A METHOD AND SYSTEM FOR CONTROL OF SMOOTHING THE ENERGY STORAGE IN WIND PHTOVOLATIC POWER FLUCTUATION BASED ON CHANGING RATE

摘要

The invention relates to a method and system for smoothing the energy storage wind and photovoltaic power fluctuation based on rate control, including: reading and processing data; determining the signal change rate of the dynamic slope limiter; calculating the smoothing target value of the wind and photovoltaic total power; calculating total power demand of battery energy storage power station; and outputting data. The invention can effectively suppress wind and photovoltaic power fluctuation under the fluctuation rate limited value, can effectively smooth wind and photovoltaic power output. Thus it smoothens wind and photovoltaic power output, reduces the energy storage battery burden, and effectively controls battery energy storage power station system.
