CTES technology generally refers to the storage of cold energy in a storage medium at a temperature below the nominal temperature of space or the operating temperature of an appliance [5].As one type of thermal energy storage (TES) technology, CTES stores cold at a certain time and release them from the medium at an appropriate point for use [6].
A current is generated under this voltage stress, known as leakage current. Along with this leakage current, the availability of an adequate number of ions (i.e., Na+) on the solar cell surface leads to potential induced degradation (PID). This results in the degradation in the performance of a solar cell. Therefore, leakage current can be used

The grid-connected cabinet is usually equipped with a grounding protection function, and when a leakage or grounding fault is detected, it will automatically cut off the connection between the photovoltaic power station and the grid to ensure electrical safety.
In the 21st century, solar energy is expected to become increasingly attractive as a renewable energy source. An increase in the share of solar energy may destabilize the grid. To overcome the issues of grid instability, specifically in remote areas, BIM and GIS-based microgrid planning based on data can be effectively used. BIM and GIS are
The leakage current of the photovoltaic system has two characteristics: 1. The leakage current is complicated, divided into DC part and AC part; 2. The current secondary value is very small, all in the milliampere level, which requires extremely high accuracy and requires a dedicated current sensor.
When the photovoltaic system regenerates power, it will also generate leakage current, also called common mode current. This is due to the parasitic capacitance between the photovoltaic system and the ground. At this time, a loop is formed between the power grid, the photovoltaic system, and the parasitic capacitance.
The leakage current generated by the photovoltaic system generally includes both the DC part and the AC part. When it is connected to the grid, it is very easy to cause electromagnetic interference and other problems, which not only damages the equipment in the grid, but also may cause electric shock hazards to users or staff.
