Optimal Planning Method of Generation-Load-Storage Considering Multiple Types of Flexibility Resources in New Power System

To achieve carbon peaking and carbon neutrality goals, power system is facing the stability challenges posed by the large-scale integration of renewable energy. It is necessary to build a certain scale of flexibility resources by means of co-planning in order to adapt to the enormous growth of renewable energy installations. Firstly, the principles of three types of flexibility resources in new power system is described in the paper, and a mathematical model is proposed to describe the regulation process of the flexibility resources. Secondly, a new power system generation-load-storage co-planning model considering multiple types of flexibility resources is constructed. Finally, this model is combined with a long-term time-series production simulation model to verify the feasibility of the planning results.
