Method for variable frequency air conditioner participating in power and frequency control of power system

Abstract

The invention relates to a method for a variable frequency air conditioner participating in the power and frequency control of a power system, and the method comprises the steps: data preparation: enabling a market member of a power market before an hour to report a cost curve to a dispatching center, and enabling the dispatching center to calculate load prediction data; dispatching center power generation and consumption joint clearing: employing a power generation and consumption joint clearing model giving consideration to load agent for implementation, enabling the dispatching center to carry out the joint optimization of an AGC set, an non-AGC set and the load agent according to the data of a power generation cost curve, transmitting an optimization result to the market member, enabling the load agent to calculate the real-time electricity price for a governed terminal user, and transmitting the electricity price to a terminal user through a broadcast; real-time power balance: enabling the AGC set to automatically adjust the power generation power according to the imbalance of the total power of the system, thereby achieving the real-time balance of the power of the power system and the stabilization of the frequency of the power system.

Description

technical field [0001] The invention relates to a power frequency control method in a source-network-load interactive environment, and in particular to a method for frequency conversion air conditioners to participate in power system power frequency control. Background technique [0002] With the large-scale access of new energy, the randomness of the power supply side increases, and the pressure on system power regulation caused by load fluctuations and power fluctuations increases. Therefore, the power adjustable load becomes the system's always-to-adjust resource. However, due to the small adjustment amount of a single load entity, the large quantity, and the complex and changeable load characteristics, the end users in a certain area are aggregated to participate in system adjustment through the load proxy method. , which becomes a more reasonable way. [0003] At present, there are many studies on the power adjustment of frequency conversion air conditioners, but users...

This type of load response is a "conditioned reflex" control mode for individual loads, which is likely to cause centralized compensation of electricity demand outside the boundary of the load reduction period, which will have an impact on the system; at the same time, the specific reduction amount within the reduction period is highly random, Increased system power balance burden
