Awardee Cost Share: $3,240,262. Project Description: In this project, EPRI will work with five utilities to design, develop and demonstrate technology for end-to-end grid integration of energy storage and load management with photovoltaic generation. The technology is a simple, two-level, and optimized control architecture.
One of very promising means to meet the decarbonisation requirements is to operate ships with sustainable electrical energy by integrating local renewables, shore connection systems and battery
North Sea Energy Hubs can be important stepping-stones for large-scale system integration and therefore are one of the central elements in the North Sea Energy program. Energy hubs are defined as offshore energy systems where the production, conversion, and/or storage of energy commodities (electricity, natural gas, hydrogen) and CO₂ are co
The variety of pulsed and intermittent loads aboard a DC ship power system requires a proper choice of energy storage devices and techniques for the optimal design. In this work, a candidate power system is first described that includes generation, energy storage, propulsion loads, a service load, and pulsed loads.
Moreover, a ship''s energy consumption per unit of time is approximately proportional to the third power of the sailing speed [37].Therefore, if a ship burns more expensive fuel inside ECAs, it needs to slow down inside ECAs to
