Demand response is a significant means to provide flexibility for the system. First of all, a flexible load model based on the operating characteristics of electrical appliances and customer behavior is proposed, including state model, power model and probability model. This model can reasonably and accurately describe the operating characteristics of electrical appliances and the rules of customer behavior. Secondly, based on the proposed flexible load model, a flexible resource aggregation method is proposed, and a demand side flexible resource pool that can participate in permanent demand response is established. Thirdly, aiming at the limitation that the current demand response mechanism is difficult to be carried out on a large scale, a novel demand response mechanism based on customer directrix load (CDL) is proposed. CDL is not only the goal of demand response, but also the standard to evaluate the customer's contribution. Customers adjust their own power consumption under the guidance of CDL to shape the load curve. The CDL-based DR does not need to calculate the baseline for each customer, and has the potential for large-scale development. Finally, a university park in the southwest of Shanghai was tested, and the results showed that when the response capacity of the resource pool was adequate, the park could follow the target curve and fully absorb the distributed renewable energy within the park, while when the response capacity was insufficient, the park could effectively suppress the power fluctuation of its connecting lines.
