A Novel Hybrid Approach for Optimal Reactive Power Dispatch under Unbalanced Conditions

Recently, the Optimal Reactive Power Dispatch (ORPD) is gaining a considerable attention in the power systems, as they decide the security as well as economy of a power system. The major target behind this works is to upgrade the power system efficiency by means of optimally allocating the real power, so that the power loss should be minimized, and voltage profiles should be enhanced. With this intention, here and optimization algorithm referred as "Trial based Update on Whale and Particle swarm Algorithm (TU-WPA)" is implied, which an amalgamation of two algorithms is called, "Particle Swarm Optimization (PSO) and Whale Optimization Algorithm (WOA)". The TU-WPA model fine tunes the key parameters like "load reactance; voltage and transformer tap settings". Finally, the performance of the TU-WPA is compared over the existing works under "IEEE 14 and the IEEE 39 bus systems". On observing the best performance of the adopted scheme, a higher value (0.35327) is recorded, while the compared models attains comparatively lower values, i.e. GA= 0.26496, FF= 0.27496, PSO= 0.256, ABC= 0.3296, WOA= 0.20333, DA= 0.29432 and CS= 0.30496.
