Charging pile energy storage system can improve the relationship between power supply and demand. Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
Germany is under increasing pressure to rapidly decarbonize its electricity system, while ensuring a secure and affordable electricity supply. In this context, energy storage systems (ESSs) can play a crucial role in enabling a high share of variable renewable electricity generation.
The charging pile energy storage system can be divided into four parts: the distribution network device, the charging system, the battery charging station and the real-time monitoring system [ 3 ].
Electric vehicle charging piles are different from traditional gas stations and are generally installed in public places. The wide deployment of charging pile energy storage systems is of great significance to the development of smart grids. Through the demand side management, the effect of stabilizing grid fluctuations can be achieved.
The study by Keles and Yilmaz , for instance, considers only the option of pumped hydro storage (PHS), as it is already a key component of the German electricity system. Others consider multiple technology options, with Bartholdsen et al. , for instance, considering also lithium-ion batteries and hydrogen storage (via power-to-gas).
Due to its central location in Europe, Germany is highly interconnected to its neighbors, importing and exporting electricity from eleven other countries. The German electricity system is undergoing a profound change from a formerly coal and nuclear power dominated country to one depending solely on renewable energies.
