Application of the multiagent approach to the research of integrated energy supply systems

Abstract

The current technological infrastructure in the electricity, heat, cold, and gas supply, as a rule, is formed and controlled separately by local systems and tasks. The traditionally considered energy systems unite large energy sources, such as hydroelectric power station, combined heat and power plants, boiler plants, and electric and pipeline networks distributed over a large area. New trends in the energy sector necessitate a revision of the principles of construction of energy systems and the creation of integrated energy supply systems. Combining separate different types of systems of different levels into a single integrated system with many coordinated elements can contribute to the implementation of new functionality, the use of more advanced technologies in operation and the active participation of consumers with distributed generation in the energy supply process. For the study of integrated energy supply systems it is proposed to use a multiagent approach, which is one of the promising areas of research for complex systems. This approach is used in many subject areas to study systems that include many elements with complex behavior. Such systems include integrated energy supply systems. The solution of the problem on the basis of the agent approach is developed by a multitude of interrelated agents.

Research of A Multiagent Model of An Integrated Energy Supply System Developed in the Anylogic Software Environment

“…Based on the structure of a multiagent integrated energy supply system described in [10], its model was developed in the AnyLogic software environment. The basis of this model is the interaction of agents of two systems (electrical and heating) in order to study the mechanisms of functioning of agents and their coordination.…”

“…In the second case, if the power line cannot miss the specified power, the power line agent goes into a failure state and sends a message to the agent network with the "Refusal" parameter (10). After that, the power line agent is waiting a response from the power station agent associated with it.…”

“…6). And it sends a message to the agent network with the "Refusal" parameter (9), and then goes back to the waiting state of requests (10). At the same time, the consumer is not supplied from this power station.…”

“…The model developed on its basis allows one to study the mechanisms of functioning and interaction of agents [6][7][8][9]. The principles of building integrated systems and the features of applying the multiagent approach for their study were considered previously [10]. This article presents a multiagent model of an integrated energy supply system developed in the AnyLogic software environment, and also describes an experiment with this model.…”
