A 2 day training was provided in Ankara for 16 people from TEIAŞ and 1 from Tübitak. As the Battery integration with DIgSILENT PowerFactory training report sums up the key messages and discussions of the training, we melt in this section the description of these 2 deliverables.

Exercise 6 (optional): BESS model integration into the model of Turkish power system

Demonstration of generic BESS model integration into the Turkish power system dynamic model (if available) and running various kinds of analyses.

During the training a lot of interesting discussion was raised. The training attendees were interested in modification of the number of battery cells within the overall BESS model. It was explained that generic BESS model which is available in DIgSILENT global library has the possibility to change the number of cells which are connected in series and in parallel branches. It was also demonstrated that by modifying the number of cells in parallel branches total BESS energy capacity can be changed.

During the exercise part of the training, it was demonstrated how different BESS models can provide additional active power support during frequency deviations caused by system disturbances. It was discussed during the training that required BESS characteristics can be determined by knowing the particular system limitations in terms of allowed frequency dip which defines required BESS power capacity and minimum time necessary for starting the units in reserve which defines required BESS energy capacity.

In the second day of the training an exercise of BESS grid integration was performed on the Turkish power system model. BESS generic model was connected to the substation in the Turkish power system where TEIAŞ plans to implement a storage system. A reference outage of 150 MW synchronous generator was simulated in case without and in case with BESS connected to the transmission grid. Attendees could observe the difference in frequency deviation between the two cases.

One of the trainees raised the question related to the possibility of sharing the BESS model between different projects within DIgSILENT PowerFactory. It was explained and demonstrated that PowerFactory allows sharing all object data between different projects, among which also the BESS generic model template. This was demonstrated by copying one of the BESS generic models from the exercise project to Turkish power system project.

1.4. Satisfaction survey results

In order to measure the satisfaction of the participants to the training, and improve future training sessions, the attendees were asked to fill out a satisfaction survey.

Figure 2 Entities of the participants who attended the training

In total 12 people out of the 14 training participants answered this survey. We can consider that the answers are representative of the global opinion. It can be considered that the attendees are globally satisfied.

Average opinion is 8.9 for the complete training.

1.4.1. Global satisfaction of the attendees about this training

Most of the participants gave their opinion. They were globally satisfied (8.9 /10).

All participants from TEIAŞ filled in the auto-evaluation form regarding their own experience in DIgSILENT PowerFactory. It was discussed during the training that among the participants there were a few training attendees with basic knowledge in DIgSILENT PowerFactory. Since the topic of the training requires advance knowledge in usage of DIgSILENT PowerFactory, a couple of the attendees had difficulties in understanding some parts of the training. Some of the participants would have wished that the training could last more than two days during which some basics of DIgSILENT PowerFactory could also be explained.
