Benefits for Utilities
C-DAX provides multiple benefits for electric utilities:
- Secure and reliable grid operations through the secure and timely delivery of measurement data and control messages while avoiding duplicated investment in information infrastructures on a per application basis.
- Flexibility and agility to integrate emerging applications including renewable energy resources of different sizes through supporting communication with individual consumers to facilitate the growing number of active subjects connected to power grids. The penetration of emerging applications such as PEV charging and demand load management is accelerated by the plug-and-play property of C-DAX where for active subjects (including devices and applications) that are plugged into a C-DAX infrastructure, their communications and security are self-configured with no human intervention.
- Enable the addition of a resilient cyber-secure layer that addresses authentication, privacy, and integrity in an end-to-end fashion but does not require change in currently used protocols in the electric grid infrastructure. Furthermore, C-DAX will provide added value to current protocols and data models used within the power systems domain for monitoring and control purposes (e.g., IEC 61850, IEEE C37.118, etc.). C-DAX concepts will be proposed for standardization (i.e., M490, IECC T57, ETSI M2M, IETF) and other industry interest groups.
- Minimization of capital costs since C-DAX is a unified communication platform that can be used for a heterogeneous set of co-existing (current and emerging) grid applications. As such it increases the utilization of communication bandwidths compared to an approach where separate information network infrastructures are deployed per application, and thus less investments in communication infrastructure are needed.
- Minimization of operational costs since C-DAX scalable addresses management complexity and security concerns caused by the growing number of active subjects connected to electric grids (e.g., solar panels or PEVs), and furthermore allow grid applications to transparently exchange information (or sometimes store and retrieve information) irrespective of underlying communication infrastructures. Specific features enabled by CDAX are utility scale energy management, end-device authentication, bi-directional communication with energy assets, real-time remote control of energy assets, preconfigured automated response and least cost routing.
