Abstract: Aiming at the difficulties in regulating energy and easily generating network loss in the traditional power dispatching process, a blockchain-based energy and power supply network scheduling optimization model is proposed. Based on the characteristics of decentralization, trustworthiness and transaction transparency of blockchain, the model of energy supply and demand network is established. Besides, the blockchain incentive mechanism is used to realize the coordinated control of distributed energy independent grid connection. Moreover, a scheduling optimization model is established based on the objective function with the lowest operating cost and the least active loss, and the collaborative co-evolutionary algorithm (CCEA) is used to solve the model. Furthermore, the energy supply and demand network is arranged through the POW consensus mechanism of the blockchain while the nodes perform distributed computing to achieve secondary verification and optimization of the scheduling scheme. The results of the example show that compared with the traditional power energy dispatching model, the proposed method can reduce the total operating cost by 9.9%, the active network loss by 3.5%, and improve the variance of daily load, which stabilizes the power system, providing decision support and theoretical support for optimizing energy and power dispatching problem.
