Abstract
In this paper, an overview and the state of art of energy storage technologies in the deep-sea are presented. This research aims to develop simulating model of a deep sea hydro energy storage system (DSPHESS). The tools used to develop this system was HOMER which can simulate, optimize and does the sensitivity analysis of the model. To establish the HVDC connectivity for the main grid SIMSCAPE libraries which has a properties of Simulink and control system engineering was used. The entire system operates in contrast to Pumped Hydro-Electricity Storage on land. Using a depth provided by the deep sea just beyond the continental shelf, an undersea stainless steel sphere is created, with a turbine pump/alternator plant. This is connected to the ocean surface, where a snorkel (static head) is supported by a floating platform. During times of excess renewable energy on the mainland AEMO system, the water would be pumped out of the hemisphere storage and introduced to its void space by the snorkel surface connection. The system deals for generation of power in the deep sea and depth is up to 4000-5000m. When there is a need for peak power or during load fault response on the AEMO grid, significant quantities of renewable energy resources can be extracted, by allowing the deep sea water(driven by its hydrostatic head) through the turbine alternator, generating electricity for a return to the mainland grid. Considering the economics and technology availability, deep sea pumped hydro storage technology has a role to play where there are narrow continental shelves, such as in NOWRA (NSW), for specified Australian location operating within Australian energy markets.
