Moreover, a coupled PV-energy storage-charging station (PV-ES-CS) is a key development target for energy in the future that can effectively combine the advantages of photovoltaic, energy storage and electric vehicle charging piles, and make full use of them .
Detailed data are listed in Table A1, Appendix. A single PV-ES-CS can provide 1000 kWh and the maximum output power is 800 kW. VSC-1 and VSC-3 adopt constant DC voltage control to ensure stable operation of DC lines, while the remaining VSCs adopt PQ control to flexibly control the direction and size of line power transmission.
There are 112 AC and DC nodes in the topology, including 13 critical load nodes, which are represented by “critical load (CL)-” in the figure. Detailed data are listed in Table A1, Appendix. A single PV-ES-CS can provide 1000 kWh and the maximum output power is 800 kW.
This configuration mode can reduce the outage loss to 1,155,800 CNY for a hybrid AC/DC distribution network. The economics are −120,000,000 CNY, which means the total cost of configuring these four PV-ES-CS is 1,200,000 CNY. Solving steps of PV-ES-CS configuration model in AC/DC hybrid distribution network.
