Integrated energy system distributed state estimation method based on block chain

The invention discloses an integrated energy system distributed state estimation method based on a block chain. The method comprises the following steps: establishing an integrated energy system block chain network, acquiring measured values by each energy subsystem node, constructing an integrated energy system model which comprehensively considers an energy coupling relationship, establishing an integrated energy system state estimation model, and realizing distributed state estimation and real-time control and optimized operation of the integrated energy system. The distributed architecture based on the block chain breaks the industry barriers of all energy systems in the integrated energy system, and on the premise of ensuring information credibility, a distributed solving method is combined, a large amount of measurement data in each subsystem does not need to be transmitted to a dispatching center, the information transmission amount between nodes is reduced, the state estimation speed and efficiency ar
