A Stackelberg Game Strategy for Multi-microgrid Operation Considering Seasonal Hydrogen Storage

Abstract

This article proposes a master-slave game operating strategy for multi-microgrids considering seasonal hydrogen storage, aiming to solve the problems caused by the insufficient consumption of renewable energy and the seasonal imbalance of supply and demand in integrated energy systems. Firstly, this article models the seasonal hydrogen storage system and user demand response behavior, and connects multiple microgrids into a multi-microgrid system through power channels. Secondly, this article introduces a cooperative-master-slave game framework to describe the game behavior of multiple stakeholders, in which the multi-microgrid system leads energy users. After solving the master-slave game, this article uses Nash bargaining to allocate the cooperative benefits of each microgrid reasonably. Finally, through numerical examples, the strategy proposed in this article effectively promotes the consumption of renewable energy, reduces the purchasing cost of users, and promotes energy transmission among microgrids.
