Photovoltaic grid-connected cabinet is a distribution equipment connecting photovoltaic power station and power grid, and is the total outgoing of photovoltaic power station in the photovoltaic power generation system, and its main role is to act as the dividing point between the photovoltaic power generation system and the power grid.

Thermal energy storage is an essential and inevitable component in solar vapor absorption systems to level the mismatches between the demand and supply of the heat. Additionally, TES aids to improve the performance by smoothening the output and thus, increasing thermal reliability of the system.
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.
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.
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.

Along with the specific characteristic of the solar modules (inability to shut off the voltage other than by obscuring the solar panels and generation, by the strings, of short-circuit currents with values very near to those produced in normal conditions), the presence of voltage as high as 300-600 V d.c. and beyond requires a very careful ...
