Optimized Energy Limited Plants (opELP)

This section covers how to utilize the opELP feature for simulating Battery Energy Storage Systems (BESS) within the iPool environment.

What is opELP?

Optimized Energy Limited Plants (opELP) is a command-line optimization tool designed to levelize the net system demand. Unlike price-based bidding, opELP focuses on the physical demand curve to improve grid stability.

Operational Logic

The algorithm operates the BESS units based on system load profiles:

• Charging: Occurs during "valleys" or periods of low peak demand.
• Discharging: Occurs during high peak periods, typically during the evening ramp-up.

Goal

The primary objective of opELP is to flatten the net system demand, reducing the stress on peaking power plants.

note

To enable this feature, you do not need to modify and create individual unit bids manually. It is activated via a commandline in your simulation batch file.

Step-by-Step BESS Simulation

• Phase 1: Inputs Preparation
• Phase 2: Initialize and Run
• Phase 3: Compare and Analyze

1

Storages File (Storages.csv)

Define the high-level details of the new BESS. This file is located at "C:\IENERGY\WESM25XX\Databases".

• Key Parameters: ID, Region, Maximum and Minimum Capacity, and Starting Storage Percentage.

2

Sites File (Sites.csv)

Define the specific site details and link them to the main storage ID. This file is located in the same Databases folder.

• Key Parameters: Site ID, Region, Costs, Efficiency, and the associated StorID.

3

Units File (Units.csv)

Define the individual battery units and link them to their respective site. This file is also located in the Databases folder.

• Key Parameters: Unit ID, Region, Costs, Efficiency, Maximum/Minimum Capacity, and the associated SiteID.

note

All other parameters should be kept identical to the template.
