Embodiment 1

[0033] like figure 1 As shown, a non-industrial air-conditioning flexible load control system includes a load control master station and a demand response terminal;

[0034] The load control master station and the demand response terminal are connected through the network to realize data interaction;

[0035] The load control master station is used to obtain the terminal real-time data uploaded by the demand response terminal, issue the command corresponding to the control strategy of the master station to the demand response terminal, monitor the operation status of the air conditioning equipment, and evaluate the user peak shaving effect after the control execution is completed; the real-time data of the terminal Report to the main station through DL / T 634.5104-2009, and the downlink communication adopts 376.1 protocol;

[0036] Terminal real-time data include: air-conditioning equipment parameters, electricity meter measurement data and environmental parameter data;

[00...

Embodiment 2

[0055] A non-industrial air conditioner flexible load control method, comprising the steps of:

[0056] Step 1. Obtain the real-time data uploaded by the demand response terminal, and send the control command of the master station to the demand response terminal;

[0057] The master station is the initiator of the task, and its operation process mainly includes: the start-up, execution and evaluation of flexible load control. In the three stages of the master station system operation, data interaction with the demand response terminal is required. The terminal obtains relevant device parameters on the user side; sends commands during the regulation execution process and monitors the device operating status; evaluates the user peak-shaving effect after the regulation execution is completed.

[0058] Step 2, the demand response terminal selects the non-industrial air-conditioning flexible load control strategy according to the control command issued by the master station, and co...

Abstract

The invention discloses a non-industrial air conditioner flexible load control method and system. The method is characterized in that three user-side operation strategies of a maximum load strategy, an optimal comfort strategy and a comfort equilibrium strategy are make according to a non-industrial air conditioner control participation way and characteristics of a typical building, so that the user-side comfort is balanced and load capacity is reduced to the greatest extent. Meanwhile, a non-industrial air conditioner load control master station system is established, and a communication network between the master station system and a user side is established, so that a demand response terminal and the load control master station realize data interaction, and therefore, the non-industrialair conditioner flexible load control purpose is achieved, area electricity utilization peak is effectively reduced, and safety and economical efficiency of area power grid integral operation are improved.

Description

technical field [0001] The invention relates to a non-industrial air conditioner flexible load control method and system, belonging to the technical field of intelligent electricity utilization. Background technique [0002] In recent years, with the rapid development of the national economy and the continuous improvement of people's living standards, the sharp increase in air-conditioning load has become an important reason for the deterioration of grid load characteristics and power shortages in summer. In order to meet the ever-increasing demand for air-conditioning loads, the country has to invest hundreds of billions of dollars in the construction of power plants and power grids every year. These power generation and transmission equipment have low annual utilization hours and high peak-shaving costs. Short-term peak power consumption will lead to rising costs of power generation and supply, which is not conducive to the rational use of social resources. The air-condit...
