Abstract: As renewable energy sources (RES) continue to rise, local energy markets (LEMs) play an increasingly vital role in enhancing system efficiency. This study introduces a comprehensive framework for assessing demand response programs (DRPs) in hybrid LEMs, where peers can trade across community-based and peer-to-peer markets, as well as the grid. To this aim, a novel bi-level optimization model is developed to minimize energy-sharing costs and maximize peer welfare by evaluating consumer and prosumer behaviors. The model considers dynamic temporal demand flexibility, enabling self- and cross-time interval adjustments over a 24-h period, allowing demand to shift, increase, or decrease in response to DRP price signals and influenced by customer risk preferences, hybrid market dynamics, and renewable energy availability. A Quality of Experience fairness index is introduced to evaluate the equity of energy distribution among consumers within the proposed market framework. A decentralized solution approach is proposed to facilitate participant negotiations, reflect individual preferences, address interactions between LEM and DRP pricing, and overcome challenges such as data aggregation, privacy concerns, and communication constraints, thereby eliminating the need for centralized optimization. The model's feasibility is validated through extensive simulations using real-time load and market price data from the Japan Electric Power Exchange in Tokyo. Results demonstrate rapid convergence, high scalability, and improved fairness. Furthermore, the availability of local RES decreases demand sensitivity to DRPs, with responsiveness, load factor, energy savings, and peak demand reduction shaped by the level of local generation and individual risk preferences. These results highlight the model's effectiveness in improving grid efficiency and maximizing benefits for participants.
