Overview

This section covers the use of Event Files in Dashboard, including:

Event Files​

Event Files are used to simulate temporary or permanent changes to the power system during a simulation. They allow users to modify the characteristics of specific system objects without permanently changing the system database.

Rather than editing the database itself, an Event File applies changes only for the duration specified within the event. This enables users to model planned outages, transmission constraints, renewable curtailments, capacity adjustments, demand changes, and other operational scenarios while preserving the integrity of the original database.

Event Files are commonly used during Historical Load, Backcasting, Forecasting, and What-if studies.

Event files can be created using the Event Builder in Event Hub (GUI path) or by editing the CSV file directly. See Creating an Event File for both workflows.

After completing this section, users should be able to:

  • Understand the purpose of Event Files.
  • Create a new Event File using the Event Builder or direct CSV edit.
  • Understand the required Event File fields.
  • Apply Events to different system objects.
  • Configure common operational scenarios.
  • Create Event Sets for multiple Event Files.
  • Execute Event Files through Dashboard or batch files.

Common Applications​

Event Files are frequently used to simulate operational changes that affect market dispatch and system performance.

  • Generator Outages Temporarily remove generating units from service by reducing their available capacity during a specified time period.

  • Transmission Constraints Restrict power flow across transmission interconnections such as VISLUZ1 and MINVIS1. This allows users to study congestion, regional price separation, and transmission bottlenecks.

  • Renewable Curtailment Increase or decrease the available capacity of renewable technologies such as Solar, Wind, and Hydro. This is commonly used for sensitivity studies and renewable integration analysis.

  • Market Studies Modify simulation parameters such as Short Run Marginal Cost (SRMC), Bid Prices, Bid Quantities, Demand, and Carbon Cost without permanently modifying the system database.
