Evaluation of the maximum allowed capacity of offshore wind power in Taiwan based on the existing transmission capacity limits

In response to the global renewable energy development, the associate transmission line upgrade is significant. The wind resource in Taiwan is abundant, especially in offshore areas. The target for the installed capacity of the offshore winds in Taiwan is up to 3GW by 2025. However, it is necessary to evaluate the potential transmission congestion owing to the offshore wind power integration and identify the maximum allowed capacity of offshore wind power in Taiwan. There are many constraints for wind power integration. One of the main impacts is congestion of the transmission line due to the limitation of transmission capacity. Therefore, this study implemented system simulations under various scenarios and achieved the maximum allowed capacity of the offshore wind power integration in Taiwan. This analysis was based on the constraints of transmission line limits, and the actual system parameters were utilized. The simulation results provide a significant reference to develop Taiwan's offshore wind energy.
