Finally, seasonal energy storage planning is taken as an example1 to clarify its role in medium - and long-term power balance, and the results show that although seasonal storage increases the configuration cost of energy storage, it can reduce the operating cost and improve the economy of the system as a whole. The multi-stage low-carbon planning of multi
As summarized in Table 1, some studies have analyzed the economic effect (and environmental effect) of collaborated development of PV and EV, or PV and ES, or ES and EV; but, to the best of our knowledge, only a few researchers have investigated the coupled photovoltaic-energy storage-charging station (PV-ES-CS)''s economic effect, and there is a

In recent years, energy geo-structures have been widely studied such as energy piles, energy tunnels, and energy diaphragm walls , , . They represent geo-structures embedded with thermal loops to serve as heat exchangers. In this way, the energy geo-structures serve two functions simultaneously. One is the primary geotechnical function, and the other is
Recently, the operation of electric charging stations has stopped being solely dependent on the state or centralised energy companies, instead depending on the decentralization of decisions made by the operators of these stations, whose goals are to maximise efficiency in the distribution and supply of energy for electric vehicles. Therefore, the
