Abstract: The software defined networking (SDN) enabled architecture is becoming an effective communication method for smart grids. To achieve load balancing and fast recovery in smart grids in case of failures, the services are firstly divided into different levels according to requirements of service latency, bandwidth and impact on the smart grid operation. Then, a mathematical model is formulated for maximizing of the link availability with the constraints of service requirements and substation level difference. Thirdly, the service rerouting algorithm for load balancing (SRALB) is exploited to solve it. Finally, this scheme is verified in IEEE14 system, and it is demonstrated that the proposed algorithm not only guarantees better performance for services but also has lower standard deviation and substation level difference than the existing algorithms.

Key words: rerouting, link availability, substation level, load balancing
