Abstract

The invention provides a power-grid-friendly air conditioner controller and a control method of the power-grid-friendly air conditioner controller. The power-grid-friendly air conditioner controller comprises an air conditioner control MCU module, a power grid parameter detection module, a temperature measurement module, a storage module, a communication module, a function display module and a power supply module. The power grid parameter detection module can detect and store real-time voltages and real-time frequencies of a power grid according to a certain cycle. The temperature measurement module can detect and store the current environmental temperature in real time. The storage module can store two kinds of working mode data. The function display module is used for displaying current power grid parameters, environmental parameters and the working state of an air conditioner. The air conditioner control MCU module is used for adjusting operating parameters of the air conditioner in real time according to changes of the voltages of the power grid and controlling the operating state of the air conditioner. On the premise of not influencing electricity utilization experience of users, an air conditioner load can participate in friendly response of the power grid, and the power-grid-friendly air conditioner controller can increase safe and stable operating capacity of the power grid.

Description

technical field [0001] The invention relates to an air conditioner controller, in particular to a grid-friendly air conditioner controller and a control method thereof. Background technique [0002] The concept of "grid friendly" was first proposed by Professor Thiringer T in Sweden. Subsequently, this concept was mostly used in the field of grid connection of renewable energy, and became an important target for the grid connection of fluctuating new energy sources such as wind power and solar energy, but its clear meaning is not unified. Under the framework of the smart grid system, grid-friendliness has been endowed with a new connotation. The core of its technology is that the power source and load actively coordinate and interact with the grid respectively, so as to improve the balance ability of the power system more economically, quickly and reliably. [0003] Grid-friendliness includes grid-friendly power generation and electricity utilization technologies. The prop...
