Conversational Demand Response: Bidirectional Aggregator-Prosumer Coordination through Agentic AI
This paper introduces Conversational Demand Response (CDR), leveraging agentic AI to enable bidirectional natural language coordination between aggregators and prosumers. Addressing the limitations of traditional DR—low participation, lack of transparency, and one-way communication—CDR integrates LLM-based aggregator and HEMS agents. The HEMS uses an optimization tool to assess flexibility and present clear cost-benefit analyses, fostering informed prosumer decisions and sustained engagement. Proof-of-concept evaluations show interactions complete in under 12 seconds, demonstrating CDR's potential for scalable, transparent, and user-centric demand response.

The Challenge in Demand Response
Residential demand response (DR) faces significant challenges, including low voluntary opt-in rates (rarely exceeding 20%), lack of transparency, and perceived loss of control by prosumers. Existing coordination mechanisms are either fully automated (undermining user agency) or rely on static, one-way dispatch signals, offering little room for informed decision-making or real-time adaptation. This leads to unsustainable participation and limits the realization of crucial load flexibility.
Introducing Conversational Demand Response (CDR)
Conversational Demand Response (CDR) addresses these limitations by establishing a bidirectional, natural language coordination mechanism between aggregators and prosumers, powered by agentic AI. It uses Large Language Models (LLMs) as autonomous, tool-using agents capable of planning, reasoning, and interacting with external tools. CDR aims to provide the scalability of automation while preserving the transparency, explainability, and user agency vital for sustained prosumer participation.
Two-Tier Multi-Agent Architecture
CDR employs a two-tier multi-agent system. An 'Aggregator Agent' manages the portfolio, identifies flexibility opportunities from market signals, and dispatches contextualized DR requests. A 'Prosumer HEMS Agent' (Home Energy Management System) receives these requests, delegates feasibility assessment to specialized sub-agents (e.g., a 'Battery Optimizer' using MILP), and translates technical results into natural language options for the prosumer. This hierarchical structure ensures domain-specific assessment while maintaining conversational coordination.
Enhanced Capabilities with CDR
CDR enables several key capabilities: Real-time Coordination (aggregator adapts requests to prosumer context), Portfolio Planning (upcoming events communicated to prosumers), Performance Feedback (quantified impact/earnings), Transparent Participation (prosumers see full impact before committing), Explainable Compensation (rewards linked to market conditions), and Adaptive Preference Setting (prosumers update constraints anytime). These features collectively enhance user agency and trust.
Feasibility & Performance
The proof-of-concept evaluation demonstrates that CDR interactions complete rapidly, typically under 12 seconds for downstream (aggregator-initiated) scenarios and 1-2 seconds for upstream (prosumer-initiated) scenarios. Downstream interactions involve 3-5 reasoning iterations and 2-4 tool calls. The system consistently produces outputs across repeated runs, confirming its ability to sustain conversational interaction speeds necessary for real-time transparency and prosumer engagement in operational DR timescales.

| Feature | Conventional DR | Conversational DR (CDR) |
|---|---|---|
| Transparency | Low (static signals, opaque) | High (NL explanations, clear trade-offs) |
| User Agency | Limited (comply/opt-out) | High (informed decisions, bidirectional control) |
| Adaptability | Low (static requests, no real-time context) | High (real-time context, preference updates, dynamic requests) |
| Communication | Unidirectional (aggregator to prosumer) | Bidirectional (aggregator ↔ prosumer NL dialogue) |
| Prosumer Engagement | Low (behavioral barriers, trust issues) | High (trust, explainability, performance feedback) |
Aggregator-Initiated DR Dispatch Scenario
In a proof-of-concept scenario, the aggregator requested 3 kW of flexibility for a 2-hour evening window (17:00-19:00). The aggregator agent identified the most suitable household (HH-001) and dispatched the request. The HEMS agent, using its battery sub-agent and MILP optimizer, confirmed full feasibility without comfort impact and calculated a net benefit of €1.13. Upon prosumer approval, the HEMS submitted the commitment, and the aggregator updated its portfolio, completing the interaction in less than 10 seconds. This demonstrates the seamless, transparent, and user-empowering execution of a DR event via CDR.

Your Implementation Roadmap
A strategic path to integrating agentic AI for advanced demand response in your operations.
Phase 1: Foundation & Agent Setup
Establish core LLM agents for aggregator and HEMS, integrate basic communication protocols, and set up initial market signal parsing capabilities. Focus on robust natural language understanding for initial requests.
Phase 2: Bidirectional Communication Rollout
Implement the full bidirectional natural language flow. Develop simple scheduling and feasibility assessment for discrete loads. Enable prosumer-initiated upstream communication for basic preference updates.
Phase 3: Advanced Optimization & User Experience
Integrate MILP-based optimizers for complex assets like batteries, allowing for cost-optimal charge/discharge scheduling. Refine natural language explanations for feasibility, cost-benefit, and comfort impact. Enhance the prosumer interface for dynamic preference setting.
Phase 4: Pilot & Feedback Loop
Conduct a small-scale pilot with a select group of prosumers to test the system in a real-world environment. Gather user feedback on transparency, agency, and ease of use. Iterate on agent prompts and coordination logic to improve performance and user satisfaction.
Phase 5: Scalable Deployment & Portfolio Management
Expand the CDR system to a larger prosumer base, optimizing for multi-household coordination and portfolio management for the aggregator. Explore integration with higher grid layers (e.g., DSO-TSO) and advanced data privacy solutions for wider adoption.
