The power demand from EVs, correlated with the charging speed of these vehicles, depends on the number and individual power of the charging points as well as the distribution of charging stations among different categories, namely home charging points (typically low power), workplace charging (low to medium power), and public charging stations (medium to high power).
The paper addresses the economic operation optimization problem of photovoltaic charging-swapping-storage integrated stations (PCSSIS) in high-penetration distribution networks. It proposes a dual-layer optimization scheduling model for PCSSIS clusters and distribution network systems. Firstly, a master–slave game model is constructed.
The proposed dual-stage MPC-based voltage control strategy is validated on the 33-bus distribution network and IEEE 123-bus distribution network as shown in Fig. 6 and Fig. 7, respectively. Both the test networks considered are assumed to be three-phase balanced systems.
With the established distribution network topology, placing the electric vehicle charging stations (EVCSs) and distributed generation (DG) units (i.e., infrastructure planning) will affect the system voltage stability (unstable voltage), power quality, and power loss. Therefore, proper planning plays a vital role.
Ultimately, the integration of these photovoltaic devices forms the Photovoltaic Charging-Swapping-Storage Integrated Station (PCSSIS) 7, organically combining charging, swapping, and energy storage functions, providing more sustainable energy support for the future development of electric vehicles.
