Credit Rating-Based Transactive Energy System With Uncertainties in Energy Behavior

In recent years, the evolution of demand-side management techniques has ushered in substantial improvements for distribution systems. Among these advancements, the Transactive Energy System (TES) emerges as a promising innovation, empowering end-users by facilitating surplus generation/demand trading within local energy markets. However, in contrast to the wholesale electricity markets of conventional grids, TES integrates a significant share of small-scale prosumers and highly variable intermittent Distributed Energy Resources (DERs), introducing elevated market uncertainties. In this conditions the economic stability of TES hinges on active and credible participant engagement. The central challenge lies in addressing uncertainties surrounding the energy requirements of community participants and incentivizing their involvement. To address these challenges, this paper introduces a novel market clearing strategy based on credit ratings. This strategy aims to mitigate uncertainties while motivating credible participants through substantial savings on their electricity bills. Further this paper presents final demand response consideration, among a group of participants in a TES using an auction-theoretic approach which increases monetary gains. The effectiveness of this proposed methodology is validated through comprehensive case studies involving multiple households within a community. The results are highly promising, with participating households realizing monthly savings of 17.18%, 16.11%, 20.7%, and 23.22% on their electricity bills when compared to the latest transactive energy exchange method. These tangible outcomes underscore the significant positive impact achievable through the implementation of our proposed market clearing approach and demonstrate the substantial increase in monthly savings for participants across various scenarios.
