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

Abstract

The promising area of offshore wind power has encouraged wind generation to supply Oil & Gas (O&G) facilities. A potential arrangement comprises a Water Injection System (WIS), as a method for oil recovery in reservoirs, connected to a wind turbine and a Battery Energy Storage System (BESS). However, the wind intermittency poses a challenge for an isolated wind-powered system operation. Therefore, this paper considers a design of a stand-alone system comprised of: a WIS, wind turbine, and BESS based on DC-link interconnection; and proposes a methodology to operate this system aiming to reduce the number of WIS stops. The methodology is based on two perspectives: an energetic analysis in which an energy analytical tool is developed to size the BESS; and a dynamic evaluation performed considering a DC-link voltage-based control to assist the load operation by reducing the WIS stops. The results have shown an adequate performance of the WIS even during moments of lower-wind power generation to the proposed methodology.

“…These conventional power sources have provided reliable energy to OG platforms for decades. However, there is now more interest in incorporating renewable energy sources into OG platforms due to growing worries about climate change, the depletion of fossil fuel reserves, cost reductions, and fuel diversification [152,153]. The challenges, opportunities, and technologies associated with incorporating renewable energy sources, energy storage technologies, and floating WTs into OG platform power systems will be covered in the sections that follow.…”

“…The main problem with wind energy is that it is unpredictable and variable, which might compromise the stability and dependability of the power system. Nevertheless, advances in floating wind turbine technology and the potential for hybrid power systems with energy storage can assist in overcoming these difficulties [78,132,152,153,156].…”

“…Floating WTs are a novel and potential renewable energy solution for OG installations, particularly in deep-sea conditions where traditional fixed-bottom WTs are impractical [152,153,170,171]. This section explores into the technologies and designs of floating WTs, as well as their operations and maintenance.…”

“…❏ Operations: The operation of floating WTs requires frequent control and observation of the system in order to guarantee successful operation and minimal downtime [153,162]. This comprises controlling the wind turbine generator, pitch and yaw systems, mooring lines, and other components.…”

“…❏ Control: The control of a hybrid power system entails the coordinated management of the various energy sources and storage devices to ensure reliable and effective operation [153,180,182]. This consists of real-time control strategies for power dispatch, load management, and storage system usage, as well as predictive control based on predicting renewable energy generation and platform load.…”
