Wind-storage-turbine Bundled Technology for the Power Supply of Offshore Oil and Gas Platforms

Abstract

Abstract The offshore oil and gas industry is embracing renewable energy such as wind power to reduce carbon emissions. However, the intermittent characteristics of renewable power generation bring new challenges to the operation of existing offshore oil and gas platforms featured in minor load variation. To address the concern, this paper proposes a coordinative control strategy for offshore oil and gas platforms with floating wind power integrated. A saturated filter controller is applied to decompose the wind power fluctuation and smooth it with energy storage and a gas/oil turbine generator. A feedforward control unit is embedded into the controller to compensate for the wind power variation caused by the floating foundation. The proposed strategy is validated using a model extracted from a real offshore oil and gas platform. The result shows that the proposed strategy can validly eliminate the impact of wind power volatility.
