A flexible load scheduling control method for AGC

Abstract

The invention relates to a flexible load dispatching control method for AGC. According to the invention, flexible loads are adopted to participate in system dispatching, the flexible loads are taken as control objects, the balance between the loads and a power supply is achieved by adopting a dispatching method applicable to the type of loads, the coordinated operation between the flexible loads is realized, the maximum consumption of clean energy is realized, and the waste is avoided. A consumption region utilizes the scheme to store heat and consumes generated electric energy. The kind of source-load interaction is an active behavior, and changes a situation that the power supply passively adapts to the loads in the past. When the flexible loads cannot meet the power excess, a buffer region abandons the consumption of partial new energy.

Description

technical field [0001] The invention belongs to the field of active power scheduling of power systems, and relates to an AGC flexible load scheduling control method. Background technique [0002] The "Three Norths" area has large installed capacity and wide distribution of new energy, and the problem of new energy consumption is particularly prominent. The power grid regulation is facing new challenges. The traditional dispatching operation control mode has been unable to meet the future power demand, which shows that wind power has the ability to The "load" of the anti-peak shaving characteristic further increases the difference between the peak and valley of the load, which affects the load characteristics of the system, and makes the system increase more rotating reserves to ensure the consumption of local wind power. How to reduce the phenomenon of abandoning wind and light due to insufficient adjustment capacity of the power system, and how to promote the consumption an...

Problems solved by technology

The current AGC is based on the AGC scheduling of thermal power, and the scheduling measures of the auxiliary output of the electric heat storage element are not included in the AGC scheduling control. The thermal element is included in the AGC scheduling, resulting in a deviation in the combination of the two, which cannot better increase the consumption of new energy

[0004] Since the conventional AGC adjustment can only adjust the output of thermal power units, and because clean energy generates a large amount of power and is seriously wasted, in order to accommodate new energy as much as possible, an AGC scheduling control method with flexible load participation is proposed
