Types of Scenarios You can modify: System demand (increase or decrease) Generator availability (outages) Transmission lines (constraints or outages) Market conditions (bids, reserves)

The following scenarios are used to validate cost-based dispatch logic and administered pricing configurations.

General Execution Steps

1

Configure Must-Run Status

  Set to Must-Run all HYDRO, ROR, SOLAR, WIND, GEO, and BIO in the SysWESM2026CB.mdb Cost-Based DB.

2

Optimize Energy Limited Plants (ELP)

  Optimize ELP with Load, specifically focusing on KALAYAAN and some BAT (Battery) sites.

3

Calibrate Capacity Factors

  Set the %Target CapFac of ELPs according to historical data.

4

Adjust Demand Subtraction

  Set ExcPS = 0 in Defaults.csv to NOT subtract the dispatchable demand from the Region demand. This allows iPool to schedule optimized dispatch of the Pump and Battery storages independently.

5

Define Price Caps

  Set the following price caps for thermal plants in the Defaults.csv file:

• PrcCapCOAL,6000
• PrcCapCCGT,0

Market Scenarios

Scenario ID	Description
BASE	Cost-Based Defaults: Sets the defaults (start date, days, dispatch resolution, options) using SysWESM2603CB.mdb. Includes Must-Run settings for SOLAR, WIND, BIO, HYDRO, GEO, ROR, and some BAT. BESS_CLUZ and BESS_CVIS storages are added containing BAT sites with Load/Demand energy in historical.
HCB	Historical Cost-Based: Historical scenario run utilizing the SysWESM2603CB.mdb database.
CST	5-Min Cost-Based Dispatch: Cost-based scenario using SysWESM2603CB.mdb with optimized ELP operation. • -cost 1 turns ON cost-based simulation. • -opELP ALL optimizes ALL energy limited plants (pump storage and BESS) operation by leveling the net system demand (duck curve).
CSTH	Hourly Cost-Based Dispatch: Hourly dispatch cost-based scenario using SysWESM2603CB.mdb plus optimized ELP Storages: KALAYAAN, BESS_CLUZ, and BESS_CVIS.
CSTHap3	Administered Pricing (Flat 3k): Uses administered prices from APrices3.csv applied to ALL Regions, Links, and Sites (but not contracts). • -p APrices3.csv sets prices at a flat 3000 for demo testing.
CSTHap5	Administered Pricing (Flat 5k): Uses administered prices from APrices5.csv. • -p APrices5.csv sets prices at a flat 5000 for demo testing.
CSTHapX6	Profiled Administered Pricing: Uses administered prices from APricesX.csv applied to ALL. • -p APricesX.csv sets profiled prices. • PrcCapCOAL = 6000 set in Defaults.csv.
CSTHapX0	Profiled Pricing (Zero Cap): Uses administered prices from APricesX.csv with PrcCapCOAL = 0 set in Defaults0.csv.
CSTHap5EERI	Portfolio-Specific Pricing: Uses administered prices from APrices5.csv, BUT applied to all Regions, Links, and only to Sites of the EERI portfolio. • -port EERI targets the specific portfolio.
