IEC/TR 61850-90-7:2013(E) describes the functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter.

The U.S. Department of Energy’s Energy Storage Systems (ESS) Program, through the support of Pacific Northwest National Laboratory (PNNL) and Sandia National Laboratories (SNL), facilitated the development of the protocol provided in this report. The focus of the protocol is to provide a uniform way of measuring, quantifying, and reporting the performance of ESSs in various applications; something that does not exist today and, as such, is hampering the consideration and use of this technology in the market.

This report supplements the report, "Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems," PNNL-22010, Rev. 1, June 2014. It provides the background and documentation associated with the determination of a duty cycle to be applied to an energy storage system (ESS) in a microgrid operated in an islanded mode, for the purpose of measuring and expressing ESS performance in accordance with the June 2014 protocol for measuring and expressing ESS performance.
