Against the backdrop of the "dual carbon" goals, green shipyards are in urgent need of optimizing energy efficiency and achieving green transformation through new energy and intelligent technologies. The practice of electrical automation management for PV (photovoltaic)-energy storage-load microgrids aims to explore a path for shipyards to realize clean energy utilization and dynamic load regulation under complex operating conditions. By enabling the efficient integration of PV systems, intelligent dispatching of energy storage systems, and optimized control on the load side, a stable, safe, and low-carbon microgrid operation mode has been established. This mode not only improves the shipyards' energy self-sufficiency rate and power quality but also effectively reduces the cost pressure caused by peak-valley differences. This study emphasizes the key role of the electrical automation management platform in realizing real-time monitoring, intelligent dispatching, and coordinated control, providing promotable practical experience and technical support for the construction of green shipyards.
