Abstract Due to the increasing penetration of distributed energy resources (DERs) in the distribution network and the electricity market reform which allows demand side resources to participate in the electricity market, the leverage of flexibilities from demand-side resources has attracted more and more attentions. This paper takes electric vehicle (EV) and heating ventilating & air conditioning (HVAC) as the typical demand-side resources. Considering the physical characteristics of equipment, the behaviors of occupants and environmental factors, a generalized virtual battery model (VB) is established for characterizing the flexibilities using an extreme energy circumstance method. On this basis, a day-ahead optimal scheduling model is developed for the transactive platform to participate in the wholesale market. The numerical results show that the energy schedule and reserve capacity can be determined by the general VB model. In addition, the proposed model is verified by simulation, and its superiority in terms of computational efficiency and information security is analyzed.

Key words： Flexibilities from demand-side resources transactive platform generalized virtual battery model day-ahead optimal scheduling reserve capacity
