Power supply storage capability index of smart grid and its application

摘要

In distribution network, the interconnection of distributed energy storage system (DESS) provides network with supply & storage capability which is conducive to regulate peak load and solve intermittency of intermittent energy source. DESS power supply & storage capability index is proposed to quantitatively describe the time-varied maximum power supply and storage capability of DESS, considering the effect caused by interconnection of DESS and the constraint of electrical network and DESS. The supply & storage capability index's effectiveness is verified under the context of DESS optimal economic scheduling.
