Overview

This section discusses what a zonal configuration is and how to set it up.

Zonal Configuration​

This feature allows for more granular network analysis by breaking the main grid into smaller sub-regions.

iPool vs. WESM Terminology​

Before creating a zonal database, it's crucial to understand the "opposite convention" for naming between iPool and WESM:

  • iPool Convention:
    • Zones: The 3 large areas (Luzon, Visayas, Mindanao).
    • Regions: The 14 smaller sub-regions (what WESM calls zones).
  • WESM Convention:
    • Regions: The 3 large areas.
    • Zones: The 14 smaller sub-regions.

Why the difference? iPool calculates flow between regions (the 14 smaller areas), hence its naming choice.

How to Create a Zonal Database​

Follow the phases below to convert your conventional database into a zonal database.

Copy the Database​

Make a copy of your existing database (e.g., SysWESM25T.mdb) and give it a new name to serve as your zonal database (e.g., SysWESMZONES.mdb).

copy /y .\Databases\SysWESM25T.mdb .\Databases\SysWESMZONES.mdb
note

SysWESMZONES.mdb is the dedicated database used for your new zonal configuration.
