Phasor Time-Domain Power System Modeling and Simulation using the Standardized Modelica Language: Conventional and Power Electronic-Based Devices
Mohammad Ahsan Adib Murad · 2015
Modern electric power systems are complex networks that ensure continuous supply ofelectricity. For the planning and operation of these complex networks, modeling and simulationsare essential to satisfy operational requirements or planning constraints. Traditionally,dynamic modeling and simulation of power systems is performed by usingdi erent and mostly incompatible software packages. This issue is currently being addressedthrough the Common Information Model (CIM) for power system applications,however, there are still many challenges for Power system dynamic modeling and simulationwithout any ambiguity.To overcome these challenges, this thesis develops unambiguous models for consistentmodel exchange, which are compatible in di erent simulation environments that supportthe Modelica language. Modelica, an object-oriented equation-based standardizedlanguage, is proposed as possible solution to these challenges as it can represent andexchange dynamic models with a strict mathematical description.In this thesis, modeling and simulation of controllable power electronic-based componentsand conventional components for phasor time-domain simulation is carried outusing Modelica. The work in this thesis contributes to a Modelica power systems librarybeing developed by KTH SmartTS Lab under the FP7 iTesla project and other projectssupported by Statnett SF. Both software implementation in Modelica of each component,and software-to-software validation against PSAT is carried out.
