Air conditioning load coordination control method of stabilizing power fluctuation of micro-grid linking-up road

Abstract

The invention relates to an air conditioning load coordination control method of stabilizing power fluctuations of a micro-grid linking-up road. The method includes the following steps: 1) calculating an air conditioning an aggregation power control target for air conditioning clusters on the basis of low pass filter principles; and 2) for an air-conditioning individual, coordinately distributing the air conditioning an aggregation power control target to all air conditioning loads on the basis of market control. Compared with the prior art, the method has the advantages that different comfort requirements of users can be met, user privacy and power utilization safety can be fully protected, and thus the user experience of implementation of the method can be improved. The method greatly simplifies downlink control for a control center, only needs to measure power of a linking-up road, and effectively reduces the implementing cost.

Description

technical field [0001] The invention relates to a method for stabilizing power fluctuations of a microgrid tie line, in particular to an air conditioner load coordination control method for smoothing power fluctuations of a microgrid tie line. Background technique [0002] Intermittent power sources such as wind power and photovoltaics will have adverse effects on the stability of the power grid and power quality after they are connected to the grid. With the increasing penetration rate of renewable energy, how to stabilize the power fluctuation of renewable energy has become an important research topic of smart grid. At present, energy storage equipment is mainly used to smooth grid-connected power. However, energy storage equipment is expensive and still does not have an economic advantage. [0003] In recent years, researchers have noticed that thermostatically controlled loads (thermostatically controlled loads, TCL) such as air conditioners, heat pumps, and water heat...

Problems solved by technology

If the switch control is adopted, the user needs to expose the control right of the device switch to the outside, which has serious information security problems

[0007] 3) Certain control strategies require TCL equipment and thermal parameter model information of buildings, but it is not only difficult to obtain a large number of TCL equipment models in practice, but also difficult to guarantee the privacy of users
