According to the analysis of Power Transmission Company 3, the mass energization of wind power plants will cause to many problems in the operation of the power system such as: full load, long-term overload, low voltage, etc. In addition, the operation management unit also has difficulty in arranging many personnel to coordinate the technical design agreement, construction plan agreement, acceptance testing, energizing connection points, especially the task to ensure the safe operation of the power grid during the power outage for construction and testing of connection points.
