CAPTURE OF MAXIMUM WIND ENERGY FOR CONSTANT FREQUENCY OFF SHORE WIND FARM USING NOVEL CAPRA OPTIMIZATION ALGORITHM

Abstract

This paper proposes that in wind power system design a powerful optimization technique can successfully maximize energy capture at given site, thus proposes a Novel Capra Optimization Algorithm (NCOA). Maximizing wind energy capture NCOA employ most common Constant frequency (CF) scheme as an alternative of using Variable frequency (VF) scheme. Since VF has the main drawback in controlling independently the speed of each turbine. Hence this paper proposes NCOA make an effort to enhance CF scheme for capturing maximum wind energy. NCOA is to evaluate for different wind speed scenarios applied to a standard case studies of constant electrical frequency off shore wind farm. The case study considers a wind farm composed of single turbine and four wind turbines based on synchronous generator. The simulation shows a significant enhancement of CF scheme 20% more than the VF scheme using NCOA and 94% percent of capture of total available wind power.
