Feeder Load Analysis (Segment Level Loading)

Feeder Load Analysis, also known as Segment Level Loading, is a tool for finding key parameters for a given list of feeders and/or substations.

For each feeder segment, the tool reports:

• Maximum 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 pip install -e .. If you encounter any issues, please contact Zepben support.

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:

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 include the LV network in the analysis
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
