Transient Stability Analysis of Offshore Wind With O&G Platforms and an Energy Storage System

The integration of offshore floating wind turbine generation (WTG) with offshore O&G platforms in the off-grid configuration which is a business model that is in the process of developing in the North Sea. As such, an integrated system consisting of an offshore floating WTG and O&G production platforms with onboard battery energy storage system (BESS) is proposed in this paper. In simulation, there are 4 different scenarios and results show that conventional system has high transient stability which do not meet the IEC standards for O&G platforms. The simulation has shown proposed system 2 which has incorporated with BESS 1 and BESS 2, has a reduction in transient deviation that can meets the IEC standards. In addition, capital expenditure (CapEx) and operational expenditure (OpEx) of proposed system 2 is presented in this paper.
