MMS Optimization & Rules EngineLoad-Shed Staging · BESS Arbitration

Decision Engine

Pre-charges the 1,500 kWh BESS to 85% ahead of the storm and locks the 1,080 kW clinical protected floor. If the grid fails, battery + Hover wind carry it: ~90 min of reserve vs ~71 min without Hover (1,000 kW battery max is below the floor).

Agentic Governance

Agent Reasoner: Explains decision logic ("Zero clinical impact in acute care; sheds 215 kW cooling & noncritical pump loads in Buildings B & C").

Operator Execution: One-click approval commits BMS commands, secures the 1,080 kW floor for the grid outage, and sends WO to Maximo.

MMS Rules & Optimization Engine

Microgrid Management System (MMS)

Deterministic constraints, reserve arbitration, & load-shed orchestration

REST / Event Streams (SSE)Internal MicroservicesBMS Direct Commands

Enforces strict clinical protection floors (1,080 kW acute care is locked from load shedding), calculates BESS reserve countdowns, and triggers HITL governance when battery buffers drop below safety margins.

Stage 1 · Sense & Ingest

Weather + IoT Telemetry

EIS detects storm approach while edge devices stream 1s power readings & inverter efficiency logs into Maximo.

Stage 2 · Predict & Model

Granite Time Series TTM

Granite foundation model predicts 96 min ahead, projecting solar drop-off and hospital demand surge.

Stage 3 · Optimize & Stage

MMS Rules & Floor Check

MMS protects (pre-charges) the 1,500 kWh BESS to 85% and creates a 215 kW nonclinical load-shed plan; battery + Hover wind carry the 1,080 kW clinical floor if the grid fails.

Stage 4 · Authorize & Close Loop

watsonx Orchestrate + WO

Operator signs off via watsonx agent. Commands execute across BMS controllers, and Maximo dispatches maintenance WOs.
