A multi microgrid integrated energy system framework considering hybrid energy storage operator (HESO) is proposed. It can improve the energy utilization efficiency of the system, reduce the construction cost of energy storage equipment and protect the information security of users.
In an integrated energy microgrid, electric energy storage and thermal energy storage are introduced as short time scale energy storage, and hydrogen storage is introduced as long time scale energy storage. Secondly, the characteristics of renewable energy output and load in different seasons are analyzed.
Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .
This paper provides a critical review of the existing energy storage technologies, focusing mainly on mature technologies. Their feasibility for microgrids is investigated in terms of cost, technical benefits, cycle life, ease of deployment, energy and power density, cycle life, and operational constraints.
As discussed in the earlier sections, some features are preferred when deploying energy storage systems in microgrids. These include energy density, power density, lifespan, safety, commercial availability, and financial/ technical feasibility. Lead-acid batteries have lower energy and power densities than other electrochemical devices.
Microgrids 12, 13 are small, localized energy systems that can generate, store and distribute energy independently or in conjunction with the main energy grid. In this context, community power storage systems are gaining relevance 14 and can serve as nuclei for microgrids in urban areas, offering potential interconnection possibilities 13, 15, 16.
