Analyzing Value-Sharing Methods in Energy Communities with Coalitional Game Theory

Within energy systems, collaboration has recently gained increased attention from academia and industry. However, the success of collaboration requires a fair value-sharing method based on the individual contributions. Coalitional Game Theory (CGT) offers a conceptual framework for analyzing projects where participants cooperate or collaborate to achieve favorable outcomes. The growing importance of collaboration in Energy Communities (ECs) suggests the development of CGT-based frameworks designed to understand the behavior and relationships among diverse players in a variety of operational and planning contexts. This work presents an overview of recent developments in CGT and their application in ECs, starting with a concise theoretical explanation of CGT, focusing value-sharing methods. It then examines recent applications of CGT in addressing operational and planning challenges within ECs. The paper concludes with a brief discussion on limitations, opportunities, and potential paths for further research in this field.
