Abstract
The increasing penetration of renewable resources causes some challenges like the electric power demand prediction uncertainty and energy surplus. Energy storage systems (ESS) are promising solutions for these challenges. However, considering the marginal capacity of ESSs according to the installation area and the economic portion of ESSs according to the installation capacity, the use of battery ESSs to reduce surplus energy is not efficient and has practical limitations. To efficiently resolve the challenges, a multi-energy system (MES) that is capable of operating different energy sources, such as natural gas storage (NGS), thermal energy storage (TES), ice energy storage (IES), and hydrogen energy storage (HES) has been proposed. The centerpiece of converting and managing multiple energy sources associated with the MES is the energy hub (EH). In this paper, we reviewed and compared the performance of existing ESSs and the MES, and the results have demonstrated the superiority of the MES. In addition, EHs that include power-to-gas, combined heat power, and combined cooling heat power, have been examined based on their structural characteristics. A review of the methods and the primary purpose of MES is also highlighted in this paper.
Highlights
Due to the rapid increase in energy generation from renewable sources, flexibly using multiple energy sources as an efficient avenue for surplus power utilization attracts significant attention
In this study, we have examined several single energy systems that are commonly used for constructing an multi-energy system (MES)
The economics and reliability associated with the MES were analyzed by mathematical modeling based on a coupling matrix
Summary
Due to the rapid increase in energy generation from renewable sources, flexibly using multiple energy sources as an efficient avenue for surplus power utilization attracts significant attention. The structure and objectives of the MES are examined This investigation is divided into the following three parts: In Section 2, the operational principles of existing single systems of different energy types are briefly described and previous studies are highlighted. This means that the P2G system is not restricted to supplying hydrogen to the load, but is flexible in the system operation compared to existing systems. E. MULTI-ENERGY ANALYSIS the supply of heat and cooling energy through CHP and CCHP is determined according to each energy demand, hydrogen energy using P2G technology is often used to increase energy utilization depending on the degree of renewable energy use without being affected by hydrogen load.
