Coordinated Energy Management Systems for Multi-Energy Negotiated Transaction with Marginal Cost Information and Its Properties from the Viewpoint of Graph Complexity

Multi-energy networks, which include electricity, heat, and fuel energies, have attracted attention in recent times. These energies should be traded in market dynamics to maximize total economic benefits. However, energy transmission constraints caused by heat and/or fuel network structure restrict trading with market transactions. Therefore, in this paper, a coordinated energy management system based on negotiated transaction mechanism is considered. Then, a transaction protocol based on marginal cost of energy accommodation is proposed. Some properties of a general multi-energy network of negotiated transactions are also discussed. Then, the spatiotemporal multi-energy network is proposed as a generalized energy transformation model, along with an investigation of its properties from the viewpoint of graph complexity with a simulation example.
