Enabling Utility Use-cases Through a Hybrid Advanced Communication Network Consisting of Fiber Optics and PLTE

As ComEd continues to invest in its grid modernization efforts, a hybrid advanced communication network model consisting of both fiber optics and PLTE can help to enable utility use-cases such as Advanced Distribution Protection using IEC 61850 GOOSE, DERMS, Lateral protection, enhanced monitoring/control, event analysis, next generation SCADA, etc. ComEd recognizes the need to provide a low latency, high bandwidth network to achieve many of the clean energy goals enabled by grid modernization programs. Initial network designs focused on fiber optics which led to developments such as ComEd’s patented EDRP (Expedited, Deterministic, Redundant, PON) resulting in a robust and deterministic network that provides fast-failover redundancy to end devices. Fiber is the foundation for ComEd’s advanced communication network. The design of a hybrid wireless and wired network enables efficiencies in deployment that can support more benefits than a wired deployment alone. When a primary or redundant fiber path is not feasible due to cost, real-estate limitations, etc., PLTE is an option to extend the network in what is commonly known as the “last mile” of the network to reach end-devices.
