To investigate the impact of renewable energy uncertainties on distribution networks and explore the application of blockchain technology in optimizing distribution network dispatch, this study delves into the development of renewable energy and its application in the energy sector. Additionally, it analyzes the effects of renewable energy uncertainties and integration on distribution networks. The study emphasizes the growing importance of renewable energy in the global energy landscape, particularly the potential impacts of uncertainties in solar and wind energy on the stability and efficiency of distribution networks. Furthermore, this study examines the structure of distribution networks and explores optimization strategies based on blockchain technology, optimizing distribution network dispatch through experiments with proposed strategies. Experimental results indicate that with increasing data volume, the proposed optimization model enhances system stability, decreasing from 0.98 to 0.95, significantly better than the stability of traditional models at 0.88. In terms of operational costs, the proposed optimization model performs better, increasing from 4700 yuan to 5600 yuan, compared to 6500 yuan for traditional models. In terms of automation levels, the proposed optimization model increases from 0.8 to 0.84, while traditional models decrease to 0.64. Regarding system response time, the optimization model maintains a range of 3.0 to 3.3 seconds, superior to the 5.5 seconds of traditional models. These data demonstrate significant advantages of the proposed optimization model in distribution network optimization, particularly in handling large data volumes. Thus, this study holds implications for optimizing and scheduling distribution networks. However, there are limitations to this study. Firstly, the experimental simulations are based on theoretical models, which may differ in complexity from actual power grid systems. Secondly, the practical deployment and application of blockchain technology may face challenges in technology, cost, and regulatory aspects. Future study could focus on experimental validation in actual distribution network systems, further exploring the effectiveness of blockchain technology in different grid environments and assessing its economic feasibility. Additionally, integrating blockchain technology with other emerging technologies is a crucial direction for future research.
