SIRFN Smart Grid Collaboration

Primary goal: Develop and demonstrate a consensus-based interoperability certification standard for advanced Distributed Energy Resources (DERs). Design and compare advanced interoperability test-beds.

Perform round-robin testing of advanced DER.

Compare test results, communications methods, and automation procedures.

Gradually improve draft test procedures for advanced DER with the goal of becoming an internationally-accepted standard.

SIRFN - A coordinated network of smart grid

research facilities from:

IEA (International Energy Agency)

Clean Energy Ministerial (CEM)

International Smart Grid Action Network (ISGAN)

Smart Grid International Research Facility Network (SIRFN)

Smart Grid Distribution Automation

Power Systems Testing

Advanced Laboratory Testing Methods

Test Protocols for Advanced DER Functions

Extend Test Protocols for Advanced Inverter Functions to Energy Storage Systems (ESS)

The SIRFN ESS Protocol must : • Create a concise set of test procedures for

evaluating ESS interoperability and functionality

• Consider aspects of ESS (Bi-directional, 4 quadrant capability, etc.)

• Be harmonized and inclusive with existing codes and standards

• Enable easy interpretation of test procedures by laboratory personnel

• Define test acceptance criteria

integration, EU PVSEC, Hamburg, Germany, 14-18 Sept, 2015.

Protocol Development Process

1. Review of appropriate grid codes, technical rules, standards, and ESS functions

2. Consolidation of function requirements into draft protocol language

3. Execution of draft protocol to ESS with equipment units at SIRFN laboratories

4. Updating draft protocols to improve usability and to generate better results

Protocols will be published soon for active power, fixed power factor, volt-var, and frequency-watt.

Execution of draft protocol to ESS: SIRFN Testing Laboratories

The Future of Certification Testing

Have you been struggling to complete your grid-support function testing on time?

Is your company behind schedule because of the extensive testing combinations in UL 1741 SA?

Have you grown tired of adjusting AC and DC simulator settings?

Have you found yourself repeating tests after messing up some of the tests?

Are you looking for a fast, accurate testing tool?

Then the System Validation Platform is for you!

SunSpec/Sandia System Validation Platform

Newly Released!

System Validation Platform (SVP) is an automated certification interoperability platform Fully scriptable

Interacts with DAQs, PV and grid simulators, and DER.

Power of Testing Automation

UL 1741 SA test permutations are large due to the number of settings in each advanced DER function:

75 measurements for fixed power factor - takes about 25 minutes with the SVP

375 measurements for volt/var - takes about 90 minutes with the SVP

Proposed UL 1741 SA fixed power factor tests. Proposed UL 1741 SA volt-var tests.

Conclusions

Advanced DER functions help support the electricity grid.

In the U.S., many jurisdictions are considering new DER requirements (not just CA)

Regional differences could be an issue

Autonomous functions are required first

Standardized test methods for verifying DER functionality and interoperability are critical.

Communications certification not finalized, cybersecurity a big concern

Sandia, SIRFN, and SunSpec are improving certification protocols and test capabilities by:

Building test-beds for advanced inverter testing (electrical performance and interoperability).

Comparing advanced DER test results and improving draft certification protocols.

Recommending improvements to national and international codes and standards.

CSI Project, California Context

• California is developing next-generation interconnect

rules for distributed generation (Revising CA Rule 21)

and intend to include communication capability

• But… communication technologies are diverse across

California and best choices are uncertain

• And… Inverters have decades-long service lives, and

communication technologies are evolving much faster

• And… It is uncertain when network connectivity to

residential systems will need to be deployed in

California

California Solar Initiative, Round 4 Project

Develop and demonstrate a method and

framework by which certified smart

inverters can be produced and installed

today, meeting CA Rule 21 requirements,

with assurance that they can be

successfully connected with grid

operations in the future as needed.
