Abstract—In this paper a new hybrid optimization algorithm, referred to as Crossbreed spiral dynamics bacterial chemotaxis algorithm (CSDBCA) is proposed to solve the optimal reactive power dispatch (ORPD) Problem. CSDBCA synergizes bacterial foraging algorithm (BFA) chemotaxis approach and spiral dynamics algorithm (SDA). The original BFA has higher convergence speed while SDA has better accuracy and stable convergence when approaching the optimum value. This crossbreed approach conserves the strengths of BFA and SDA. So the CSDBCA has the capability of producing superior results. In order to evaluate the proposed algorithm, it has been tested on IEEE 30 bus system consisting 6 generators and compared other algorithms and simulation results show that CSDBCA is more efficient than others in solving the reactive power dispatch problem.
