The connection of a photovoltaic plant to the electrical grid can be at low voltage (230/400V), medium voltage (usually 15kV or 20kV), or high voltage (132kV). The type of connection between the three just illustrated depends on the power of the system.
The SEGCC specifies the special requirements for connecting both Medium-Scale Solar Plants (MSSPs) and Large-Scale Solar Plants (LSSPs) to the distribution networks or to the transmission network according to the capacity of the solar power plant. The capacity of MSSPs’ range is from 500 kW to less than 20 MW.
Depending on its capacity, a solar plant can be connected to LV, MV, or HV networks. Successful connection of a medium-scale solar plant should satisfy requirements of both the Solar Energy Grid Connection Code (SEGCC) and the appropriate code: the Electricity Distribution Code (EDC) or the Grid Code (GC) as the connection level apply.
Current power systems are not designed to support the massive integration of PV and to respond to the grid codes. The application of intelligent and online control methods for better coordination between all parts of modern electrical systems is very important.

How Does a Solar Farm Connect to the Grid?
Power generating plants such as solar farms output power at different voltages, too. If the nearest transmission line to your property has a voltage of, say, 115 kV (115,000 volts), the output voltage from the solar farm needs to "step up" to 115 kV to feed power into it. Likewise, the power that line carries to a neighborhood 50 miles away ...
