Modeling of Flexible Resource Willing to Response Based on Utility Theory: A Case Study of Thermal Load

With the increasing penetration of renewable energy, the flexibility of the generation side tends to reduction, which further reduces the renewable energy consumption capacity of the grid. Deeply mine the potential of some demand side resources has become an effective way to improve the flexibility of power system. This paper proposes a modeling method of flexible willingness to response based on bilateral perceived utility. First, the power data of load is used to deeply mine the electricity consumption behavior of consumers, and the load's power utility is quantified from the aspects of user's economic efficiency and electricity consumption behavior. Then, from the grid side, the flexibility utility of the power grid is quantified based on renewable energy consumption and economic efficiency. Finally, thermal load is taken as a typical case to proves the effectiveness of the bilateral utility model in describing the response willingness of flexible resources to renewable energy consumption.
