The energy storage system and secondary equipment for the booster station of this project were integrated and supplied by SIFANG. The provided energy storage system consists of six 3.45MW/6.7MWh storage units, totaling 20MW/40MWh, effectively addressing the randomness and volatility of photovoltaic power generation and enabling off-peak power utilization during peak times. The energy management system of this project is developed based on mature system platform, supporting millions of data points, utilizing a three-tier, two-network professional-grade architecture, and IEC61850 communication protocol. Additionally, it is equipped with a Power Management System (PMS) for energy storage, enabling rapid adjustment and instant response of energy storage, efficiently and precisely controlling numerous PCSs.
