Commercial building central air-conditioning load control system interacted with power grid and method thereof

Abstract

The invention relates to a commercial building central air-conditioning load control system interacted with power grid and a method thereof. The system comprises a data acquisition device, a controllable load calculation device, a control strategy generation device, a strategy plane expert base, a control strategy execution device, a display interface device and an alarm processing device, wherein the controllable load calculation device, the data acquisition device and the control strategy execution device respectively communicate with terminal equipment. Bidirectional interaction between commercial building central air-conditioning and the power grid is realized, so that power supply enterprises can formulate a reasonable load control plan according to the controllable load capacity fed by each commercial building central air conditioner, and the peak clipping function of the commercial building central air-conditioning on the power grid is fully utilized; and moreover, the commercial building central air-conditioning fully exerts demand-side response, the suitability of a building environment is guaranteed, energy conservation of the commercial building is realized, and the economical efficiency of overall power consumption is improved.

Description

technical field [0001] The invention relates to the technical field of electricity utilization in electric power systems, in particular to a central air-conditioning load control system for commercial buildings interacting with a power grid and a method thereof. Background technique [0002] With the rapid development of the global economy and the continuous improvement of people's living standards, various types of air conditioners have been widely used. The air conditioner load in some large and medium-sized cities and economically developed provinces in my country has accounted for more than 30% of the maximum load in summer. region has even exceeded 40%, and will show a high-speed growth trend in the next few years. Affected by the air-conditioning load, the electricity load of each power grid increases rapidly, and the peak-to-valley difference further widens. The sharp increase in air-conditioning load has become an important reason for the deterioration of grid load ch...

AI Technical Summary

Problems solved by technology

[0005] 1. The adjustable load capacity of the central air-conditioning load in commercial buildings lacks scientific calculation methods, does not comprehensively consider various factors such as air-conditioning operation and environment, and lacks objective basis for air-conditioning load regulation

[0006] 2. There is a lack of dynamic exchange and communication of information between the central air conditioners in commercial buildings and the power grid, resulting in the isolation of air conditioning load adjustment planning and execution from the power grid, and the inability to maximize the peak-shaving effect of central air conditioners in commercial buildings on the power grid.

[0007] 3. Since there is no real-time tracking, monitoring and calculation of environmental parameters in the process of air-conditioning load adjustment, the air-conditioning control strategy cannot dynamically change with environmental conditions, and it is difficult to ensure the coordination between air-conditioning load adjustment and the environment
