Abstract

The invention discloses a method for evaluating the adjustability of an air conditioning unit participating in demand side response. The method comprises the steps of building an indoor thermodynamic model; under the condition that the single air conditioner participates in the demand side response and does not participate in the demand side response, calculating the operation time and standby time of the single air conditioner according to the initial state of the single air conditioner; comparing the running time not participating in the demand side response and within the duration of the demand side response with the running time participating in the demand side response and within the duration of the demand side response; calculating the adjustability of the single air conditioning unit by combining the cooling power and the energy efficiency ratio of the air conditioning unit, the sum of the adjustability of all air conditioners in the air conditioning unit being the total adjustable capacity; and regulating and controlling the total adjustability on the aspect of power grid control. According to the invention, the adjustability of the air conditioning unit is accurately evaluated, and the high efficiency that the air conditioning unit participates in demand side response is achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution network, in particular to a method for evaluating the adjustable capacity of an air-conditioning unit participating in demand-side response. Background technique [0002] In recent years, electricity consumption has continued to grow rapidly. Existing data show that the world's total electricity consumption in 2019 reached 7,486.61 billion kWh, and the load peak-to-valley difference is also increasing rapidly, requiring more adjustable capacity to reduce the peak-to-valley difference. However, due to environmental considerations, traditional generating sets are being phased out and cannot provide sufficient adjustability for the power system. As a result, maintaining a balance between supply and demand has become increasingly difficult. [0003] To relieve the pressure on power generation and transmission during peak load periods, demand response (DR) is a widely used peak load curtai...
