YOSHIKAWA Daichi, a fourth-year student of the Department of Network Design, the School of Interdisciplinary Mathematical Sciences (FUKUYAMA Yoshikazu Laboratory), received the YPC (Young engineer Poster Competition) Excellent Presentation Award at the 2025 Annual Conference of Power and Energy Society, IEEJ (September 18, 2025, University of the Ryukyus). This award is given to outstanding poster presentations by participants under the age of 29.
YOSHIKAWA, FUKUYAMA, YOSHIDA, OI, JINTSUGAWA: “Selection of Optimal Voltage Measurement Points for Next-Generation Smart Meters for Power Distribution System Status Estimation,” the Annual Conference of Power and Energy Society, IEEJ, page 30, September 2025
Current smart meters (SMs) will be replaced with next-generation SMs from 2025. The next-generation SM can obtain 5-minute voltage data in addition to the measurement data obtained by the current SM and is expected to improve the accuracy of the power distribution system status estimation using this data. However, since the number of next-generation SMs for which 5-minute data can be acquired is about 3% of the total number of installations due to communication restrictions, it is necessary to select the measurement points of the next-generation SMs that maximize the accuracy of status estimation.
In this paper, YOSHIKAWA proposes a method to apply tabu search, which is a typical metaheuristic method, to the selection of voltage measurement points of multiple next-generation SMs. YOSHIKAWA confirmed the effectiveness of using the proposed method and multiple next-generation SMs by simulation for the IEEE 69 bus system.
