Simulating Converter System with Energy Storage for Offshore Applications

Abstract

This thesis focuses on simulating a power converter with an energy storage system for peak loads shaving in offshore oil and gas processes and operations. Oil and gas industry operations often encounter peak power demands that strain the existing power system, leading to inefficiencies in power and increasing costs. To mitigate these concerns this peak shaving system is proposed and simulated a model to observe how system reacts.

The simulation framework is a collection of subsystems of ESS, power converter system, grid, an induction motor and an auxiliary load. By modelling these systems together and without the peak shaving system, the behavior of the power system due to peak loads can be replicated and analyzed. Integration of offshore renewables and regenerative energy in offshore platforms are discussed to facilitate charging options for the onboard energy storage.

The simulation model elaborates the economic benefits considering factors of fuel consumption and capital cost and through the comprehensive studies, this thesis contributes to development of sustainable energy solutions in offshore oil and gas field.
