Abstract: Synchronization system and method for a power generation unit coupled to an electrical power system, in order to facilitate the synchronization between the power generation unit and the electrical power system. A synchronization signal (SS) is generated by means of at least one Phase-Locked Loop (4) from a main electrical signal (Se) received from the electrical power system. The Phase-Locked Loop (4) comprises a controller scheme with a plurality of gain parameters (Kmn) to eliminate at least some of the deviations of the synchronization signal (Ss) in respect of the main electrical signal (Se), and said gain parameters (Kmn) are adjusted depending on the frequency and the amplitude of said main electrical signal (Se).

Abstract: The invention relates to a virtual controller of electromechanical characteristics for a static power converter that includes a PLC (23) (power loop controller), which receives, at the input thereof, the power difference (?P) between the input power (Pin) (power delivered to the converter by the primary source) and the power delivered to the grid (Pelec) and is able to modify online the parameters of the virtual inertia coefficient and the damping factor as a function of the desired response and of the grid conditions for different frequency ranges.

Abstract: The invention relates to a virtual admittance controller based on static power converters, comprising a control loop into the inlet of which is injected the difference in voltage between a virtual internal voltage (e) and the voltage at the network connection point (v). Said difference in voltages feeds a virtual admittance processor (13) that determines the value of a reference current (i*) that it communicates to a current source (14), said current source physically injecting said current into the network (15).
