A Software Defined Networking Architecture for DDoS-Attack in the Storage of Multimicrogrids

Multi-microgrid systems can improve the resiliency and reliability of power system network. Secure communication for multi-microgrid operation is a crucial issue that needs to be investigated. This paper proposes multi-controller software defined networking (SDN) architecture based on fog servers in multi-microgrids electricity grid security, monitoring controlling. The proposed defines support vector machine (SVM) detect distributed denial service (DDoS) attack storage microgrids. information local SDN controllers managed supervised by master controller placed application plane properly. Based results detection, scheduling problem solved send command change status tie sectionalize switches. optimization cloud server implements modified imperialist competitive algorithm (MICA) solve this stochastic mixed-integer nonlinear problem. effective performance approach using an SDN-based evaluated through applying it IEEE 33-bus radial distribution with three microgrids simulation results.
