Flexibility calculation of regional power grid based on probability analysis

A regional power grid flexibility calculation method based on probabilistic analysis is proposed. Firstly, the regulation characteristics of flexibility resources are analyzed, flexibility resource flexibility supply indexes are proposed, and the system flexibility supply capacity is calculated; secondly, the source of system flexibility demand is analyzed, and the system flexibility demand model is established to calculate the flexibility demand; finally, according to the system flexibility supply-demand equilibrium relationship, the system flexibility assessment indexes based on probabilistic statistical theory are proposed, the system flexibility is calculated, and the actual data of a certain region is collected Flexibility calculation is carried out.
