SUITABILITY OF SOLAR PV POWER PLANT UNIT TO OPERATE IN PARALLEL WITH GRID
It is important that the solar PV power plant is designed to operate satisfactorily in parallel with the grid under extremely high voltage and frequency fluctuating conditions, so as to export the maximum possible units to the grid.
It is also extremely important to safeguard the system during major disturbances, like tripping / puling-out of big generating stations and sudden overloading during falling of portion of the grid loads on the power plant unit in island mode, under fault / feeder tripping conditions.
Typically, there are few conditions that must be met before synchronization of two AC sources of supply can take place, these are:
