Benefits of Software Defined Networking for Smart Grid Applications

Software Defined Networking (SDN) has been called the next revolution in the networking industry. It has the capability of coupling the applications tightly together with the network and offers a better way to manage networks, automate services and build applications. It gives network operators more control of their infrastructure and makes customization and optimization easier. Particularly, SDN technology enables the network to be more controllable, scalable, programmable, securable and adaptable. These characteristics are also highly desirable features for dynamic Smart Grid applications. It is believed that the incorporation of SDN into Smart Grid applications will dramatically improve Grid operation. This paper discusses the benefits of using SDN technology in Smart Grid operation in the scenarios of: power outage management and self healing capability, demand response (DR) service and distributed green energy management and dispatch. These three areas are important drivers for Smart Grid deployment. With the help of SDN technology, the utilities will be able to mitigate faults and restore service faster and more efficiently. This reduces equipment damage and cascading power failures. SDN technology is also able to provide the flexibility in supporting a multi-tier, a more complex, more dynamic and more customized and optimized DR program based on region-specific load features, special needs, preferences and security requirements. In addition, SDN solutions will help address the challenges that face distributed green energy sources management and dispatch.
