Recently, the idea of an "energy sphere" has been introduced as a proficient strategy for optimizing multiple energy systems simultaneously [17, 18]. Energy spheres consist of different energy sources and demands, including electricity, heat, and cooling, and are interconnected through multiple energy conversion mechanisms [15, 19].
Ice storage systems basically consist of chillers and ice storage mechanisms. Chillers function to produce ice under ice-making conditions, where ice is formed in tanks during low-demand periods and then used to meet cooling needs during high-demand periods [17, 30].
As a result, operators can reduce operating costs by changing consumption patterns and taking advantage of the adaptability of thermal, electric, and cooling needs, as well as the versatility of integrating different forms of energy. In addition, energy spheres can reduce their operating costs by selling excess energy back to upstream networks. 3.
It shows that during the periods of peak electricity demand from 10 a.m. to 10 p.m., which coincide with high gas prices, the operator of the energy sphere satisfies its electricity demand by purchasing electric energy from the upstream network.
Energy storage systems are strategically charged and discharged as part of the energy domain design to minimize total daily operating costs. In most cases, the energy domain operator chooses to generate energy with in-house facilities rather than purchase expensive energy from external grids.
In addition, electric chillers (ECs) are used to meet excess cooling demand. Energy storage systems are strategically charged and discharged as part of the energy domain design to minimize total daily operating costs.
