Energy storage inverter industry standards and specifications

What standards are required for energy storage devices?

Coordinated, consistent, interconnection standards, communication standards, and implementation guidelines are required for energy storage devices (ES), power electronics connected distributed energy resources (DER), hybrid generation-storage systems (ES-DER), and plug-in electric vehicles (PEV).

Does industry need energy storage standards?

As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards …” [1, p. 30].

What are electrical interconnection guidelines & standards?

Electrical interconnection guidelines and standards for energy storage, hybrid generation-storage, and other power electronics-based ES-DER equipment need to be developed along with the ES-DER object models for power system operational requirements.

Can tripping a high level of inverter based systems cause stability problems?

As low frequency is the result of insufficient generation, tripping a high level of inverter based systems would contribute to the problem and cause possible stability issues in response to a relatively minor disturbance. Appropriate interconnection standards, smart grid devices, and storage are all key elements of the solution.

What are the different storage requirements for grid services?

Examples of the different storage requirements for grid services include: Ancillary Services – including load following, operational reserve, frequency regulation, and 15 minutes fast response. Relieving congestion and constraints: short-duration (power application, stability) and long-duration (energy application, relieve thermal loading).

Are energy storage codes & standards needed?

Discussions with industry professionals indicate a significant need for standards …” [1, p. 30]. Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps.
