Research on the Evaluation and Optimization of Interconnection Capacity in Low-Voltage Distribution Network Based on Flexible Interconnection Devices

With the widespread integration of distributed wind power, photovoltaics, and other renewable energy sources into low-voltage distribution networks, there exists significant energy sharing potential between different zones due to the distribution disparities of loads and distributed power sources. This paper proposes a method for assessing the interconnection and energy sharing potential in low-voltage distribution zones. It analyzes the characteristics of interconnected scenarios and establishes an evaluation index system for interconnection capacity, including indicators such as wind-solar complementary capability, source-load energy sharing potential, and transformer capacity interconnection metrics. The validity of the method is verified through typical scenarios, demonstrating that the proposed approach effectively enhances the utilization of distributed energy resources and optimizes the power supply efficiency between zones.
