Architecture of Value Creation
Four clean layers. One coherent DER integration thesis.
IEEE 2030.5 + IEC 61968
Strict Pydantic v2 validation and mapping to Common Information Model (CIM). Converts raw vendor telemetry into standardized, queryable DERDevice and DERTelemetry records ready for any grid application.
FastAPI + InfluxDB + PyTorch
High-performance async REST API, time-series storage (InfluxDB with SQLite fallback), and the lightweight PyTorch LSTM engine for real-time forecasting, anomaly detection, and control recommendation.
Audit + Metrics + Grafana
End-to-end structured logging, Prometheus exposition, Grafana monitoring dashboards, and bidirectional control command routing back to physical DER hardware. 100% request traceability by design.
Request & Control Flow (Simplified)
DER Hardware (Inverter / BESS / EV) → Protocol Adapters → CIM Normalizer & Validation → InfluxDB + Digital Twin → REST API → SCADA / VPP / DERMS.
Forecasts and control commands flow back through the same deterministic path. Every step is logged, validated, and standards-aligned. No magic. Just reliable grid infrastructure.
