INTRODUCTION 1.1 Purpose The following Energy Storage System Test Manual is a series of detailed procedures developed by EPRI in concert with the Testing and Characterization Working Group of the Energy Storage Integration Council (ESIC). This manual addresses the performance and functional testing of energy storage systems (ESSs).
This manual addresses the performance and functional testing of energy storage systems (ESSs). The objective is to provide specific, detailed test procedures that are reproducible so that utilities and other testing entities can easily use them for the performance evaluation of energy storage systems . The key principles that guide this effort:
The Basic Testing and Characterization of Energy Storage Systems is intended to be storage- technology agnostic, encompassing all electricity -in, electricity -out energy storage technologies.
Integrated system tests are applied uniformly across energy storage technologies to yield performance data. Duty-cycle testing can produce data on application-specific performance of energy storage systems. This chapter reviewed a range of duty-cycle tests intended to measure performance of energy storage supplying grid services.
The goal of the stored energy test is to calculate how much energy can be supplied discharging, how much energy must be supplied recharging, and how efficient this cycle is. The test procedure applied to the DUT is as follows: Specify charge power Pcha and discharge power Pdis Preconditioning (only performed before testing starts):
