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.

Dynamic load demand affects output power to load, which may fail to meet IEC standards 61892-1 for offshore oil and gas installation. High power consumption in offshore oil rig requires both large gas and wind turbine generation that are unable to react quickly to enhance transient stability. Hence, an energy management system (EMS) is designed with a battery energy storage system (BESS) to replace partial output power from the gas turbine onboard the oil rig for optimal transient response. Our designed EMS differs from the current state of art by not using a low-pass filter so as to improve rapid response from BESS , while enhancing output power quality to load. Our EMS is validated with maximum transient voltage and frequency deviations in simulation to illustrate improved transient stability results.

The CapEx of offshore floating wind turbine generation (WTG) and battery energy storage system (BESS) have declined over the years which increases the cost feasibility of replacing gas turbine power generation in offshore oil and gas (O&G) platforms. This paper presents a study of an integrated system consisting of an offshore floating wind turbine generation (WTG) and O&G production platforms with battery energy storage system (BESS) onboard to meet the load demand. It is shown in cost analysis that the integrated system consisting of BESS can lower overall cost in CapEx and OpEx, as compared with a typical system fueled by gas turbine generation. Moreover, transient stability in simulation has shown that the proposed system 2 has a significant reduction in both voltage and frequency transient deviations, with transient recovery time that could meet the IEC standards 61892-1 for O&G platforms.

The electrification of offshore O&G platforms with offshore wind farms in the off-grid configuration 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 on-board battery energy storage system (BESS) is proposed in this paper. With this proposed system, four different test scenarios are simulated in ETAP with varying capacity in a modular Battery Energy Storage System (BESS). Results have shown that the transient stability characteristics in a conventional system and a proposed system 1 with only 1MW of BESS, do not meet the IEC standards for O&G platforms. By doubling the capacity of the BESS, ETAP simulation results have shown that a proposed system 2, has a reduction in transient deviation that meets the IEC standard, IEC 61892-1. In addition, the capital expenditure (CapEx) and operational expenditure (OpEx) of proposed system 2 is presented in this paper.

In the marine industry, fuel cell (FC) is being exploited as the primary power source with battery energy storage system (BESS) as complementary resource to be introduced for peak shaving and smoothing control in load fluctuation. As such, an integrated system of Proton Exchange Membrane Fuel Cells (PEMFC) with BESS is being developed to proposed to meet the dynamic three-phase load demand in a micro-grid configuration. In this paper, the transient stability verified by MATLAB/Simulink has shown that BESS is more adaptable than FC to meet constant and dynamic load demand. Moreover, there is an unstable power generation from PEMFC when a non-linear load is introduced. As such, in micro-grid's paradigm that consists of BESS that has the same energy capacity as FC, output power quality during transient period to electrified dynamic load is significantly enhanced. In addition, a proposed control algorithm is presented in this paper. Simulation studies have shown that the integration of PEMFC with BESS in micro-grid configuration offered better transient behaviour with lesser surge of 2%, as compared to BESS with transient surge of 225%.
