Accuracy Evaluation Method of Non-intrusive Load Identification Based on Load Component Analysis

The accuracy of non-intrusive load identification (NILI) is the core index to measure the ability of load identification. The traditional identification result evaluation method based on statistics has high requirements on detection data and detection environment, so it is difficult to realize the rapid evaluation of load identification equipment. From the perspective of product application and testing requirements, the identification accuracy evaluation method of NILI equipment was studied. Based on the comprehensive analysis of the identification results of load identification equipment, a NILI accuracy calculation method based on load component analysis is designed, and the corresponding load identification test method and system are constructed. Through the test and evaluation analysis of a NILI module, the comprehensive evaluation ability of the evaluation method for the accuracy of identification equipment is verified, which provides a feasible method for performance evaluation and quality analysis of NILI products.
