A General Approach to Modeling Demand-Side Resources

Due to the increasing penetration of distributed energy in the distribution network and the opening of the electricity selling side in the power reform, it becomes more and more important to give full play to the flexibility of the demand side resources. Taking typical demand-side resources such as electric vehicles (EV), air conditioners (AC) a as examples, this paper takes into account the physical characteristics of the equipment and the influence of human and environmental factors, and uses the extreme energy scenario method to establish a universal virtual battery (VB) model to describe the flexibility of its resources. A set of standard parameters is used to quantify its schedulability flexibility. These resources optimize their own electricity consumption plan according to the change of TOU electricity price, reduce the electricity cost, and achieve the function of peak clipping and valley filling. At the same time, it hides the specific electricity consumption information of consumers, which protects the commercial privacy of users in the process of participating in the electricity market transaction and the operation of the power system to a certain extent.
