Award-winning paper: KOBAYASHI Yuto, FUKUYAMA Yoshikazu, SEKI Kojiro, OI Akihiro , YOSHIDA Hotaka, JINTSUGAWA Toru, FUJIMOTO Hisashi: “Study on voltage imbalance suppression method in distribution system by transposition, part 2: study on optimization of transposition point by integer-type population-based incremental learning” Joint Research Group on Systems and Smart Facilities of the Institute of Electrical Engineers of Japan, ST-22-021，SMF-22-028, 2nd November, 2022
In the distribution system of the electric power system, the introduction of solar energy generation equipment has been advanced in the general household in recent years, and the problem of the voltage imbalance between the three phase high-voltage distribution lines has become remarkable. In order to suppress this voltage imbalance, in this paper, an optimization method of the transposition point, which changes the wiring between the three phases, was investigated. The proposed method using integer-type population-based incremental learning, which is one of the evolutionary calculation methods applied to combinatorial optimization, was applied to a distribution line model using real distribution line data, and it was confirmed that imbalance can be efficiently corrected and that the calculation time can be significantly reduced by parallel processing. This research was conducted jointly with Fuji Electric Co., Ltd.
