A novel brainstorm based optimization method for optimum planning of reactive power with FACTS devices

This paper presents a solution for planning of reactive power using a novel brainstorm optimization method with flexible alternating current transmission system (FACTS) devices. For shunt compensation static VAR compensator (SVC) and for series compensation thyristor-controlled series compensator (TCSC) are being used in this proposed work which is adapted into IEEE-14, IEEE-30 and IEEE-57 test bus system. The location for TCSC and SVC has been chosen by performing power flow analysis. In this paper brainstorm optimization algorithm (BSOA) is proposed to evaluate the optimal value of reactive VAR generation of generators, tap setting of transformers, and size of SVC and TCSC to reduce the active power loss as well as operating cost in the transmission network. The outcomes proposed by BSOA approach is obtained and compared with some other techniques like krill heard algorithm (KHA), symbiotic organisms search (SOS), particle swarm optimization (PSO), biogeography-based optimization (BBO) methods.
