Model of interaction of prosumers in an integrated energy system in cooperation

Distributed generation technologies, including renewable energy sources such as solar, wind, and com-bined heat and power (CHP) systems, are currently being developed to support the transition to carbon-free energy. The development of distributed energy sources leads to the spread of prosumers who can both produce and consume energy. Thus, due to the increasingly complex interaction conditions in modern energy supply systems, such as conflicts of interests and incomplete information about the state of the entire system among all participants in the energy supply process, new modeling methods are being actively developed, including those using game theory approaches. The paper presents a mathematical formulation of the problem of optimal interaction between a centralized system and prosumers in an integrated energy system. A model is proposed that implements the interaction between centralized and distributed energy sources when prosumers are united in cooperation within a multilevel integrated energy system. A multi-agent system implementing the proposed model has been developed, on which computational experiments have been carried out on a test circuit of an integrated energy system. The obtained experimental results demonstrate the possibilities of ensuring optimal interaction between participants in the energy supply process in an integrated energy system, taking into account their interests when forming coalitions of prosumers.
