Regional Controllers: Disaggregate central commands across geographic clusters, managing local grid constraints (distribution transformer limits, voltage boundaries, phase balance). Coordinate neighborhood-level optimization for peer-to-peer trading and microgrid formation. Update frequency: 1-60 seconds.

CORE ARCHITECTURAL COMPONENTS
Distributed Asset Aggregation Layer
The foundation of our VPP platform is a scalable asset onboarding and telemetry engine capable of integrating millions of distributed energy resources across residential, commercial, and industrial sites. We implement a hierarchical communication architecture with edge gateways for local asset clusters and cloud aggregation for portfolio-level optimization. Our multi-protocol integration framework supports diverse communication standards—Modbus, SunSpec, IEEE 2030.5, OpenADR, OCPP (EV chargers), and proprietary IoT protocols—transforming heterogeneous asset data into a unified digital twin representation. Real-time telemetry streams (power output, SOC, temperature, availability) are processed through edge computing nodes with sub-second latency, while historical data flows to centralized analytics for forecasting and optimization.
Market Participation / Bidding Engine
The bidding engine operates on a multi-market optimization framework, simultaneously participating in day-ahead energy, intraday continuous trading, balancing markets, frequency response, voltage support, and capacity auctions. Each market has distinct gate closure rules, product definitions, and qualification requirements. Our intelligent bidding algorithms construct optimal portfolios across markets, considering forecast uncertainty, opportunity costs, and asset technical constraints. For day-ahead markets, stochastic optimization determines energy positions accounting for renewable variability. For balancing markets, real-time capability assessment ensures bid fulfillment. For ancillary services (FCR, aFRR, mFRR), dynamic reserve allocation balances revenue opportunities against energy market positions. The system automatically handles pre-qualification documentation, capability testing, baseline submissions, and settlement reconciliation across all markets.
Flexibility Forecasting & Baseline Engine
Our forecasting engine predicts both generation potential and flexible capacity across the entire DER portfolio. Advanced machine learning models combine weather forecasts, historical consumption patterns, occupancy predictions, and behavioral analytics to establish baseline consumption and quantify available flexibility. For solar assets, site-specific irradiance forecasting accounts for rooftop orientation, shading, and panel degradation. For batteries, state-of-charge tracking and degradation modeling ensure longevity-optimized dispatch. For flexible loads (HVAC, industrial processes, heat pumps), thermal models predict comfort constraints and operational boundaries. For EV fleets, mobility pattern recognition forecasts vehicle availability and charging flexibility. Ensemble prediction intervals provide uncertainty quantification critical for reliable market participation and imbalance risk management.
