Value Analysis of Load Side Resource Flexibility in a New Power Load Management System Based on Value Concepts

With the gradual formation and development of a new type of power system dominated by new energy, the power grid is facing the risk of insufficient regulation capacity, and load side resources can provide flexibility for the power system at multiple time scales. Firstly, the definition of power system flexibility is introduced, and then the flexibility supply-demand balance of transmission and distribution networks at different time scales under the background of the new power system is discussed. Taking three types of load side resources with development potential, namely temperature controlled loads, electric vehicles, and load side hydrogen energy hubs, as research objects, the flexibility value and feasibility of demand side support for the flexibility demand of the new power system were analyzed.
