The pressure of climate change has been driving the transition of power distribution networks (PDNs) to low-carbon energy systems. Hydrogen-based microgrids (HMGs), as emerging urban energy subsystems in PDNs with significant carbon emissions reduction potentials, are valuable assets in smoothing the economic transition to low-carbon
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential

A short term thermal energy storage with a capacity of 45 MWh is used to decouple the heat production plants from the distribution network. The annual energy stored in the storage tanks from geothermal and waste-to-energy plants is 7000 MWh, which represents almost 4% of the network annual energy consumption.
In bids for a project by Xcel Energy in Colorado, the median price for energy storage and wind was $21/MWh and for storage and solar $36/MWh [6]. This is comparable to $18.10/MWh and $29.50/MWh, respectively, for wind and solar without storage but is still far from the $4.80/MWh median price for natural gas [ 6 ].

Furthermore, an outlook of the power system transition in China is provided by virtue of source-network-demand-storage
However, the optimal planning of charging stations is a non-trivial task, as it requires coordination between planning activities in the transportation and the power distribution network. Historically, the modeling of these two networks has been approached from different research areas and with the use of different methodologies.
Implementing large-scale commercial development of energy storage in China will require significant effort from power grid enterprises to promote grid
Introduction. In a perfectly balanced energy system, the electricity demand and supply have to be perfectly aligned. Energy storage can stabilise the fluctuations in demand and supply by allowing the storage of excess electricity. With the energy system relying more and more on RES, the energy storage has a key role to play in the transition
