Learn About Integrating Wind Turbines for FPSO Optimal BESS Sizing using ETAP, and PSCAD Co-simulation

You must perform load flow, short circuit, motor acceleration, and transient studies. And probably if you want to capture the behavior of the wind turbine generator, and the battery energy storage systems, then ETAP plus PSCAD Co simulation gives you an optimal result. You must perform harmonic analysis, protection coordination, and [transformers behavior].

Renewable integration for existing Floating Production, Storage, and Offloading vessel

Challenges

  • To find a model and a tool to make electrical calculations for power system studies for FPSO with Wind Turbines.
  • To find methods to limit short circuits, minimize outage of gas generator, and ensure protection, while able to start high-power motors.
  • To size and choose Battery Energy Storage System, according to forecasts of wind energy fluctuations. To take into account the load variation handled by the governor.
  • To reduce fuel energy spending. 25% of energy should be made by renewable sources (wind). Carbon emissions should be reduced.
  • Feasibility studies concerned with different scenarios and prediction of events, related to the high incident arc flash energy should be taken.

Which solutions do they choose?

Selected applications

They chose the ETAP modeling software with Load Flow, Short Circuit, Arc Flash. ETAP Digital Twin is the main solution. 

ETAP ensured compliance with all needed electrical standards for designing and calculating the FPSO, BESS, and Renewables electrical installations.

Why do they use Etap?

Main Customer Benefits

  • Digital modeling of the real system with generators, motors, wind turbines, busbars, and locations.
  • Easy management of different scenarios, by adding or deleting symbols representing real equipment.
  • Analysis of critical issues like short circuits, arc flash, and swing equations using only one modeled workspace.
  • Calculations guaranteed by the Electrical Transient Analysis Program - ETAP.

What do they think about ETAP?

Opinions

ETAP software offers a unified platform integrated with PSCAD Co, enabling you to perform all the necessary studies to assess the technical feasibility of whether the system is working or not.

Mr. Selvakumar S, Business Head at Power Projects

I strongly recommend reading this paper: "An Intelligent Load Shedding System Application in a Large Industrial Facility". This came from an ETAP way back in 2008 as an IEEE paper. So, if you go through this paper, the problems we are discussing will be more relevant and easier to understand.

The transition towards sustainable energy sources is driving innovative solutions in the offshore oil and gas industry. The presentation delves into the integration of a Wind Turbine Generator (WTG) into an existing Floating Production Storage and Offloading (FPSO) vessel to reduce carbon emissions. The technical and operational challenges of this integration are discussed, including load balancing, intermittency of wind energy, transformer energization, motor starting, protection coordination, and maintaining operational reliability. The study utilizes simulations with tools like HOMERPRO, ETAP, and PSCAD to assess the technical feasibility of integrating the WTG and Battery Energy Storage System (BESS) into the FPSO power system. Various studies, including load flow, short circuit, motor acceleration, transient stability, voltage ride through, harmonic analysis, protection coordination, and transformer energization are conducted to ensure the effectiveness and efficiency of the proposed system. There is great potential for reducing the operational carbon footprint of FPSOs by incorporating renewable energy sources and using software simulations to address the complexities and considerations involved in such integration.
