Universal settling model for energy communities

The emerging energy communities (ECs) create a good opportunity for more distributed generation, their integration and the enforcement of energy democracy. Nevertheless, new players, new energy flow and settlement directions also pose new challenges for the participants.In this document, we propose the system of trade and accounting methodology for energy communities.We want to lay the foundations for an accounting system that is fair to all actors and thus helps to maintain it in the long term. Simulating the quarter-hour measurements of EC members, based on real production and consumption curves, we examined their individual invoices, profits and losses based on different price and cost factor ratios.Overall, we have succeeded in establishing an accounting structure in which all actors receive the income to which they are entitled. During the simulation, the price values can be parameterized due to find the optimal proportions.
