A HYBRID WIND-WAVE ENERGY SYSTEM WITH BATTERIES FOR OFFSHORE OIL AND GAS PLATFORMS
Ahmad Mohammad Saber Abdelsamie;
Abstract
Summary:
The offshore Oil and Gas (OOnG) sector accounts for a great portion of Greenhouse gases (GHG) emissions. The idea of the electrification of OOnG platforms by clean sustainable energy sources, namely wind and wave, was a turnaround. Combining wind energy turbines (WETs) and wave energy converters (WECs) for less generation variability has been recently proposed in literature. OOnG electric loads are of high sensitivity, and though require a high level of reliability, which contradicts with the intermittent nature of winds and waves. The usage of battery packs could help decrease these variations. But practical batteries are known to degrade over many factors. In this thesis, a comprehensive study is presented on quantifying the change in reliability of electric supply caused by coupling of a wind-wave (WW) hybrid offshore energy converter unit (HOEC) with Lithium-based energy storage (LBESS), while considering LBESS’s degradation. A case study on USA’s largest oil port was carried out to demonstrate this hypothesis. A variety of WW ratios were studied. For each ratio, the maximum possible load level and the optimal battery size were calculated. The optimisation problem was solved using a simple-yet-robust systematic approach.
