Abstract
A system for supplying electric power to a grid and for supporting the grid is provided. The system includes (a) a power generator including a main converter, (b) an energy buffer including an energy storage and a secondary converter, (c) a grid stability monitor-configured to provide a grid stability, and (d) a controller configured to control the main converter and the secondary converter in dependency on the grid stability indication such that when the stability level is at least equal to a predetermined threshold value, the main converter is controlled to operate as a virtual synchronous machine and the secondary converter is controlled to operate to maintain a predetermined amount of energy in the energy storage, and when the stability level is below the predetermined threshold value, the secondary converter is operated to provide a predetermined response in order to support the grid stability.
