Play-in time series measurement data with PlayInGen model for Power Plant Model Validation (PPMV)

PlayIn models can be found in the Transient Stability add-on of Simulator. Many dynamic models comprise of differential-algebraic equations that respond to perturbations in a simulation. In contrast, these PlayIn models are used to input time-series data into a transient run at specified time points. In Simulator, a PlayIn Configuration object can be used to store […]

Adding Voltage Compensation to a Generator Model

Generator Voltage Compensation The input signal to Exciter models is a voltage signal (often labeled as either Vc or Ec on a block diagram).  In the simplest form this is just the per unit voltage magnitude of the terminal bus of the generator.  However, sometimes instead of using that voltage signal directly, the voltage is compensated by attempting to control […]

EMP Simulation Example

NOTE: This example requires PowerWorld Simulator version 20 beta. Please contact us if you are interested in testing and evaluating this software. PowerWorld is developing the capability to analyze the E3 effects of a high-altitude electromagnetic pulse (HEMP) attack on the power system. Algorithms are based on Oak Ridge National Laboratory research. To perform a sample […]

Using Contingency Categories for monitoring of different voltage deviation limits for different contingencies

Previous knowledge base articles have covered both Monitoring voltages for Post Contingency Voltage Drop Criteria Monitoring which covered how to monitor all buses in the system for a particular voltage drop. How to specify different Voltage Deviation Limits for different buses in Contingency Analysis which did a similar thing but allowed the criteria to be […]

Optimal Power Flow with Load Dispatch

Download the example files. These examples show how Simulator’s Optimal Power Flow (OPF) may be used with dispatchable loads to relive transmission overloading. First, the OPF may be used with the minimum control change objective function. Here, the “cost” of changing a control (generator or load output) is the same for each MW of change […]

Interactive Tutorial

This tutorial features a fictitious power system the size of a medium-sized city. The simulations explore several facets of power system planning and operations, including: addition or removal of transmission facilities addition, de-rating, or removal of generating resources demand response and use of customer-owned generation, such as rooftop solar physical or cyber attack on a […]
