Electricity Cost-Sharing in Energy Communities Under Dynamic Pricing and Uncertainty

Most of the prosumers nowadays are constrained to trade only with supplier under a flat tariff or dynamic time-of-use price signals. This paper models and discusses cost-saving benefits flexible as members energy communities who can exchange electricity among peers on wholesale markets through community manager. Authors propose novel centralized post-process sharing method by introducing two-stage mechanism which, unlike existing methods, guarantees for joining community. The first stage assesses internal calculation in three different methods: Bill Sharing Method Net (BSMN), Mid-Market Rate (MMRN), Supply-Demand Ratio (SDRN). In their original form, prices calculated single comprehensive analyses show that some face increased cost. To solve this issue, improves methods second which compensation methodology is defined distribution savings ensures all gain benefits. Results investigate value inner technical flexibility prosumer (flexible preferences final consumer reduce cost from 3% up 20 %). Moreover, incentives/penalties encourage utilization behavior adjust real-time consumption prosumers’ appliances predefined day-ahead schedule. type pricing results lower amount (the reduction 18-47% MMRN 49-114% SDRN compared pricing) makes more preferable. concludes an excess PV production would not benefit BSMN due free between members.
