In , based on Matlab, a simulation model of photovoltaic power generation integrated into the distribution network is built, and the impact of a single photovoltaic power generation system and multiple photovoltaic power generation systems on the power quality, harmonics, and DC components of the distribution network is analyzed.
When the rated capacity of the connected distributed photovoltaic is equal, the short-circuit capacity ratio is small, and the short-circuit capacity of the grid-connected point is large, indicating that the electrical distance between the node and the system power supply is small and the connection is close.
For low-voltage solar power stations that are connected to the grid, the PV grid connected cabinet can also incorporate additional devices for functions like measurement and protection. GGD AC low-voltage distribution cabinets are suitable for power plants, substations, and industrial enterprises.
The photovoltaic power station connected to the grid should be able to control the grid-connected point voltage within the range of 97% ~ 107% of the nominal voltage when the grid voltage is within the normal range.
At the same time, the integration of distributed solar power plants into the power grid has a great impact on the current flow direction and voltage quality of the original power system and brings great challenges to the safe and stable operation of the power grid.
