As renewable energy penetration rises in modern power systems and load variability grows increasingly complex, instability issues—especially frequency fluctuations—have become more prominent. Intelligent commercial and industrial energy storage systems address this challenge by leveraging AI to boost grid - frequency regulation efficiency and accuracy. They enable real - time frequency monitoring, millisecond - level charge/discharge responses, intelligent scheduling with continuous optimization, and adapt to complex operating conditions—strengthening grid stability and ensuring safe, reliable power system operation.

1 Demand Analysis
1.1 Functional Requirements

When designing grid - frequency regulation systems for intelligent commercial/industrial energy storage, the first step is defining core functions to ensure timely, accurate responses to grid frequency changes and maintain stability. Key requirements include:

Real - Time Frequency Monitoring: Equip high - precision sensors to capture minute frequency shifts and transmit data to the central processing unit instantly.

Intelligent Scheduling Algorithms: Deploy advanced models (fuzzy logic, genetic algorithms, deep learning) for smart charge/discharge decisions—balancing regulation effectiveness and energy efficiency.
Grid Operator Communication Interface: Provide standardized interfaces for seamless integration with grid dispatch centers to receive regulation commands and report system status.

1.2 Performance Requirements

To ensure the efficiency and reliability of the grid frequency regulation system for intelligent commercial and industrial energy storage systems, the following performance indicators must be met:

Response Time: The time from when the system receives a frequency deviation signal to when it starts adjusting the charging/discharging state shall not exceed 100 milliseconds, enabling a rapid response to grid frequency changes.
Frequency Regulation Precision: After frequency deviation compensation, the grid frequency should stay within ±0.01Hz of the target frequency, ensuring the stability of the power system and power supply quality.
System Reliability: The system must have high reliability and fault tolerance. It should maintain normal operation even under extreme weather or sudden situations, with the annual average downtime not exceeding 2 hours.
Adaptability: The system should automatically adjust the frequency regulation strategy under different load conditions (e.g., peak periods, off - peak periods). This ensures effective participation in grid frequency regulation in any situation, enhancing the grid’s flexibility and resilience. Additionally, the system should have a certain degree of scalability and upgradeability to adapt to future power market and technological development needs.
