Prosumer Web City: a novel energy market framework for enabling dynamic bidding and scalable integration of distributed energy participants

The current smart grid technologies have a significant challenge of designing scalable, decentralized urban energy systems that fully integrate diverse distributed energy resources (DERs) with prosumer participation, dynamic pricing, and inter-web energy sharing. To address these challenges, this study presents a detailed modeling and implementation of a novel Prosumer Web City framework. The proposed framework implements a multi-web, prosumer-centric energy network integrating Photovoltaic (PV), wind, and hybrid generation sources alongside battery ES systems and dynamic pricing mechanisms. This scheme is implemented over a year for two scenarios: (i) four interconnected webs comprising twenty prosumers, and (ii) a large-scale urban deployment in New York City with 100 prosumers and 50 consumers distributed across 10 webs. Comprehensive models are developed to capture energy generation, demand, battery dynamics, grid interaction, and market-based pricing strategies. The results indicate that the hybrid webs outperform single-source webs by 15% in terms of output, 22% in terms of revenue, and 20% in terms of grid dependency. This superior performance of hybrid webs is due to the complementary nature of solar and wind energy sources. The study further identifies operational challenges related to battery capacity, transfer limitations, and consumer energy cost, and offers actionable insights for microgrid design, smart home integration, and future energy policy adapted for sustainable and resilient urban energy systems.
