Power System Stability of Offshore Wind with an Energy Storage to Electrify O&G Platform

The Capital Expenditure (CapEx) of offshore floating wind turbine generation (WTG) and battery energy storage system (BESS) are declining over the years. This can mitigate gas turbine power generation in offshore oil and gas (O&G) platforms with lower cost impact. This paper proposes integrated systems consisting a WTG and O&G production platforms with BESS onboard to meet the load demand. Cost analysis shows that this integrated system paradigm with BESS can lower overall cost in CapEx and Operational Expenditure (OpEx) compared with typical system. Moreover, transient stability in simulation shows that the system 2 has a significant reduction in term of both voltage and frequency transient deviation, with transient recovery time that could meet the IEC standards 61892-1 for O&G platforms.
