“A low-voltage distribution station in North China has validated a three-phase imbalance management method that considers flexible load response and collaborative photovoltaic regulation. The method includes a flexible load response mode and a photovoltaic regulation mode. The flexible load response mode aims to minimize network loss and load regulation costs, while the photovoltaic regulation mode aims to minimize the number of photovoltaic phase changes. This effectively reduces the number of photovoltaic phase changes and load response regulation costs, providing a low-cost solution for three-phase imbalance management in distribution networks.”
