In order to evaluate the comprehensive ability of non-intrusive load monitoring non-intrusive load monitoring terminals, the comprehensive evaluation method of non-invasive load identification terminals is studied. Firstly, by analyzing the main influencing factors of non-invasive load identification terminal in combination with the practical application, the evaluation system of non-invasive load identification terminal and the definition of each index are determined. Then the combined weight of the evaluation system is designed, based on the analytic hierarchy process (AHP) and the entropy weight method. Finally, the evaluation method is applied to the actual terminal and applied to the terminal delivery verification of the actual project to verify the feasibility and practicability of the evaluation method.#$NLKeywords: Non-intrusive load monitoring, analytic hierarchy process, entropy method, evaluation system
