If required by the transmission system operator, the solar plant voltages. a. If the frequency is <50 Hz, the solar plant shall continue injecting active power until the frequency reduces below 47.5 Hz. b. For over-frequency between 50 and 50.2 Hz, the solar power plant shall maintain the 100% of active power. Table 2. Range of voltage at the PCC.
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.
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.
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.
In addition, in, to prevent overvoltage problems in power distribution networks, the use of the battery has an important role and three various scenarios for grid conditions, are tested as the voltage control mode, mitigating reverse power flow mode, and scheduling mode.
The solar power plants shall comply with the requirements specified in Section 5.3 of the Performance Code of the Grid Code and/or the related part in the Electricity Distribution Code.
