Distributed optimal power flow using bacterial swarming algorithm. (14th May 2010) - Wu, Q.H.
With the increasing use of distributed intelligent devices and the demand of separated power network managing, distributed control of a complex power system becomes more and more important in application. In a distributed power flow optimisation, the cost of the network can be optimised by coordinating the control of generators and taps in a subarea partition. In this paper, a bacterial swarming algorithm (BSA) is presented to solve an optimisation problem of distributed power flow. BSA is designed from a searching framework that combines the underlying mechanisms of bacterial chemotaxis and quorum sensing. The algorithm has been evaluated by simulation studies, which were undertaken on an IEEE 118-bus test system, in comparison with a genetic algorithm (GA) and a particle swarm optimiser (PSO).
