Abstract

This study presents proposed pseudo-inspired chaotic bat algorithm (PI-CBA) for solving economic dispatch (ED) problem in the power system. The ED problem is modelled as a complex mathematical function that takes cost coefficients of all the possible fuel options as well as effects of valve-point loading including transmission losses. Problem involves number of equality and inequality constraints such as power balance, prohibited operating zone and ramp rate limits. Combination of CBA along with a pseudo-code-based algorithm is utilised to solve above problem. The feasibility of the proposed methodology is demonstrated for three different tests comprising 6, 10, 15, 40 and 160 thermal units. A qualitative comparison of the obtained result with other standard population-based meta-heuristic techniques manifests proposed technique's superiority.
