Reliability/Cost Implications of Utilizing Wind Energy in Small Isolated Power Systems

Abstract

The rapid growth of wind energy applications in electric power systems dictates a need to develop comprehensive techniques that can be used to evaluate the economics involved and the reliability of power supply that can be achieved from the utilization of wind energy sources. These sources have the potential to significantly reduce operating costs in small isolated systems which are generally supplied using costly diesel fuel. This paper presents a simulation method that provides objective indicators to help system planners decide on appropriate installation sites, operating policies, selection of wind or diesel units in capacity expansion and optimum wind energy penetration levels when utilizing wind energy in small isolated power systems.
