A modelica power system library for phasor time-domain simulation

Abstract

Abstract-Power system phasor time-domain simulation is often carried out through domain specific tools such as Eurostag, PSS/E, and others. While these tools are efficient, their individual sub-component models and solvers cannot be accessed by the users for modification. One of the main goals of the FP7 iTesla project [1] is to perform model validation, for which, a modelling and simulation environment that provides model transparency and extensibility is necessary.1 To this end, a power system library has been built using the Modelica language. This article describes the Power Systems library, and the software-to-software validation carried out for the implemented component as well as the validation of small-scale power system models constructed using different library components. Simulations from the Modelica models are compared with their Eurostag equivalents. Finally, due to its standardization, the Modelica language is supported by different modelling and simulation tools. This article illustrates how Modelica models can be shared across different simulation platforms without loss of information and maintaining consistency in simulation results.

CIM-Compliant Power System Dynamic Model-to-Model Transformation and Modelica Simulation

“…Modelica is an object-oriented equation-based programming and modeling language, which allows the representation of cyber-physical systems using a strict and openly standardized mathematical representation for dynamic modeling and simulation. The authors' previous works in the FP7 iTESLA project has used Modelica for power system modeling [4][8] [17][18][19][20], and Modelica-compliant tools have been used for simulations and compared with proprietary simulation tools [17][18][19]. One result of this project is the Modelica library containing dynamic for power systems component models [3], the OpenIPSL.…”

Novel Simulation Approaches for Smart Grids

“…The library includes models for different elements of a power system including power generation, transmission lines, loads, transformers, capacitor banks etc. [31].…”

“…There is an emerging use of the multi-domain Modelica modeling language for power system simulations (e.g., in [31,32]). The language can be also used for the modeling of buildings and of control systems.…”

Equation-based modeling of FACTS using Modelica

“…Some examples of OSS are UWPFLOW [9], PSAT [10], PowerWeb [11], ObjectStab [12]. However, some of these are no longer supported and/or incompatible with the language's compiler [13].…”
