## Folder contents

| File | Size | Format | What it is |
|---|---:|---|---|
| `Shift Powerworld Microgrid EASI.mp4` | **10.9 MB** | MP4 video | Screen recording / demonstration of the model — see [The video](#the-video) |
| `microgrid_OG.PWB` | 28 kB | PowerWorld Binary | The **case file** — the actual network model (buses, lines, generators, loads) |
| `final_base_v5.tsb` | 14 kB | PowerWorld Time Step Base | Time-step simulation definition — `v5` implies at least five iterations |
| `microgrid_OG.pwd` | 5.6 kB | PowerWorld Display | The one-line diagram / display layout for `microgrid_OG.PWB` |
| `Profiles SHIFT(Generators Factors + Battery).csv` | 9 kB | CSV | Input profile — see [The CSV](#the-csv-input-profile) |

`.PWB`/`.pwd`/`.tsb` are proprietary PowerWorld Simulator formats. They are **binary and
unreadable without a PowerWorld licence**, and nothing in this repository records which
PowerWorld version or licence tier is required to open them.

> [!NOTE]
> `microgrid_OG` — "OG" reads as *original*. `final_base_v5.tsb` carries both "final" and "v5".
> The two naming schemes do not agree about which artefact is the settled one. The `.tsb`
> version number is the only explicit version marker anywhere in this folder.

## The CSV input profile

`Profiles SHIFT(Generators Factors + Battery).csv` is a **semicolon-delimited, comma-decimal**
export — European locale — of the first sheet of the
[Generation Profiles Workbook](generation-profiles-workbook.md).

```
;Solar Capacity Factor;Wind Capacity Factor;Max Power PV (MW);Max Power Wind;Actual Pv Power (MW);Actual Wind Power (MW);Min Power (MW)
00:00;0;0,448;151,095442;2;0;0,896;0
01:00;0;0,462;151,095442;2;0;0,924;0
...
```

The values match the workbook exactly — 151.095442 MW max PV, 2 MW max wind, the same hourly
capacity factors. It is a **derived export, not an independent source**: 24 hourly rows,
followed by trailing empty columns from the spreadsheet's used range.

This closes the loop on where the workbook's *"Results Analysis"* section came from — the
workbook supplies the generation profile to PowerWorld via this CSV, PowerWorld runs the
time-step study, and the results are pasted back into the workbook.

> The decimal-comma format means this CSV will parse incorrectly under a default (US-locale)
> reader. `PVBatteryRead.mlx` handles exactly this case for the `.xlsx`
> (`col = strrep(col, ',', '.')`), but nothing in the repository reads this CSV programmatically.

## What the model shows

The findings from the PowerWorld run are recorded in the workbook rather than here, and are
reproduced in
[Generation Profiles Workbook → PowerWorld results analysis](generation-profiles-workbook.md#powerworld-results-analysis).
In summary:

- No major voltage problems; generators work as intended.
- The grid does not pull energy when the battery is active, but pulls more when the battery is
  also pulling — the recommendation is shorter, stronger midday charge cycles and night-time
  discharge.
- **The line/transformer is overloaded in 19 of 24 hours**, peaking at **428% of MVA limit**.
  The workbook's own conclusion is that the line rating and distance data are unrealistic
  rather than the dispatch being wrong.

That unresolved line-rating question is the main open item for this model.

## Scale

This model runs at **151 MW PV / 140 MWh storage / 600 MWh per day** — campus or
distribution-network scale, roughly 300× the single-hospital scale used everywhere else in the
project (a 2,300 m² rooftop array is ~0.46 MW peak). It is closer to the
[UCSD campus microgrid](../03-energy-management/ucsd-equipment-manual.md) (30 MW CHP) than to
BIDMC.

Whether that is deliberate — a network-level study to complement the building-level Simulink
work — or an uncorrected placeholder is not recorded anywhere. Worth a note in the folder.

## The video

`Shift Powerworld Microgrid EASI.mp4` (10.9 MB) is the **third-largest file in the repository**
and the only video. Its content cannot be transcribed into this report — it is a screen
recording, and no accompanying description exists.

**Recommendation, not yet applied:** a 10.9 MB binary video in git is the kind of file that is
better hosted alongside the team's other media (ClickUp, Drive, or the website) with a link
from here. If it is a demo of the model running, a few captioned screenshots plus a paragraph
would serve the repository better and cost ~100 kB. Left in place pending the team's decision —
deleting the only recording of a model nobody can open without PowerWorld would be the wrong
call to make unilaterally.
