hosting or integration capacity for renewable
resources (primarily solar PVs) across all
distribution circuits in the state, 2) compensating DERs for the energy services they provide at particular locations on the distribution
grid, and 3) building the correct electric grid
and information technology infrastructures to
enable and optimize the value of increased levels DERs.

Modern Grid, Modern
Capabilities
SCE has embarked on a plan to modernize its
grid in preparation for much higher amounts of
DERs connected to its distribution grid. SCE
presented "Modern Grid, Modern Capabilities"
at Distributech in February 2016, which defined the architecture principles for a modern
grid: "software centric designs," "standards-based
connectivity," "common semantic models," "accommodate legacy grid equipment and protocols," "end-to-end security embedded in the
architecture design," and overall "distributed
control and event-driven architectures."
This grid modernization plan recognizes the
uncertainty of future technologies, the usefulness of leveraging the significant investments
in existing systems, and the need to develop a
framework that is flexible, interoperable, and
adaptive to a fundamentally different distribution grid with predictable load and limited
resources. Figure 2 lists the capabilities envisioned to meet the needs of this evolving distribution environment.
To monitor, control, predict, and optimize the
