Efficiency evaluation algorithm of SDN for energy internet

In order to evaluate the efficiency of system communication network in energy internet, the evaluation index system should be established firstly. There is no unified standard for the efficiency evaluation index system of complex power electronics system based on Software Defined Network (SDN) now. The function of SDN in complex power electronics system is introduced in this paper and the characteristics of SDN for complex power electronics system is analyzed. According to the division of layers, the efficiency evaluation index system of complex power electronics system communication net is proposed. The meaning of evaluation index is defined and the mathematical model of evaluation index is given. The correctness of evaluation index system is analyzed from the aspects of effectiveness, reliability.
