4.

To coordinate the dynamic stability assessments pursuant to Article 38(2) and (4), and to carry them out, each TSO shall exchange with the other TSOs of the same synchronous area or of its relevant part the following data: data concerning SGUs which are power generating modules relating to, but not limited to: electrical parameters of the alternator suitable for the dynamic stability assessment, including total inertia; protection models; alternator and prime mover; step-up transformer description; minimum and maximum reactive power; voltage models and speed controller models; and prime movers models and excitation system models suitable for large disturbances; the data on type of regulation and voltage regulation range concerning tap changers, including the description of existing on-load tap changers, and the data on type of regulation and voltage regulation range concerning step-up and network transformers; and the data concerning HVDC systems and FACTS devices on the dynamic models of the system or the device and its associated regulation suitable for large disturbances.
