Hey Daniel, have you looked at Petri Nets? They are a good way of modelling systems.

Best reagrds, Philipp

I guess it pretty much depends on what you want to "analyse"?

Could you specify some more if you are interested in "structural" information (e.g. network graph properties)? Are you interested in static power quality attributes (voltages, transformer-/line-loadingetc.) or dynamic phenomena?

A big thank you Philipp, I will check the website. Dear Sebastian, I am a beginner.I wish to analyse the power flow of the distribution system. To know how it behaves. Later, I will now look at the option of connecting distributed generators to it to see the changes. It is power flow that I am interested in for now. I hope you can assist me further in kick-starting.Thank you.

Hi Daniel, then I would suggest starting with a simplified DC-model (basically a graph with capacities and line-resistances). You might want to check out this page here for free and easy to use models and simulators:(http://www.openelectrical.org/wiki/index.php?title=Power_Systems_Analysis_Software#Non-Commercial_Software

Additionally, I can recommend PyPower (- https://pypi.python.org/pypi/PYPOWER/4.0.0) which is pretty straight forward, yet already based on an AC-model so you might want to save this for a little later :-).

Hi Daniel,

You may want to take a look at GridLab-D. It is specifically designed to simulate power in distribution networks and has features for renewable energy applications. It is available as open-source / BSD licensing.

or

I would be curious how it works for you. I am also interested in doing some simple power systems analysis.

To effectively use water distribution models, the engineer must be able to link knowledge of basic hydraulic theory and the mechanics of the program with that of the operation of real-world systems.

Advanced Water Distribution Modeling and Management does just that! Written by industry experts, it provides practical resources for engineers and modelers that go well beyond being a how-to guide for typing data into a computer program. The book contains straightforward answers to common questions related both to modeling and to distribution systems in general.

Advanced Water Distribution Modeling and Management walks the practicing engineer or student through the modeling process from start to finish - from data

collection and field-testing to using a model for system design and complex operational tasks.

Advanced Water Distribution Modeling and Management also explores transient analysis, GIS technology applications, and water system vulnerability and security.

The 800-page book includes extensive material from an international team of experts from both academia and consulting firms. Topics include:

A thorough review of water distribution theory

Primary sources of data for building water distribution models

Demand allocation and projection

Energy efficiency evaluation, flushing simulation, and solving operational problems, such as inadequate fire protection

Field testing techniques and model calibration approaches

Identifying and resolving potentially expensive problems, such as undersized piping, inadequate pumping, and poor water quality

Preparing systems for special events, such as power outages, taking tanks offline, and system contamination

Advanced Topics Featured

In-depth coverage of optimization techniques for model calibration, system design, and pump operations.

Advanced water quality modeling topics including tank mixing, water quality solution algorithms, sampling techniques, tracer studies, tank design, and maintenance of adequate disinfectant residuals.

Integration of SCADA systems with water distribution modeling for estimating model demands, initial conditions, and control settings; forecasting system operations; calibrating extended-period simulation models; streamlining water quality analysis; and estimating water loss during a main break.

The essentials of transient analysis including the causes and sources of transients, as well as the potential effects of transients on water distribution systems.

Application of GIS technology for skeletonization, demand allocation, and pipe break analysis; discussion of the technological issues that arise when integrating GIS and water distribution modeling; and the current state of the technology.

Use of models to assess water system vulnerability and security, respond to emergencies in real-time, simulate contamination events, prioritize physical security improvements, and unravel past contamination events.
