As expected, increasing the size of the TES tank in all cities drove to a higher use of this system. Regarding to Helsinki, its high annual heating energy demand (Table 11) did not allow to overcome a 60% of the TES tank use. Higher volumes should be studied to increase the incidence of the storage to the global heating energy supplying.
In [13], the energy storage systems (ESS) integrated with renewable energy sources (RES) were installed in a medium-voltage primary electrical distribution system and controlled based on a stochastic, adaptive, and dynamic approach to minimize the daily operation cost of system managed by the local distribution company (DISCO).

Energy storage is an essential part of energy management systems that provides a balance between supply and demand for energy over a time period [5]. Cold storage systems have been used in different applications including refrigeration systems, air conditioning, and conservation and transport of temperature sensitive materials [6].
1. Introduction. With the rapid development of society and industry, the world today is facing various energy challenges and threats [1], [2].Overexploitation of fossil fuels, global climate change, and environmental pollution are particularly prominent among them [3].To address these issues, it is imperative to actively advance technologies for
Generally, power demand energy storage will have these two features but energy demand energy storage has the energy density only.

Integration of demand response (DR) programs and battery energy storage system (BESS) in microgrids are beneficial for both microgrid owners and consumers. The intensity of DR programs and BESS size can alter the operation of microgrids. Meanwhile, the optimal size for BESS units is linked with the uncertainties associated with renewable energy
The working principle of a controllable on-demand heating system based on off-peak electricity energy storage (COHSBOEES) is as follows: the cheap off-peak electricity energy is converted into heat energy for storage in the evening, and the heat energy can be extracted on demand for heating during daytime peak or flat electricity
