Maintaining synchronism between generation and demand is becoming a tedious task with increasing penetration of renewables in the evolving power systems. Ancillary services are needed to settle these load-generation imbalances. The ancillary services requirement increasingly utilizing Energy Storage Systems (ESS) considering its quick response and high
Due to large thermal inertia of buildings and flexibility of interruptible loads, smart buildings pose a remarkable potential for developing virtual energy storage systems (VESSs). However, current literature lacks advanced models to quantify and thus properly optimize available capacity of VESS for power system ancillary services, especially frequency regulation services (FRS).
As to virtual energy storage system (VESS), Cheng et al. investigated the benefits of VESS on frequency response [17], where VESS was composed of various traditional energy storage systems (electrochemical, mechanical, electrical and thermal energy storage system) and domestic flexible loads which had ability to participate in demand response.
