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 electn'cal network and DESS. The supply & storage capability index's effectiveness is verified under the context of DESS optimal economic scheduling.%W artykule przedstawiono zagadnienie oceny zdolno?ci wytwarzania i gromadzenia energii elektrycznej w systemach typu DES (ang. Distributed Energy Storage). W tym celu zaproponowano indeks, okre?laj?cy wielko?ci maksymalne wymienionych czynników, uwzgl?dniaj?cy mo?liwo?? ??czenia DES mi?dzy sob? i z sieci?. Opisano sposób weryfikacji otrzymanego parametru.
