Bay Object Advantages
• Decreasing of nodes and branches numbers :
• About 70% of nodes are junctions in substations
• About 75% of branches are switches

Conclusions
 DTS is one from the most complex application in EMS
 It requires huge input data to simulate real power system
– Load flow data
– Protection, automatics and control equipment data
– Dynamic model data
 Creating Bay object is the first step to using CIM
 This way will be long and probably distressful
 But it is useful and perhaps necessary
Thank you for your attention and in advance for help
