Multi-scenario modeling analysis of rural 10kV distribution line voltage violation based on correlation indicators

Due to the many factors that cause voltage overshoot, there are often large errors in analyzing specific out-of-limit states. For this reason, a multi-scenario modeling analysis study of rural 10kV distribution line voltage over-limit based on correlation indicators is proposed. A series of related indicators covers many aspects such as grid structure, load characteristics, equipment status, etc., to comprehensively reflect the possible reasons for voltage exceeding the limit. Combined with the distribution line model, a multi-scenario model was constructed using indicators to simulate voltage out-of-limit situations in different seasons, periods, and load levels. In this result, the occurrence probability of voltage limit violation can be accurately predicted under the background of considering access to renewable energy.
