating acceleration coefficients and inertia weight dynamically rather than a constant value. Also, three flexible AC transmission system (FACTS) devices like static VAR compensator (SVC), thyristor-controlled series compensator (TCSC) and unified power flow controller (UPFC) are optimally allocated in the test system. Since the cost is increases considerably with these devices, so, power generation pricing also calculated in this work. This research is implemented in IEEE 30 bus system, and it is validated from MATLAB, which shows the value of power loss as 4.3583 and voltage deviation as 0.26499 with cost of 469.6417 $/MVAR, which is compared with implemented particle swarm optimisation (PSO) results.
