Power Flow Studies for Assessment the Security of Steady States in Zone Inside the Large Interconnected Power System

The use of PLANS and NetworkX in modeling power grid system failures

“…The nowadays progress in power engineering modeling and simulation is supported by computer packages that allow finding stable and critical system states specified by interconnected power system (IPS) setups combining many individual operating electric power systems (EPS). The main goal of such activity is the improvement of power supply reliability 1 , to provide high electric energy quality for consumers 2 , to find more efficient use of available power-generating system capacity 3 . The increasing number of such grids elements (transmission lines, transformers, generators, nodes, etc.)…”

“…One can observe a paradigm shift from individual manual made calculations with the use of simple software to more complex software solutions designed for operation analysis tasks dispatch management decision-making. The automation of calculations allows solving many important problems related to RA because the maximum number of significant element outages in IPS’s is not always known, thus the focus on systems reliability analysis only having the utmost combination of dead elements is infeasible 3 . A large sequence of calculations to determine RA of IPS cannot be implemented without the support of advanced computer technology and among known solutions we can indicate: PLANS 10 , GridLAB-D 11 , PowerWorld 12 , SYNDIS 13 , GE Positive Sequence Load Flow Software (GE-PSLF) 14 , NEPLAN 15 .…”

“…The IEEE118-Bus Test Case data was entered to computer systems manually and ” made available to the electric utility industry as a standard test case ” 3 . It was primarily in PECO PSAP format (entered by Rich Christie, researcher at University of Washington in 1993) 20 .…”
