Cost of energy reduction for offshore wind energy in South-central Coast, Viet Nam

Abstract

This article aims at reducing the cost of energy by targeting the optimal power of the wind generator of offshore wind farms in a region in Vietnam. The research employs various scaling laws for mass and cost calculations. The calculations are implemented using wind data of a specific region on the South-Central Coast. The permanent magnet synchronous generator with high efficiency, light-weight, and compact design will be used for the wind generator. The levelized cost of energy as a function of the generator’s nominal power is then built to figure out the optimal power of the wind generator. Results show that future offshore wind farms with monopile foundations having a mean wind speed of about 6.5 m/s should be installed with a turbine's nominal power of 7 MW.
