Hosting Capacity Analysis | ||
========================= | ||
|
||
This section shows how to conduct *hosting capacity analysis* using DISCO pipeline with *snapshot* | ||
and *time-series* models as inputs. This tutorial assumes there's an existing ``snapshot-feeder-models`` | ||
directory generated from the ``transform-model`` command as below. The workflow below can also be | ||
applied to ``time-series-feeder-models``. | ||
|
||
**1. Config Pipeline** | ||
|
||
Check the ``--help`` option for creating pipeline template. | ||
|
||
.. code-block:: bash | ||
$ disco create-pipeline template --help | ||
Usage: disco create-pipeline template [OPTIONS] INPUTS | ||
Create pipeline template file | ||
Options: | ||
-T, --task-name TEXT The task name of the simulation/analysis | ||
[required] | ||
-P, --preconfigured Whether inputs models are preconfigured | ||
[default: False] | ||
-s, --simulation-type [snapshot|time-series|upgrade] | ||
Choose a DISCO simulation type [default: | ||
snapshot] | ||
--with-loadshape / --no-with-loadshape | ||
Indicate if loadshape file used for Snapshot | ||
simulation. | ||
--auto-select-time-points / --no-auto-select-time-points | ||
Automatically select the time point based on | ||
max PV-load ratio for snapshot simulations. | ||
Only applicable if --with-loadshape. | ||
[default: auto-select-time-points] | ||
-d, --auto-select-time-points-search-duration-days INTEGER | ||
Search duration in days. Only applicable | ||
with --auto-select-time-points. [default: | ||
365] | ||
-i, --impact-analysis Enable impact analysis computations | ||
[default: False] | ||
-h, --hosting-capacity Enable hosting capacity computations | ||
[default: False] | ||
-u, --upgrade-analysis Enable upgrade cost computations [default: | ||
False] | ||
-c, --cost-benefit Enable cost benefit computations [default: | ||
False] | ||
-p, --prescreen Enable PV penetration level prescreening | ||
[default: False] | ||
-t, --template-file TEXT Output pipeline template file [default: | ||
pipeline-template.toml] | ||
-r, --reports-filename TEXT PyDSS report options. If None, use the | ||
default for the simulation type. | ||
-S, --enable-singularity Add Singularity parameters and set the | ||
config to run in a container. [default: | ||
False] | ||
-C, --container PATH Path to container | ||
-D, --database PATH The path of new or existing SQLite database | ||
[default: results.sqlite] | ||
-l, --local Run in local mode (non-HPC). [default: | ||
False] | ||
--help Show this message and exit. | ||
Given an output directory from ``transform-model``, we use this command with ``--preconfigured`` option | ||
to create the template. | ||
.. code-block:: bash | ||
$ disco create-pipeline template -T SnapshotTask -s snapshot -h -P snapshot-feeder-models --with-loadshape | ||
.. note:: For configuring a dynamic hosting capacity pipeline, use ``-s time-series`` | ||
It creates ``pipeline-template.toml`` with configurable parameters of different sections. Update | ||
parameter values if needed. Then run | ||
.. code-block:: bash | ||
$ disco create-pipeline config pipeline-template.toml | ||
This command creates a ``pipeline.json`` file containing two stages: | ||
* stage 1 - simulation | ||
* stage 2 - post-process | ||
Accordingly, there will be an output directory for each stage, | ||
* output-stage1 | ||
* output-stage2 | ||
**2. Submit Pipeline** | ||
With a configured DISCO pipeline in ``pipeline.json`` the next step is to submit the pipeline with | ||
JADE: | ||
.. code-block:: bash | ||
$ jade pipeline submit pipeline.json -o output | ||
What does each stage do? | ||
* In the simulation stage DISCO runs a power flow simulation for each job through PyDSS and stores | ||
per-job metrics. | ||
* In the post-process stage DISCO aggregates the metrics from each simulation job, calculates | ||
the hosting capacity, and then ingests results into a SQLite database. | ||
**3. Check Results** | ||
The post-process stage aggregates metrics in the following tables in ``output/output-stage1``: | ||
* ``feeder_head_table.csv`` | ||
* ``feeder_losses_table.csv`` | ||
