Designing Test Methods for IT-Enabled Energy Storage System to Evaluate Energy Dynamics

With increasing interests in renewables, more consumers are installing an energy storage system (ESS) intheir backyards, and thus, the ESS will play a critical role in the emerging smart grid. Due to mechanicalproperties, however its operational dynamics must be well understood before connecting the ESS to the smartgrid (and eventually to an IT system). To this end, we investigate charging and discharging processes in detail. This paper, then, proposes methods for four type tests (state of charge test, conversion efficiency test,response time test, and ramp rate test) that can assess the dynamics of the ESS. The proposed methods cancapture accurate delay values of mechanical processes in the ESS, and it is expected for those values to helpdesign real-time communication systems in the smart grid involving the ESS.
