Embodiment 1

[0099] Embodiment 1: see figure 1 , figure 2 , a peak regulation control method based on an air-conditioning aggregation model, the control method comprising the following steps:

[0100] Step (1): Establish a load model of a single air conditioner based on the principle of energy conservation and the operating characteristics of the air conditioner.

[0101] (11) The equivalent thermal parameter model of the inverter air conditioner load is expressed as follows:

[0102]

[0103] In the formula, T in (t) is the indoor temperature at time t, °C; T out (t) is the outdoor temperature at time t, °C; Q AC (t) is the air-conditioning cooling capacity at time t, kW; R is the equivalent thermal resistance of the air-conditioning room, Ω; C is the equivalent heat capacity of the air-conditioning room, F.

[0104] (12) During the working period of the inverter air conditioner, as the frequency increases, the cooling capacity and electric power of the inverter air conditioner w...

Abstract

The invention relates to a peak shaving control method based on an air conditioner aggregation model. The peak shaving control method based on the air conditioner aggregation model is characterized in that the peak shaving control method comprises the following steps that (1) a load model of single air conditioner is built according to the energy conservation principle and air conditioner running characteristics; (2) unified dispatch and control are conducted on air conditioner groups through load aggregators, the aggregation model of the air conditioner groups is built, and peak shaving potential of an aggregated air conditioner load is evaluated; (3) in the current market, a minimum electric power company dispatching cost is taken as the objective function, and dispatching plans of next-day peak shaving time periods are made; and (4) in the process of real-time dispatching, the profits of the load aggregators and the comfort level of users are considered together as a whole to achieve optimized control of the aggregated air conditioner load. According to the peak shaving control method based on the air conditioner aggregation model, the technical scheme achieves centralized dispatching control over the air conditioner groups, load-side resources are exploited sufficiently, and the investment pressure of power network facilities is relieved.

Description

technical field [0001] The invention relates to a control method, in particular to a peak-shaving control method based on an air-conditioning aggregation model, and belongs to the technical field of electric power systems and automatic control thereof. Background technique [0002] The development of renewable energy and the improvement of energy utilization efficiency have become important research contents in the field of energy. With the large-scale connection of new loads such as wind power and solar power generation and electric vehicles to the power grid, and the rapid growth of short-term peak loads, the problems of power grid peak regulation and safe operation are becoming more and more serious. The traditional single-increase The practice of peak shaving power supply is costly and has a great impact on the environment. [0003] The air conditioning load is an important part of the system peak load, especially during the summer peak load period. Statistical results...