* ``metadata_table.csv`` | ||
* ``thermal_metrics_table.csv`` | ||
* ``voltage_metrics_table.csv`` | ||
Each table contains metrics related to the *snapshot* or *time-series* simulation. DISCO | ||
computes hosting capacity results from these metrics and then writes them to the following files, | ||
also in ``output/output-stage1``: | ||
* ``hosting_capacity_summary__<scenario_name>.json`` | ||
* ``hosting_capacity_overall__<scenario_name>.json`` | ||
The scenario name will be ``scenario``, ``pf1`` and/or ``control_mode``, depending on your | ||
simulation type and/or ``--with-loadshape`` option. | ||
Note that DISCO also produces prototypical visualizations for hosting capacity automatically after each run: | ||
* ``hca__{scenario_name}.png`` | ||
.. image:: ../images/hca__pf1.png | ||
:scale: 60 | ||
The voltage plot examples for the first feeder comparing pf1 vs. voltvar and comparing primary and secondary voltages: | ||
* ``max_voltage_pf1_voltvar.png`` | ||
* ``max_voltage_pri_sec.png`` | ||
.. image:: ../images/max_voltage_pri_sec.png | ||
:scale: 60 | ||
**4. Results database** | ||
DISCO ingests the hosting capacity results and report metrics into a SQLite database named | ||
``output/output-stage1/results.sqlite``. You can use standard SQL to query data, and perform | ||
further analysis. | ||
If you want to ingest the results into an existing database, please specify the absolute path | ||
of the database in ``pipeline.toml``. | ||
For sqlite query examples, please refer to the Jupyter notebook ``notebooks/db-query.ipynb`` in | ||
the source code repo. | ||
If you would like to use the CLI tool ``sqlite3`` directly, here are some examples. Note that in | ||
this case the database contains the results from a single task, and so the queries are not first | ||
pre-filtering the tables. | ||
If you don't already have ``sqlite3`` installed, please refer to their | ||
`website <https://www.sqlite.org/download.html>`_. | ||
Run this command to start the CLI utility: | ||
.. code-block:: bash | ||
$ sqlite3 -table <path-to-db.sqlite> | ||
.. note:: If your version of sqlite3 doesn't support ``-table``, use ``-header -column`` instead. | ||
1. View DISCO's hosting capacity results for all feeders. | ||
.. code-block:: bash | ||
sqlite> SELECT * from hosting_capacity WHERE hc_type = 'overall'; | ||
2. View voltage violations for one feeder and scenario. | ||
.. code-block:: bash | ||
sqlite> SELECT feeder, scenario, sample, penetration_level, node_type, min_voltage, max_voltage | ||
FROM voltage_metrics | ||
WHERE (max_voltage > 1.05 or min_voltage < 0.95) | ||
AND scenario = 'pf1' | ||
AND feeder = 'p19udt14287'; | ||
3. View the min and max voltages for each penetration_level (across samples) for one feeder. | ||
.. code-block:: bash | ||
sqlite> SELECT feeder, sample, penetration_level | ||
,MIN(min_voltage) as min_voltage_overall | ||
,MAX(max_voltage) as max_voltage_overall | ||
,MAX(num_nodes_any_outside_ansi_b) as num_nodes_any_outside_ansi_b_overall | ||
,MAX(num_time_points_with_ansi_b_violations) as num_time_points_with_ansi_b_violations_overall | ||
FROM voltage_metrics | ||
WHERE scenario = 'pf1' | ||
AND feeder = 'p19udt14287' | ||
GROUP BY feeder, penetration_level; | ||
4. View the max thermal loadings for each penetration_level (across samples) for one feeder. | ||
.. code-block:: bash | ||
sqlite> SELECT feeder, sample, penetration_level | ||
,MAX(line_max_instantaneous_loading_pct) as line_max_inst | ||
,MAX(line_max_moving_average_loading_pct) as line_max_mavg | ||
,MAX(line_num_time_points_with_instantaneous_violations) as line_num_inst | ||
,MAX(line_num_time_points_with_moving_average_violations) as line_num_mavg | ||
,MAX(transformer_max_instantaneous_loading_pct) as xfmr_max_inst | ||
,MAX(transformer_max_moving_average_loading_pct) as xfmr_max_mavg | ||
,MAX(transformer_num_time_points_with_instantaneous_violations) as xfmr_num_inst | ||
,MAX(transformer_num_time_points_with_moving_average_violations) as xfmr_num_mavg | ||
FROM thermal_metrics | ||
WHERE scenario = 'pf1' | ||
AND feeder = 'p19udt14287' | ||
GROUP BY feeder, penetration_level; |
