Distributed energy storage vehicle after-sales service

Why are distributed energy resources and EV charging important?

Distributed energy resources (DER) and electric vehicle (EV) charging that provide grid services will increasingly be important to manage local distribution needs affordably.

How are distributed energy resources changing the electric sector?

Higher penetration of distributed energy resources (“DERs”), including customer-sited solar photovoltaic (“PV”) systems, electricity storage, and electric vehicles, is changing the way we plan and operate the electric distribution system. The requirements and expectations for the electric sector are also undergoing significant change.

What is a managed EV charging and battery storage program?

A managed EV charging and battery storage program or DER aggregation could address the distribution issue and mitigate net demand variability at the bulk power system. This would reduce the demand variability and associated need for bulk power system flexibility services.

Why do distributed solar and consumer EV charging systems have operational variability?

In addition to the distribution challenges described above, distributed solar and consumer EV charging introduce operational variability into the bulk power system primarily due to their inherent characteristics of intermittency and unpredictability that impact both supply and demand dynamics.

What is a three-stage evolutionary model for electric distribution systems?

Underlying this discussion is a three-stage evolutionary model for U.S. electric distribution systems to enable DER and their evolving use as aggregated DER, or virtual power plants (VPP), for a broad range of grid and energy services (Figure 2).

How can a distribution system improve electric vehicle charging?

The above-mentioned literature also proposes some solutions regarding the potential impacts present in the distribution system while charging electric vehicles. For example; intelligent load management approaches, managed charging strategies to restrict voltage and power to enhance the penetration of BEVs, and automatic system voltage controllers.
