Energy storage inverter testing responsibilities

Do I need a periodic test report for a smart inverter?

Periodic test reports or a log for inspection shall be maintained. The Area EPS Operator may require a commissioning test to be performed outside of the normal periodic testing to verify adherence to this standard at any time. The discussion in this section focuses on the technical requirements for verification of operation of smart inverters.

How do I complete solar capacity testing for a DC-coupled system?

For example, to complete solar capacity testing for a DC-coupled system, energy storage inverter data will likely need to be accessed and referenced. This means any network connections between the energy storage equipment and DAS should be completed prior to solar testing.

How can smart inverters improve power performance?

Dynamic Harmonics Cancellation: smart inverters could be designed to automatically adjust its settings to find an optimal voltage total harmonist (VTHD) at its terminals during steady state condition. Reactive power support during night times: future inverters could be designed to provide voltage support even when there is no input energy.

What are the applications of smart inverter technology?

Additionally, emerging applications of modern DG technologies that rely on smart inverter technology include the ability to provide ancillary services, e.g., help regulate grid voltage and frequency, and potentially support the operation of the grid during contingency conditions, including islanded microgrid operation.

How do smart inverters work?

Smart inverters may operate in either a grid forming or a grid following mode. Grid‐following is by far the most common application for smart inverters today. With increasing penetrations in many areas of the grid relevance of smart inverter PQ is heightened.

Are inverter connected der a challenge to grid power quality?

The challenge may be compared to 1980s and 90s deployment of power electronics in appliances and in process industries. This changed requirements and expectations for grid power quality. Now the grid environment is again changing because of inverter connected DER and perhaps more than ever before.
