Will the national grid be controlled by frequency converters?

State grid will be controlled by frequency converter. According to the introduction of the World Inverter Network, the inverter is the core device of the state grid speed regulation system, and it has been widely used in the state grid operation system because of its advantages of wide speed regulation range, high precision and good dynamic response. In the national grid transmission system, substations need to convert high-voltage current into low-voltage current suitable for urban and domestic use. In this process, the frequency converter will be used to control the following factors, such as voltage and current.
