PV energy storage charging stations are usually equipped with energy management systems and intelligent control algorithms. The aim is for them to be used for detecting and predicting energy production and consumption and for scheduling charging and allocating energy based on the optimization results of the algorithms.
Charging stations are designed to achieve optimal energy utilization and meet user needs and grid requirements. Electricity generated by PV power generation can be used for a variety of purposes, such as charging EVs, grid support, and battery storage.
When establishing a charging station with integrated PV and energy storage in order to meet the charging demand of EVs while avoiding unreasonable investment and maximizing the economic benefits of the charging station, this requires full consideration of the capacity configuration of the PV, ESS, and charging stations.
Challenges: Capacity Allocation and Control Strategies The integrated PV and energy storage charging station realizes the close coordination of the PV power generation system, ESS, and charging station. It has significant advantages in alleviating the uncertainty of renewable energy generation and improving grid stability.
One of the major challenges for EV charging stations, especially the public ones, is to decrease charging time. This can be addressed by increasing the rate of power transfer. The fast charge method, according to European Standards, corresponds to the maximum value of power (50–100 kW).
Grid Stability Integrated PV and energy storage charging stations have an impact on the stability of the power grid. Suitable design and control strategies are needed to minimize the potential impacts and improve the stability of the grid.
