Abstract

The invention relates to a method for a battery energy storage response frequency modulation signal in defined states of charge, and relates to the technical field of battery energy storage frequencymodulation power generation. The method includes the following steps: obtaining the states of charge defined at the beginning and the end of a time period and the battery energy storage frequency modulation basic information; and establishing, by using a dynamic programming method, a mathematical model of the charging-discharging power of the battery energy storage response frequency modulation signal, and working out the optimal solution of the charging-discharging power of the battery energy storage tracking frequency modulation signal by using an objective function to maximize the battery energy storage tracking accuracy. The method is helpful to improve the system frequency stability.

Description

technical field [0001] The invention relates to the technical field of power grid frequency modulation, in particular to a method for limiting the response of battery energy storage to frequency modulation signals in a state of charge. Background technique [0002] At present, the development of new energy has become the core content of promoting energy transformation in many countries and an important way to deal with climate change. It is also an important measure for my country to promote the revolution of energy production and consumption and promote energy transformation. In recent years, my country's new energy power generation industry has developed in an all-round way, and its scale has continued to grow. It has entered the stage of large-scale incremental replacement and regional stock replacement, and the development of wind power and photovoltaic power stations has advanced by leaps and bounds. However, new energy power generation has the characteristics of volati...
