AI Technical Summary

Technical Problem

Existing frequency regulation control methods for energy storage systems do not take into account the temperature rise and capacity differences of battery stacks, resulting in some battery stacks overheating or running out of capacity, thus failing to complete the frequency regulation task.

Method used

By performing real-time weighted calculations on the capacity and temperature rise of the battery stack, low-temperature or low-capacity battery stacks are allowed to operate at high power preferentially, while the power output of high-temperature battery stacks is limited until their temperature is suitable before increasing the power output.

Benefits of technology

It enables constant power operation of the energy storage system throughout the entire time period, improves the system's energy utilization rate, and ensures the completion of frequency regulation tasks.

Abstract

The present disclosure provides a kind of energy storage system frequency modulation control method, device, electronic equipment and storage medium, according to the remaining available capacity of each battery stack and maximum capacity, determine capacity weighting factor;According to the remaining temperature rise of battery stack to reach current-limiting temperature and current-limiting temperature, determine temperature weighting factor;According to the proportion of remaining available capacity corresponding to each battery stack of capacity weighting factor and the proportion of remaining temperature rise corresponding to the battery stack of temperature weighting factor, determine the power distribution proportion corresponding to each battery stack;According to the running power in single step of power distribution proportion and frequency modulation demand power cumulative, determine the sliding average value corresponding to cumulative power total sum to determine the maximum continuous running time of energy storage system, if the time is greater than frequency modulation demand time, then respond to frequency modulation demand.It can realize the constant power operation of energy storage system in whole time period, improve system energy utilization.
