Utility Storage System
Overview
To address the issues of randomness and volatility in renewable energy generation, as well as insufficient frequency and voltage support in the new power system, we propose high-voltage cascading and low-voltage paralleling energy storage system solutions. These solutions offer excellent load regulation performance and high-efficiency energy storage, enhancing the grid's capacity to absorb renewable energy and improving the safe and stable operation of power systems.

Typical Cases
Hebei Photovoltaic Power Generation Project Ancillary Energy Storage (20MW/40MWh)
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.
