Embodiment Construction
[0029] The implementation of the smart grid load detection and identification method based on the joint matching of steady-state and transient characteristics of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] The method of the present invention is based on joint matching of steady-state and transient characteristics, and needs to establish a load characteristic database. Select a typical smart grid load device (can be selected according to the use environment). The load feature library includes several load devices that appear in the detected grid object. Each load device in the load feature library includes the following characteristic data: When the load is in steady state Active power, reactive power, harmonic current (3rd and 5th), transient current data during on and off periods.
