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.
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.
By using BSS to manage the charging of EVs, microgrids can mitigate grid congestion issues caused by multiple EVs charging simultaneously. BSS can distribute the charging load intelligently, considering grid constraints and available capacity, to prevent overloading and ensure a reliable power supply to both EVs and other critical loads .
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.
This approach solves the energy supply problem of the charging station, improves the utilization of the PV system, and achieves an energy contribution to the grid while meeting the charging needs of EVs. Yao et al. designed a system that utilizes PV power generation and an ESS to provide charging and discharging for EVs.
