Abstract

Minimization of voltage deviations and power loss can be controlled by Optimal Reactive power Dispatch (ORPD) for voltage stability of the system. This paper presents a real ant colonies foraging behavior procedure for solving the ORPD problem using Ant Colony Optimization (ACO) algorithm. The objective of this paper is to minimize the voltage deviations at load buses using control and dependent variable constraints with proposed sensitivity parameters of reactive power. The On-Load Tap Changing Transformers (OLTC), Generator Exciters, Switchable VAR sources are used as control variables for improvement of system parameters like Voltage deviations, L-index and Power loss. The effectiveness of the proposed method is demonstrated on New England 39-bus system for near optimal solutions. The performance of the proposed method is compared with conventional optimization technique and presented for illustration purpose.
