Simulation Software

MATLAB/Simulink (Institute licence)

MATLAB is a multi-disciplinary numerical computing software and simulation environment. It serves as a solution platform for several Power system applications such as:

  • Modelling of electrical circuits and networks
  • Modelling of wind energy systems, battery energy storage system etc.
  • Design and control of power electronic converters
  • Microgrid applications
  • Wind generation, solar generation and electricity price forecasting

PSCAD (20 Licences)

PSCAD is computer-aided design software used to model and simulate electrical power systems. This software has huge applications in short circuit analysis, modelling of electrical substations, HVDC systems and power system protection algorithms.


CYMDIST Distribution Analysis software (5 users)

CYMDIST is powerful distribution network analysis tool having the feature of performing the load flow analysis of balanced, unbalanced, single phase, three-phase, mesh type or radial type network very effectively and efficiently.

PS&SG lab uses the software to analyse the IITGN distribution network which has highly unbalanced and seasonally varying load pattern with a 500KW solar power plant


OpenDSS (Open source)

OpenDSS is a multipurpose distribution analysis tool to support all distribution planning aspects of distributed generation. The distribution system is analysed in frequency domain for power flow, harmonic analysis and distribution dynamic analysis.

In PS&SG Lab, OpenDSS is used to study the behaviour of the IITGN distributed network which has a 500KW solar power injection. It is also used to perform time series analysis of the network subjected to the seasonally varying load pattern.


GAMS (Student version)

General Algebraic Modelling System (GAMS) is used to solve the linear, non-linear and mix-integer optimization problems.
