Evaluating the Impact of Connectivity on Transactive Energy in Smart Grid

In future power systems, local energy networks (LENs) as one of the main infrastructures will have a key role in the realization of transactive energy (TE) exchange between involved players. In order to adopt this environment fully accessible to trade energy competitively between participants, the connectivity level of the network should be always retained. The connectivity is an attribute of the LENs which determines local network transitive capability (LNTC). This letter investigates the ways to widely implement the TE framework using the connectivity strength among prosumers, customers, and local networks. A methodology to derive the connectivity index for LENs is proposed based on the graph theory and algebraic approach in this letter. The proposed method could be considered as a supporting tool for TE management in future power systems. It is found that the strength of connectivity between the participants has direct influence on the quantity as well as quality of their energy transactions. It is considered that
