Problems solved by technology

[0006] Most of the existing data analysis methods under the power grid system are single-angle data analysis under simple logic, such as: only data screening with specified weights, and data screening cannot be combined with other external factors in a flexible and diverse manner; in addition, directional To accurately extract the load generated by air-conditioning equipment from the database, it is necessary to plan and count the equipment in detail, which will consume a huge workload

Embodiment Construction

[0029] as the picture shows,

[0030] 1. Selection method of air conditioning load data reference value

[0031] The load data generated by the air-conditioning equipment on a certain day is selected as the reference data row. The data selected in this plan are: the load curve data of the provincial power company’s central air conditioner on August 19, 2016 is used as the reference for cooling load, and the data for heating on November 22, 2016 is used as the reference for heating. Can reflect the temperature characteristics in line with the seasons. The central air conditioners of the Provincial Electric Power Company operate normally throughout the day, so the power data generated is relatively stable, and because it is an independent power supply, its working power will not be affected by changes in other electrical equipment. To sum up, it is more characteristic to select the load data generated by the equipment on the day.

Abstract

The invention belongs to the technical field of load extraction, and particularly relates to an air conditioner load extraction method. The main purpose of the invention is to formulate a certain measurement standard when extracting load data of power users in a power grid system, and extract load data generated by air conditioner equipment from the overall load data according to the definition ofa model; and then the influence degree of the air conditioner load on the overall load is determined, then an actual method is formulated to control the change of the load (by adjusting the air conditioner temperature, controlling the electric charge and the like), and finally a certain influence is generated on the overall load, so that the effect of peak load shaving is achieved.

Description

technical field [0001] The invention belongs to the technical field of load extraction, and in particular relates to a method for extracting air-conditioning loads. Background technique [0002] In the power grid system, it is of great practical significance to perform an operation of "shaving peaks and filling valleys" for the curves generated by load data records. For example, if a certain city needs 210 million kWh of electricity consumption, and each generator can generate 50 million kWh of electricity, then in order to meet such electricity demand, it is necessary to start 5 generators to meet the demand , and the total power generation is 250 million kWh, which is far greater than the electricity demand of 210 million kWh, resulting in a waste of 40 million kWh of electricity. Therefore, if the extra 10 million "peak" power can be cut down, only 4 generators can be started to meet the power demand and reduce the cost of power generation. [0003] The load generated b...
