I. Basic PowerFactory Concepts
• The calculation program PowerFactory, as written by
DIgSILENT.
• It is a computer aided engineering tool for the analysis
of industrial, utility, and commercial electrical power
systems.
• It has been designed as an advanced integrated and
interactive software package dedicated to electrical
power system and control analysis in order to achieve
the main objectives of planning and operation
optimization.

I. Basic PowerFactory Concepts
• The name DIgSILENT stands for "DIgital SImuLation
and Electrical NeTwork calculation program''.
• DIgSILENT Version 7 was the world's first power
system analysis software with an integrated
graphical one-line interface.
• That interactive one-line diagram included drawing
functions, editing capabilities and all relevant static and
dynamic calculation features.

I. Basic PowerFactory Concepts
• DIgSILENT power system calculation package was
designed as an integrated engineering tool.
• It provides a complete 'walk-around' technique
through all available functions, rather than a
collection of different software modules.
• PowerFactory Version 14, DIgSILENT represents a
further step towards seamless integration of
functionality and data management within a
multi-user environment.

• There are three basic integration characteristics
that contribute to make PowerFactory a unique
power system analysis tool:
a) Functional integration
c) Vertical integration
b) Database integration

organization of data and definitions required to
perform any type of calculation, memorization of
settings or software operation options.

integrates all data required for defining cases,
operation scenarios, single-line graphics, outputs,
run conditions, calculation options, graphics, user-
defined models, etc.

II.C. Database Integration
• Project Management: All the data that defines a power
system model and allows its calculation is stored in so
called 'Project' folders within the database.
• Inside a 'Project', folders called 'Study Cases' are used
to define different studies of the system considering the
complete network, only parts of it or variations on its
current state.

II.C. Database Integration
• This 'project and study case' approach to define and
manage power system studies is a unique application of
the object-oriented software principle.
• Standard software packages often require the user to
create a large number of similar saved cases, with
multiple nested directories for large complex networks
and studies.
• This approach of the structure is both easy to use while
avoiding redundancy.

Dynamic Modelling with
PowerFactory

Dynamic Modeling with PowerFactory
• Stability analysis calculations are typically based on
predefined system models.
• When no IEEE models exist a powerful tools for
user defined modelling are required.
• For systems and configurations for which no IEEE
models exist, Dynamic Simulation Language
(DSL) could be used
• High specialised and exact models can be created in
PowerFactory.
Seminar:ModellingRenewablesResourcesandStorageinPowerFactoryV15.2

DSL Models
• The Dynamic Simulation Language (DSL) is a powerful
feature of DIgSILENT.
• DSL itself can be looked upon as an add-on to the
transient analysis functionality of PowerFactory.
• During the simulation, the model equations of the DSL
models are combined with those describing the
dynamic behaviour of the power system
components.
• DSL and System equations are then evaluated together,
leading to an integrated transient simulation of the
combination of the power system and its controllers.

3. Types of Dyanmic Models
• Two types of models in DIgSILENT are presented :
1. Built-in models, which are standard electrical component
models, already existing in the DIgSILENT library.
2. DSL models, which are created by the user in the
dynamic simulation language DSL.

DSL Introduction
• The "DIgSILENT Simulation Language" is used to
define new dynamic controllers which receive
input signals from the simulated power system and
which react by changing some other signals.

Types of Wind Power
• Wind Generation Modeling Group (WGMG) of the
Western Electricity Coordinating Council (WECC)
• Working Group on Dynamic Performance of Wind
Power Generation of IEEE Power System
Dynamic Performance Committee
• They have developed and provided specification of
generic wind turbine generator (WTG) models.
• PowerFactory uses IEC 61400-27-1 and WECC
Seminar:ModellingRenewablesResourcesandStorageinPowerFactoryV15.2

IEC 61400-27-1
• This modular structure has many similarities with the
first generation of WECC generic WTG model, but
also some major differences:
– The IEC structure separates the wind turbine
model from the wind plant model
– All the IEC models refer to a common modular
structure which applies for all wind turbine type
models.
– The common structure explicitly separates the
aerodynamic, mechanical, generator-system,
electrical and control modules and adds a grid
protection module.

On the market, this system have been used in Spanish manufacturer Made, GE
multi-megawatt series.
The 2.5 MW Clipper Liberty turbine type, which features four 660 kW PMSGs, has
also used this concept.
Zephyros (currently Harakosan) and
Mitsubishi are using this concept in 2 MW
wind turbines on the market

Introduction
• The fully rated WTG model could be used for:
– Load Flow Studies
– Stability Studies (RMS)
– Transient Studies (EMT)
– Balanced and unbalanced simulations (however control is
implemented for the positive sequence only)
• For dynamic simulation is a variable step size
possible.
• The minimum step size or the fix step size should
be lower than 5ms.

Model Description
• The fully rated WTG is in the single line diagram
represented by a static generator.
• The models of the controllers are collected in the
composite model “FullyRatedConv Control”.
• This composite model could be found either through
the link “Plant Model” on the Basic Data page of the

• All measurement devices are connected either to
the terminal or to the cubicle, which connects the
generator with the terminal.
• This approach ensures that all measurement devices
are correctly connected after entering the model
using the template.

Grid side behaviour depends on:
• Control of the rectifier.
• Used step up transformer.
During fault:
• Low AC voltage on PCC  no power feed in
possible.
• DC voltage is increased up to open-circuit DC
voltage.
• No special protection for solar cell needed.

Battery Energy Storing System
• The template is a generic model for a battery energy
storing system (BESS).
• It represents the grid side converter and the
battery (modelled in DSL).
• The model represents one BESS with a rated
apparent power of 30 MVA it is connected on 10 kV
voltage level.

PF with other models and simulators
• MATLAB: PowerFactory build-in interface (DSL) for co-
simulation
• DLL: Using external DLL in DSL components (e.g.:
TCP/IP sockets) and DPL scripts
• OPC: Industrial standard interface—OPC client—in use
with multi-agent systems and controller hardware in the
loop
• RCOM: Remote communication—remote procedure call
interface for using
• PowerFactory in engine mode (e.g. automated
simulation)
• API: Direct control of PowerFactory internal data model
and advanced functionality (e.g. co-simulation)
• DGS: file format for exchanging data models and
geographical information

DPL Functions Linked to External DLLs
• Similar to the external implemented DSL functions for
dynamic/transient analysis, the DPL interpreter can
be extended by user-defined functions to be used for
steady state analysis

OPC—OLE for Process Communication
• OPC server connects client processes which run
normally in real time such as automation and control
components.
• External data link (ComLink) is a built-in OPC client.

RCOM—Remote Procedure Call
• Until version 14.x, the so-called ENGINE folder was
part of the installation.
• RCOM is well suited for simulation automation since
it is possible to change for instance DPL script
parameters or other model attributes.

API—Application Programming Interface
• Basically, everything you can do in PowerFactory
can be done via the API!!!
• It exposes internal model and objects of the network
data as well as analysis functions and results to be
dynamically linked into any C++ application
environment.
Use of the API in a stand‐alone C++ application

API Python
• Since version 15.1, a Python wrapper for the API
has been provided.
• Since Python is an interpreter based programming
language no compiler is necessary to use the C++
API.
• Python scripts can be directly used within
PowerFactory or used for running the application in
engine mode and controlling it from an external
application

accessing PowerFactory
