Abstract

The present invention disclosed a three -phase distribution grid adjustment method based on the frequency conversion air conditioner, including the following steps: S10, which calculates the trend and three -phase imbalances to determine the state of the distribution network, the voltage and imbalance of each node of the distribution network,Adjust the required power S20, according to the state of the air conditioner, use the Affinity Propagation (AP) cluster algorithm to classify the air conditioner to determine the priority of participating in the adjustment; according to the power required and the priority required by the adjustment, determine the required required to adjust the required adjustment requiredThe number of air conditioners and the adjustment power of each one; S40, change the compressed motor frequency of the air conditioner based on the adjustment power; S50, update the room temperature, and prepare the next adjustment.The invention regulates the power distribution network through air -conditioning management to ensure the quality of electrical energy.

Description

technical field [0001] The invention belongs to the field of power electronics, and in particular relates to a three-phase distribution network voltage regulation method based on variable frequency air conditioners. Background technique [0002] With the increasingly severe environmental problems and energy shortages, the state has vigorously promoted changes in the energy consumption structure. In recent years, the photovoltaic and electric vehicle industries have developed rapidly. Since 2011, China, Japan and the United States have begun to vigorously develop the solar photovoltaic industry, which has promoted the rapid development of the global photovoltaic industry. In 2017, the global photovoltaic market developed rapidly. In 2017, the newly installed capacity exceeded 98GW, an increase of 28.95% over the previous year. The global cumulative installed capacity has exceeded 402.5GW, showing a good momentum of development. Traditional markets, such as the United States ...
