A Methodology for Optimal Dispatching of Honeycomb Distribution Network Considering System Reliability

With the growth and penetration of distributed renewable energies, the limitations of the distribution network with traditional topology are gradually manifested. The uncertainties from renewable energies and the diverse needs of electricity consumers bring additional challenges to the distribution network and its operators. A novel honeycomb distribution network (HDN) topology, together with its key device smart power/information exchange station (SPIES), is introduced in this paper to improve the traditional distribution network in terms of the integration of renewable energies. The features and advantages of HDN are firstly introduced followed by the mathematical models of main devices. Then a multi-objective two-level optimization dispatching model of HDN considering system reliability is proposed and then solved. Through a numerical simulation, the feasibility of proposed optimization dispatching model is verified and the functions of SPIES are presented. The results of this paper also reveal some advantages of HDN for the future distribution network with renewable energies.
