A novel reliability-oriented assessment method for coastal urban region spatial resource and power yield analysis for offshore wind farms

Year: 2025

Type: article

Abstract: This study presents a comprehensive methodology for optimizing and evaluating offshore wind farms, focusing on maximizing energy production while minimizing costs. The approach integrates an improved marine spatial resource classification method, which considers both natural and social factors, to determine available sea area. And a 3D wake model is used to accurately calculate the Annual Electricity Production (AEP) and Levelized Cost of Electricity (LCOE) and combined with numerical simulations to determine the most efficient wind farm layout. Validation using 24 years of wind data from Hong Kong demonstrates the methodology's effectiveness. The results reveal a potential construction area of 246.44 km² for offshore wind farms in Hong Kong. Among five turbine models evaluated, the 12 MW model achieves the highest AEP and lowest LCOE. The LCOE is highly sensitive to both the actual energy output of the turbine and the costs associated with turbine and infrastructure installation. With 88 turbines installed, the wind farm could generate approximately 102,191 GWh annually, accounting for 5.515 % of Hong Kong's final energy consumption in 2022. This study highlights the significant potential of offshore wind energy in addressing energy demands and environmental goals.
