Flexibility Resources Aggregation and Disaggregation Method Considering Renewable Consumption

As the pressure of new energy consumption increases, load side resources serve as economic regulation resources to provide flexible regulation capabilities for the power grid. To reduce the scheduling, computing, and management burden of ubiquitous access of distributed resources, the load side resource aggregation provide an interface for grid collaborative scheduling. By using the aggregation equivalence method based on the zonotope to characterize the time-varying scheduling parameters of resources, an aggregation method is proposed to construct an approximate objective function considering the demand of new energy consumption inside and outside the cluster. The aggregation loss is divided into periods with lower demand for new energy consumption, thereby improving the effective accuracy of the aggregation method. In the disaggregation process, design new energy consumption factors to maximize the consumption of new energy within cluster. Finally, through practical example verification, the aggregation efficiency of clusters covering multiple types of resources such as source, load, and storage was verified. The results showed that the improved aggregation and disaggregation methods effectively improved the regulatory efficiency of load side resource participation in assisting new energy consumption.
