Synergistic Enhancement of Power System Security using Real Coded BBO based Security Constrained Optimal Generation Dispatch

Abstract

A Real Coded Biogeography (RCBBO) integrated Security Constrained Optimal Generation Dispatch (SCOGD) is proposed in this paper as a method to relieve transmission line overloading. Overloading can be related with system security which is the capacity system of the system to stay at ease at some point of atypical conditions. Assessment of system security deals with assessing the secure and insecure operative states, whereas the security improvement offers with the mandatory control motion towards overloads beneath a contingency situation. Through generation rescheduling [1] the overloaded strains are mitigated from the severity. With the planned RCBBO algorithm, to improve the safety vectors, dynamically variable parameters specially the immigration and emigration rateare included as opposed to the mounted values of the parameters. The SCOGD procedure includes programming of generators to minimize the severity index with minimum fuel price. An IEEE-30 bus system is taken into account to check the effectiveness of the proposed approach. Numerical outcomes screen that, for ten iterations the deliberate BBO algorithm out performs the opposite revolutionary algorithms such as cuckoo search (CS), Bat algorithm (BA) and particle swarm optimization (PSO) in getting the minimum fuel charge and therefore the minimal severity index in minimum time. Consequently, the planned BBO set of rules is found to be rapid converging and within economic constraints to arrive at a viable solution for SCOGD problem.
