Capability · Simulation
Physics-aware simulation across the grid edge, the building, and the district. The same simulator that runs scenario studies for planners runs as the guard for autonomous dispatch in production — the agent is constrained to actions that simulate cleanly first.
01
OpenDSS for distribution feeders and GridLAB-D for time-series studies, wrapped in a common interface. Topology imported from the customer's CIM (IEC 61968 / 61970) extracts. The simulator runs an ensemble — typically n=32 — across stochastic load and weather realizations, returning quantile bands rather than single trajectories.
02
GridSim — our open-foundations DER simulator — models VPP dispatch, BESS sizing, EV smart-charging schedules, demand response, solar siting, and microgrid islanding. Coefficients are calibrated against published research and the customer's own historical dispatch logs once enough operational data accumulates.
03
MPC-style model-predictive control models for HVAC, heat pumps, and DHW. Given a 24-48h forecast of weather and prices, the simulator schedules the building's loads to minimize energy cost while honoring comfort constraints. Documented adaptive HVAC systems in 2026 are hitting 25-35% reductions in HVAC energy and 90% reductions in peak load — without touching tenant comfort.
04
Bidirectional 5th-generation district heating + cooling networks couple thermal and electric flows. The platform models them as a coupled hydraulic-electric optimization with thermal storage, enabling demand-response coordination across both energy vectors. Reference deployments in 2026 show 14% peak-electricity shift potential through this coupling.
05
Storm-driven outage simulations with weather-conditioned failure rates per asset class. Restoration time is modeled with truck-roll dispatch + FLISR re-routing. The output is the resilience-curve operators present to regulators after a major event — except now it's a forecast, not a postmortem.
06
Before the agent commits any dispatch action, the simulator runs the proposed action against the current grid state and verifies it stays within the customer's policy envelope: voltage bounds, frequency limits, equipment ratings, comfort constraints, market-clearing rules. If it doesn't simulate cleanly, the agent doesn't act. This is the safety mechanism that lets autonomy ship.
