北美电力可靠性公司（NERC）设想了一个智能电网，积极探索先进的通信网络解决方案，以促进实时监测和动态控制的大容量电力系统。在配电层面，智能电网整合了可再生能源发电和储能机制，以提高电网的可靠性。此外，动态定价和需求管理为客户提供了与电力系统互动的途径，以确定最能满足其生活方式的用电量。在传输层面，高效的通信和高度自动化的架构提供了电力系统的可见性，因此，故障的缓解速度比它们传播的速度更快。然而，这种更高水平的可靠性和效率取决于支持通信基础设施。到目前为止，公用事业公司正在转向多协议标签交换（MPLS），因为它支持流量工程和虚拟专用网络（VPN）。此外，它提供服务质量（QoS）保证和故障转移机制，除了满足NERC规定的不可路由性的要求。然而，这些好处是以支持完整MPLS规范的基础设施为代价的。通过这一实现，并在GENI中给出两周的实施和部署窗口，我们探索了低成本OpenFlow软件定义网络（SDN）解决方案所提供的模块化和灵活性。特别是，我们使用OpenFlow提供（1）自动故障转移机制，（2）负载平衡，（3）服务质量保证：智能电网网络的所有基本机制。
The North American Electric Reliability Corporation (NERC) envisions a smart grid that aggressively explores advance communication network solutions to facilitate real-time monitoring and dynamic control of the bulk electric power system. At the distribution level, the smart grid integrates renewable generation and energy storage mechanisms to improve the reliability of the grid. Furthermore, dynamic pricing and demand management provide customers an avenue to interact with the power system to determine the electricity usage that best satisfies their lifestyle. At the transmission level, efficient communication and a highly automated architecture provide visibility in the power system and as a result, faults are mitigated faster than they can propagate. However, such higher levels of reliability and efficiency rest on the supporting communication infrastructure. To date, utility companies are moving towards Multiprotocol Label Switching (MPLS) because it supports traffic engineering and virtual private networks (VPNs). Furthermore, it provides Quality of Service (QoS) guarantees and fail-over mechanisms in addition to meeting the requirement of non-routability as stipulated by NERC. However, these benefits come at a cost for the infrastructure that supports the full MPLS specification. With this realization and given a two week implementation and deployment window in GENI, we explore the modularity and flexibility provided by the low cost OpenFlow Software Defined Networking (SDN) solution. In particular, we use OpenFlow to provide (1) automatic fail-over mechanisms, (2) a load balancing, and (3) Quality of Service guarantees: all essential mechanisms for smart grid networks.
