Control method of frequency of power system attended by wind energy and light energy storage combined power generation system

Abstract

The invention belongs to the field of power generation of new energy and particularly relates to a control method of the frequency of a power system attended by a wind energy and light energy storage combined power generation system. The control method comprises the following steps of: A, judging the conditions of the power system and a control area where the wind energy and light energy storage combined power generation system is positioned; B, controlling a timer to time in the control area or clearing zero; and C, adopting a control strategy for the wind energy and light energy storage combined power generation system. Through the control method provided by the invention, the wind energy and light energy storage combined power generation system is allowed to attend the frequency modulation of the power system so as to provide a support for the frequency stabilization of the power system and reduce the pressure caused by new energy power station grid connection to the safe and stable operation of the power system.

Description

technical field [0001] The invention belongs to the field of new energy power generation, and in particular relates to a method for controlling the frequency of a wind-solar-storage combined power generation system participating in a power system. Background technique [0002] The power system is a complex dynamic system, and its safe and stable operation essentially requires a balance between power generation and load demand at all times. If the power system cannot be effectively controlled and there is an imbalance between supply and demand, it will cause system frequency fluctuations, affect the reliable power consumption of loads, and even cause large-scale accidents in the system. [0003] New energy represented by wind power and photovoltaics is gradually becoming an important energy resource in my country. While it plays an important role in meeting energy demand, improving energy structure, reducing environmental pollution, and protecting the ecological environment, ...
