Embodiment

[0128] The main idea of ​​the fixed-speed compressor control strategy is to control the on-off state based on the size of VSOC, and give priority to shutting down the virtual energy storage with higher VSOC during operation.

[0129] Using MATLAB as the simulation platform, the implementation steps of the program mainly include: data state refresh, processing of VSOC over-limit problem, generation of control queue Q based on VSOC size, calculation of whether the power shortage is met, generation of opening queue based on impact power, processing of related opening queues, virtual The energy storage status is updated iteratively.

[0130] Set the power gap to 30kW, and the protocol control time to 180min. Take 100 fixed-speed compressor air conditioners as the scheduling objects. The specific parameters are: 100 fixed-speed air conditioners, the initial state VSOC is uniformly distributed from 0 to 1; the switching function is an integer distribution from 0 to 1; the communica...

Abstract

The invention discloses a constant-speed air conditioner control strategy based on virtual state of charge priority. The strategy comprises steps of based on an equivalent thermal parameter model modeling method, proposing a thermal parameter part of a virtual energy storage model, deriving related indexes, based on temperature control load operation characteristics, carrying out mathematical description on indexes of an electric power parameter part, and integrating the electric power parameter part and the thermal parameter part to form a temperature control load virtual energy storage model; discretizing and linearizing the virtual energy storage model; proposing a VSOC priority constant-speed compressor type control strategy; and obtaining equipment parameters and operation states of all the constant-speed air conditioner users participating in scheduling, setting power shortage and control right yielding duration of a power grid, and obtaining a specific control function. The potential that the constant-speed compressor type temperature control load participates in demand side response is fully excavated.

Description

technical field [0001] The present invention relates to the field of air conditioner load cluster scheduling, mainly including optimization control, load transfer, demand side response, temperature control load, virtual energy storage and other fields. Constant speed air conditioning control strategy. Background technique [0002] Demand side response is a power consumption mode in which users actively accept grid signals for interaction. The promotion of advanced measurement systems makes it possible to apply temperature control load control strategies and cluster scheduling on a large scale. Fixed-speed compressors are mainly used in air conditioners in homes and are also the core components of air conditioners. The constant speed air conditioner has a fast response speed and a large response potential. From the three indicators of reducibility, controllability and acceptability, the ordinary fixed-speed air conditioner is regarded as a typical representative of the fix...
