Plain-Language Brief

The authors propose SolarChain-Eval, a benchmark for evaluating the trustworthiness of autonomous agents in decentralized energy markets. It assesses market utility, physical safety, slippage, action smoothness, spatial fairness, and auditability, using a Gymnasium-compatible Markov Decision Process. The benchmark includes an LLM-based Planner/Auditor layer for agentic evaluation.

What the Document Says

  • The text introduces SolarChain-Eval, a benchmark for evaluating trustworthy economic agents in decentralized energy markets.
  • It uses a Gymnasium-compatible Markov Decision Process to formulate market governance as an hourly decision-making process.
  • SolarChain-Eval evaluates policies across multiple dimensions including market utility, physical safety, slippage, action smoothness, spatial fairness, and auditability.
  • It includes an LLM-based Planner/Auditor layer to support agentic evaluation, with the Planner defining episode-level action bounds and audit rules, and the Auditor reviewing and revising high-risk actions.
  • The text mentions experiments with various policies (static, random, myopic, RL, RL+LLM) revealing a utility-safety trade-off.
  • RL agents improve market utility but can still produce unsafe behavior. When the physics penalty is removed, reward-maximizing agents exploit invalid generation and increase artificial liquidity.
  • The LLM Planner/Auditor improves auditability and mitigates selected risks, but it cannot fully compensate for a misspecified reward function.
  • The authors release data and code as open access on GitHub for replicability.

Raw Abstract / Excerpt

As agentic AI systems are increasingly applied to cyber-physical environments, their evaluation requires assessment of both task performance and trustworthiness. In decentralized energy markets, autonomous agents may improve market utility, but may also exploit invalid physical data, create artificial liquidity, and produce unstable governance decisions. Therefore, we propose SolarChain-Eval, a physics-constrained benchmark for evaluating trustworthy economic agents. It formulates market governance as a Gymnasium-compatible Markov Decision Process, where agents make hourly decisions. SolarChain-Eval evaluates each policy across multiple dimensions, including market utility, physical safety, slippage, action smoothness, spatial fairness, and auditability. To support agentic evaluation, SolarChain-Eval incorporates an LLM-based Planner/Auditor layer. The Planner defines episode-level action bounds and audit rules, while the Auditor reviews and revises high-risk actions. All interventions are recorded through structured logs, including trigger signals, proposed actions, revised actions, and audit rationales. Experiments with static, random, myopic, RL, and RL+LLM policies reveal a clear utility-safety trade-off. RL agents improve market utility but can still produce unsafe behavior. When the physics penalty is removed, reward-maximizing agents exploit invalid generation and increase artificial liquidity. The LLM Planner/Auditor improves auditability and mitigates selected risks, but it cannot fully compensate for a misspecified reward function. These results indicate that trustworthy agentic AI evaluation requires both physical constraints and transparent intervention traces. We release data and code as open access on GitHub for replicability.
