Abstract

The invention provides a regional power grid power dynamic balancing method based on an HVAC system. The method comprises the following steps of: (1) identifying a regional power grid power requirement based on system frequency signals; (2) carrying out dynamic classification on the HVAC load based on an HVAC system energy storage adjusting module, and assessing the HVAC load response capability based on a calculation power index and an energy index; and (3) adjusting the HVAC load power according to an HVAC system power adjusting model, adjusting the load power by controlling the on-off state of the HVAC load, and responding to the regional power grid power requirement. According to the invention, the HVAC system widely accessed in the electric power system is fully utilized to support power balance of the regional power grid. When power unbalance occurs in the regional power grid, the load power is controlled by the dynamic adjustment of the on-off state of the HVAC system, the regional power grid power requirement is responded, and the frequency stability of the regional power grid is maintained.

Description

Technical field [0001] The invention relates to a method for dynamic balance of power grids, in particular to a method for dynamic balance of power of a regional power grid based on an HVAC system. Background technique [0002] With the continuous expansion of the scale of renewable energy access to the grid, traditional system power balance adjustment methods are difficult to effectively suppress the frequency fluctuations caused by the large output of renewable energy. This leads to the increase in the demand for grid rotation and the reduction of system operation economy. The HVAC system has the characteristics of fast response, strong controllability, and wide application range. It is a typical user-side mixed energy of cold, heat and electricity. The HVAC system has a large thermodynamic adjustment range, and the change of the switch state in a short time will not affect the user's normal use and comfort. Therefore, this article chooses the HVAC system as the control object...
