Embodiment Construction
[0076] The present invention will be further described below in conjunction with the accompanying drawings.
[0077] Such as figure 1 Shown is a static voltage stabilization control method based on air-conditioning load, and each step will be described in detail below.
[0078] Step 1: Establish a load model of a single air conditioner based on the equivalent thermal parameters (ETP) model, and calculate the load reduction potential and maximum controllable duration of a single air conditioner while considering the comfort of the human body.
[0079] (1-1) Establish a load model of a single air conditioner
[0080] Establish the relationship between the cooling capacity of the air conditioner and the indoor temperature as follows:
[0081]
[0082] Among them: T in (t) and T in (t+1) are the indoor temperature at time t and time t+1 respectively, T out (t) and T out (t+1) are the outdoor temperatures at time t and time t+1 respectively, Q AC (t) is the cooling capaci...

The invention discloses a static voltage stability control method based on an air conditioner load, and the method comprises the steps: (1), building a single-air-conditioner load model based on an equivalent thermal parameter model, and solving the cut-down potential and maximum controllable time duration of a single-air-conditioner load on the basis of the comfortable degree of a human body; (2), tracking a PV curve of an air conditioner group through a continuous tide flow method, and calculating the static voltage stability margin lambda of the air conditioner group; (3), building a static voltage stability control model of the air conditioner group based on the air conditioner load. The method provided by the invention builds the first-order equivalent thermal parameter model based on the air conditioner load, calculates the voltage stability margin of a system based on the continuous tide flow method, gives consideration to the comfortableness of a user, achieves the static voltage stability control model based on the air conditioner load, and provides the basis for the safe and economic operation of a power grid.
Description
technical field [0001] The invention relates to a static voltage stability control method based on air-conditioning load, which belongs to the power system and automation technology thereof. Background technique [0002] At present, the development of renewable energy and the improvement of energy utilization efficiency have become a consensus in the energy field. However, with the large-scale connection of intermittent new energy represented by wind power and solar power and new loads such as electric vehicles to the power grid, the vulnerability of traditional power grids Increasingly, it has caused voltage collapse accidents worldwide. Due to user habits and other reasons, the air-conditioning load itself has the characteristics of randomness and dynamics, which further deteriorates the load characteristics of the system and has a great negative impact on the stable operation of the grid voltage. [0003] But on the other hand, as an important demand response resource un...
