System value assessment method of energy storage system for multi‐services of power system considering battery degradation

The energy storage system (ESS) is a promising technology to address issues caused by the large-scale deployment of renewable energy. Deploying ESS business decision that requires potential revenue assessment. Current value assessment methods focus on owner or electricity utility. needs be fully considered gain broad understanding benefits across whole power system. Thus, this study proposes method grid-integrated quantify total value-avoided cost based an improved DC flow model considering transmission losses. Four typical applications (production saving, upgrade deferral, environmental benefit, and loss saving) are chosen represent In addition, co-optimisation “source-grid-storage” coordination operation battery capacity degradation, proposed for peak shaving frequency regulation Chinese market rule. tested in simulation experimental studies.
