| Abstract_FL | The accurate calculation of air conditioning load power is crucial for implementing its demand-side management.For this purpose,an air conditioning load identification method for industrial and commer-cial users based on feature recognition and variational auto-encoder network is proposed.For continuous daily load curves of customers,a similarity measure of load curve shape based on locally weighted linear fitting and fast dynamic time warping is proposed to achieve the measurement of load curve shape fea-tures.An ordering points to identify the clustering structure-based algorithm is proposed to achieve the classification of load curves.For the daily load sequence of users under the same classification type,a variational auto-encoder network-based air conditioning load identification method is proposed to achieve accurate calculation of the power consumption for air conditioning loads.The effectiveness of the proposed method is verified by the power consumption data of processing and manufacturing industry and commer-cial office building users in a city of Zhejiang Province.The simulation results show that the proposed method can effectively identify the user's power consumption of air conditioning loads without the need of high-frequency sampling data of smart meters and obtaining the user's electrical equipment information and electrical behavior in advance,which provides a basis for quantifying the users'adjustable potential of air conditioning loads to participate in demand response. |
