Integration of Offshore Wind with O&G Platforms with an Energy Storage System

Abstract

Offshore O&G exploration companies are moving to greater depths to access more abundant O&G reservoirs in deeper waters, resulting in higher costs for HVDC power transmission. As such, an integrated system consisting of an offshore floating wind farm and O&G production platforms with a battery energy storage system (BESS) is proposed in this paper. Transient stability results of the proposed system shows a reduction in transient deviation in load power from-19% to +2/-10%, which meets the IEC and NORSOK standards for O&G platforms. In addition, the load power is also maintained close to 1 p.u. during the transient period.

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

“…In the typical system, the O&G platforms are equipped with 2 x SCGTs (16.4-MW) and standby 1 x SCGTs (8.2-MW), where two SCGTs act as essential generators (EGs) and the other serves as an emergency essential generator (E.EG). The typical OG platforms have a fixed load of around 8.5-MW, as discussed in [11]. The conventional system consists of 1 x 6-MW Siemens (SWT6.0-154) Permanent Magnet Synchronous Generator (PMSG) floating WTGs connected in parallel, which mirrors the Hywind Park configuration in the North Sea [15].…”

“…This is further driven by the fact that capital expenditure (CapEx) of O&G platforms will be higher if subsea transmission cables are required to connect to the onshore power grid [10]. Battery energy storage system (BESS) has also been proposed to integrate with an offshore floating wind farm and O&G production platforms for load flow analysis without considering voltage and frequency deviation [11]. A subsequent study on transient stability analysis with ETAP on O&G platforms with WTG and 2MW of BESS has shown that the voltage and frequency deviations meet the IEC standards 61892-1 for oil and gas industry [12].…”

In that paper, the emergency essential generator has been removed but two 25-MW essential generators (EGs) are in operation with 2-MW of BESS, which results in one of the EG being on standby mode and emitting carbon emissions.…”

Energy Management Strategy Designed for Offshore Oil Rig with Offshore Wind

“…The technology of battery energy storage system (BESS) has been decreasing in cost swiftly over the years due to high demand in improving power stability [9]. This is a critical element in transient stability improvement, which has always been the main research focus in the integration of OOR and WTG that is introduced in [10], [11]. Since then, a similar application has been presented in [12].…”

Design of Stand-Alone O&G Water Injection System Fed by Wind Generation with Battery Support

“…The results showed the load demand control to follow the wind variations contributes to a lower average rotor speed deviation. Reference [7] proposed a system consisting of an offshore floating wind farm connected to an O&G production platform with a BESS. Due to the incorporation of BESS, one of the gas generators was no longer required resulting in reduced greenhouse gas emissions.…”
