Feeder Load Analysis (Segment Level Loading)

Feeder level analysis, also known as Segment Level Loading is a tool that is built for finding the key parameters for a given list of feeders and/or substations.

Key Results:

• Maxmimum demand
• Maximum export
• Minimum usage/export (smallest absolute value that is not zero)

How to run

This guide assumes you have the basic set up configured. For more information on how to set up the basic configuration, see the How to Run a Work Package guide.

1. Clone the repo 'ewb-sdk-examples-python'.

2. As per the readme, install the required dependencies by running the command pip install -e .. If you encounter any issues with installing the dependencies, please talk to your System Administrator for assistance.

3. Open the file request_feeder_load_analysis_study.py in your IDE of choice and modify the parameters to match your needs (see below).

4. Run the file.

Here is an example of a feeder load analysis input that can be used to run the analysis:

class FeederLoadAnalysisInput:
    feeders=["feeder1", "feeder2"],
    substations=None,
    subGeographicalRegions=None,
    geographicalRegions=None,
    startDate="2022-04-01",
    endDate="2022-12-31",
    fetchLvNetwork=True,
    processFeederLoads=True,
    processCoincidentLoads=True,
    aggregateAtFeederLevel=False,
    output="TestResults1"

Configuration Parameters

Field	Type	Description
feeders	[List[str]]	Optional (must have at least 1 of these 4 parameters) - The mRIDs of feeders to solve for feeder load analysis
substations	[List[str]]	Optional (must have at least 1 of these 4 parameters) - The mRIDs of substations to solve for feeder load analysis
subGeographicalRegions	[List[str]]	Optional (must have at least 1 of these 4 parameters) - The mRIDs of sub-Geographical Region to solve for feeder load analysis
geographicalRegions	[List[str]]	Optional (must have at least 1 of these 4 parameters) - The mRIDs of Geographical Region to solve for feeder load analysis
startDate	str	Start date for this analysis
endDate	str	End date for this analysis
fetchLvNetwork	bool	Whether to stop analysis at distribution transformer
processFeederLoads	bool	Whether to include values corresponding to feeder event time points in the report
processCoincidentLoads	bool	Whether to include values corresponding to conductor event time points in the report
aggregateAtFeederLevel	bool	Request for a report which aggregate all downstream load at the feeder level
output	str	The file name of the resulting study
