Backcasting and Calibration

This section discusses how backcasting is performed, including the inputs, outputs, and the steps involved.

Use and Purpose

Backcasting involves modeling historical load data to improve the accuracy of future forecasts. Before doing this, a historical load must first be completed.

Prerequisites

  • Historical Demand
  • Historical Generation
  • Historical Bids
  • Historical Events

Step-by-Step Guide

Inputs

Prepare to include the Event File, Region Demand, and Must Run Generation files from the previous historical load. These files are generated automatically and follow these naming conventions:

  • Event File: Ev_[HistoricalLoadFileName].csv
  • Region Demand: Demand_[HistoricalLoadFileName].csv
  • VRE Generation: MRGCFac_[HistoricalLoadFileName].csv
note

Use the hourly data (DemandHR_xxxx.csv and MRHCFac_xxxx.csv) if the time interval needed is hourly instead of 5-minute.
