Abstract :
To effectively accept the grid-connected distributed solar photovoltaic (PV) output, PV utilization ratio is researched based on the system minimum load at various PV penetrations. The impacts of PV on the electric power system and the main constraints for PV connected to the grid are analyzed. The methods to calculate PV utilization ratio, PV generation cost and annual utilization hours are proposed. The acceptable capacity and utilization of PV can be evaluated by these parameters. Finally, constructive suggestions for optimizing the scheme of PV installation and improving the acceptable capacity of PV are provided.
