Remote License Troubleshooting
If you are trying to start Simulator or Retriever using a remote license but the hardware key is not detected, you may need to manually point to the hardware key’s location on the network. To configure where your machine goes to look for remote license keys, make sure to run the full Simulator or Retriever installation […]

Calculating the Net Reactive Capability Curve of a Renewable Energy Plant and Subsystem
When studying a system of small renewable generators that are all hooked up to the power system through one interconnection point, some PowerWorld users have been interested in calculating the net reactive capability curve seen at the utility interconnection point. As an example consider the power system below which has the following characteristics. Three solar […]

Case Study in Using Auxiliary File Scripting with Advanced Filters, Custom Floats, and Expressions
This is a case study that demonstrates how to automate the process of replicating the net reactive capability curve from a set of renewable generators behind a small distribution system which is connected to a single utility bus. This serves as a wonderful example for demonstrating several topics. Use of auxiliary files to automate processes […]

How to specify when Transient Limit Monitoring starts monitoring for violations
Transient Limit Monitoring Many power systems require particular voltage or frequency performance during transient stability simulation. For example, in the Western grid in the United States and Canada, the organization WECC specifies particular performance for various “Category B” or “Category C” contingency events (see http://www.wecc.biz/library/Library/Planning%20Committee%20Handbook/WECC-NERC%20Planning%20Standards.pdf). PowerWorld Simulator’s transient limit monitors allow you to monitor for violations […]

Updated and Validated Power Flow Model of the Main Continental European Transmission Network
View Paper Authors Abstract The advent of liberalisation of the electricity market in Europe has seen the growth of cross-border trading of energy. Zhou & Bialek published in 2005 a paper outlining an approximate model which simulated the real network and could be used to analyse the effects of cross-border trades in a test environment. This paper presents an […]

Video Capture
PowerWorld Simulator does not include a built-in tool for video capture or movie making. Commercial and freeware tools are available from other sources to capture video from PowerWorld Simulator, Retriever, and any other desktop applications. Current offerings may be found here, or by simply searching online for video capture software.

How do the key fields and required fields for aux files and copy/paste from Excel work?
Each object type in Simulator (i.e. Loads, Generators, Buses, etc…) has a number of key fields and additional required fields. Key fields are fields that must be included for existing records when pasting data into Simulator from a spreadsheet application such as MS Excel or when loading information from an aux file. Required fields are fields that must be specified (in addition […]

Can I solve a Real-Time power flow in Retriever?
Yes. The data that is imported from the real-time sources can be substituted for the underlying system data to solve a real-time power flow in Retriever, provided that: a complete system model with all required object fields necessary to run a power flow solution is provided (see case validation), and the underlying model fields (when […]
