# ALLSHIFT

> Umbrella repository for **Team SHIFT** — an AI-driven hydrogen microgrid energy-management system for hospitals.

ALLSHIFT is the central hub that ties together the team's repositories, models, data, and planning documents. It links the four clusters — **Energy Management**, **Simulations**, **Business & Economics**, and **AI & Control Systems** — under one roof.

## Mission

Accelerate the transition to resilient, low-carbon energy systems through AI-driven energy management. We develop intelligent control for critical infrastructure that optimizes renewables, storage, hydrogen technologies, and grid interaction — improving reliability, reducing emissions, and increasing efficiency where uninterrupted power matters most.

Founded in 2021 at the TU/e Innovation Space and Neuron (Eindhoven). Case studies: Beth Israel Deaconess Medical Center (BIDMC) and UC San Diego (UCSD).

## The challenge

Hospitals need reliable, uninterrupted power while the grid grows more congested, less predictable, and more weather-dependent. With the Dutch "balancing system" being phased out from 2025, energy returned to the grid is only partially compensated. SHIFT answers with an AI-driven hydrogen microgrid that forecasts hospital demand, optimizes solar and battery use, and controls electrolyzers and fuel cells so every component runs at its full potential.

```

**Dispatch priority cascade:** PV → battery → hydrogen (fuel cell discharge / electrolyser charge) → external grid. Critical hospital load is always prioritised ("critical load is sacred").

## Clusters

- **Energy Management** — hospital load characterisation, PV/solar data, datasets and manuals.
- **Simulations** — MATLAB/Simulink physical models: PEM electrolyser, PEM fuel cell, hydrogen storage, battery, gravity storage; the dispatch controller.
- **Business & Economics** — cost and CO₂ accounting, viability analysis.
- **AI & Control Systems** — forecasting stack and the RL/rule-based control policy.

## Key planning documents

- **Forecasting requirements** — specs for three forecasters:
  - *PV generation* — LightGBM + Temporal Fusion Transformer ensemble; inputs from KNMI NWP, solar position, clear-sky index.
  - *Hospital electricity demand* — TFT primary, LightGBM/XGBoost ensemble; ASHRAE Guideline 14 metrics.
  - *Day-ahead electricity price* — LEAR baseline → NBEATSx / DNN / TFT → ensemble.
  - Methodology: rolling walk-forward cross-validation, post-2022-crisis training data, readiness for the Oct 2025 15-minute market units (24 → 96 outputs/day).
- **Simulator Interface Input/Output sheet** — the typed contract between the simulator and everything that talks to it (controller, validation layer, economics): conventions, static config, per-timestep inputs/setpoints, outputs and KPIs, priority rules.

## Status

Early development. Physical models and planning specs are in place; the simulator environment, forecasters, and control policy are being built out.
