The study reveals the need for further investigations into the IPS/UPS in order to refine and endorse the recognized measures and requirements. Major areas identified for further studies are:
The verification of the IPS/UPS dynamic performance by means of observations being carried out over a longer period. It should be followed by a dynamic model set-up using a parameter identification for the control device models. This allows in-depth simulations on advanced dynamic models that are able to ensure reliable simulation results.
The analyses of emergency situations in the IPS/UPS caused by severe disturbances that have not been experienced by the system up to now. It is recommended that a simulation model is prepared which sequentially simulates the control automatics and functions after severe disturbances, as well as any necessary restoration measures. The purpose of this would be to adapt and harmonize the current existing operational guidelines, defence and restoration plans for both synchronous areas.
The analyses of technical and organisational aspects within the IPS/UPS based on the assumption that several control blocks may eventually operate in the IPS/UPS, compared with the single control block status at the present time. As the load flow distribution in the interface area is very sensitive to the generation pattern, the distribution of the control reserve may significantly influence the viable power transfers.
