Abstract:

In view of the low efficiency of new energy utilization, slow information transmission, and poor network security in the current distribution network system, a blockchain-based future distribution network optimization planning model is proposed. Combining the characteristics of blockchain decentralization and information traceability, a blockchain-based future distribution network architecture is built. Considering the high penetration rate of renewable energy within the future distribution network, the multi-scenario analysis method is used to complete the design of the distribution network optimization planning model in multi-scenarios, which effectively solves the volatility problem caused by distributed power generation. The improved ant colony algorithm is adopted to dynamically process the pheromone heuristic factor and the expected heuristic factor to improve the global search capability of the algorithm. Based on this, by drawing on the advantages of distributed computing algorithms, the PoW consensus mechanism is combined with the idea of the distributed algorithm, which greatly improves the efficiency of the planning model solution and verification process. The analysis results of the calculation examples show that the proposed blockchain-based future distribution network optimization planning model can not only improve the utilization rate of new energy, but also ensure the safety and efficiency of the distribution network system.
