satisfaction. However, most studies consider either EV or flexible loads individually with few researching flexible loads, energy storage, and EV collectively. Yhu and Gao [10] proposes integrated dispatch strategies considering adjustable loads – establishing a
This challenge has been exacerbated by an increased interest in the adoption of highly-uncertain electric vehicle (EV) loads as distributed energy storage (DES) devices since the owners'' attitudes and EV''s charging and discharging patterns are radically random.
In the model, the flexible loads are divided into translatable load, dispatched load and reducible load based on the energy consumption characteristics and the demand response potential. Simultaneously, the minimum comprehensive evaluation index is taken as the objective function to optimize the operation strategy and the load demand response plan …
If the flexible loads and ES cannot balance the real-time electricity deviation, consumer should purchase energy from DisCo. So the cost model for consumers is formulated as a two-stage SMIP problem.
