+# 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.
