Determination of Duty Cycle for Energy Storage Systems Integrated with Microgrids
Purpose: 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.

Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems
Purpose: The "Protocol for Uniformly Measuring and Expressing the Performance of Energy Storage Systems" (PNNL-22010) was first issued in November 2012 as a first step toward providing a foundational basis for developing an initial standard for the uniform measurement and expression of energy storage system (ESS) performance. Its subsequent use in the field and review by the protocol working group and most importantly the users' subgroup and the thermal subgroup has led to the fundamental modifications reflected in this update of the 2012 Protocol.
