Zusammenfassung:Provided in the embodiments of the present disclosure are a hybrid state estimation method and apparatus for an integrated energy system. The method comprises: performing state estimation on each node in an integrated energy system according to measurement data of the integrated energy system and in conjunction with a pre-constructed coupling device model, so as to obtain a first state estimation result; performing state estimation on each node in the integrated energy system on the basis of the measurement data of the integrated energy system and a pre-constructed distributed state estimation model, so as to obtain a second state estimation result; and performing merging processing on the first state estimation result and the second state estimation result, so as to obtain a state estimation result of the integrated energy system. In the present application, hybrid state estimation is performed by means of performing state estimation on an integrated energy system on the basis of a coupling device model and
