The invention discloses a station level virtual synchronous machine control system and method and an application thereof. The station level virtual synchronous machine control system comprises power generation sources with power electronic converters as interfaces and a station level energy management system. The power generation sources access to an upper level power grid through an only common coupling point PPC; the power generation sources use the power electronic converters to realize energy conversion and access to a local grid connected point; the station level energy management system realizes power scheduling of power generation units through detecting PCC points and voltage and frequency of grid-connected interfaces of the power generation source according to a control strategy of the virtual synchronous machine. The station level virtual synchronous machine control system and method and an application thereof overcome flaws in the power electronic converter and the virtual synchronous machine, improves characteristics of primary frequency modulation and voltage regulation of the system through an inertia link of the virtual synchronous motor and can greatly improve stability of the power grid, and is applicable to distribution of high permeation and multiple access points and a big scale concentrated renewable energy power generation system.
