Abstract

Implementation of the bus coupler outage scenarios in the NetVision DAM energy management system (EMS) contingency analysis is presented in this paper. In order to identify the bus coupler branches in the network model, the existing topology processor was upgraded. The description of the topological algoritm for detection of the bus couplers is given. Based on the toppology analysis results, calculation subnodes are created. Calculation model was modified in order to include the bus couplers and the subnodes as the new calculation objects. These modifications are fundamental for the introduction of the bus coupler outages in the contingency analysis. Implications of the bus coupler outages on the load flow mathematical model are discussed. Implemented NetVision DAM solution for the analysis of such outage scenarios is presented.
