Ant Colony Algorithm for the Coordination of Wind and Thermal Generation Dispatch

Abstract

This paper presents the coordination of wind and thermal generation dispatch using Ant Colony Approach. Wind power is unpredictable and intermittent. As wind power penetrations increase in current power systems, its impact to conventional thermal unit should be investigated. The objective of this paper is the development of better wind thermal coordination economic dispatch which is necessary to determine the optimal dispatch scheme that can integrate wind power reliably and efficiently. In this paper Ant Colony Algorithm (ACA) is utilized to coordinate the wind and thermal generation dispatch and to minimize the total production cost in the economic dispatch considering wind power generation and valve effect of thermal units. A ten generator system with one wind power plant is tested to validate the effectiveness of the proposed model and method. Different simulations with and without wind power production are simulated. Simulation result shows the effect of wind power generation in reducing total fuel cost.
