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).
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.
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).
The Essential Grid Operations from Solar project is a national laboratory-led research and industry engagement effort that aims to expedite the development and adoption of reliability standards for inverter-based resources.
These Specifications were established taking into account the shared goals of European grid connection network codes: to guarantee equal and non-discriminatory conditions for competition on the internal energy market, to ensure system security and to create harmonised connection terms for grid connections.
