For the sake of exploring how to apply new flexible resources to power system efficiently, it is urgent to study the comprehensive value of different flexible resources in typical application scenarios of power system. In this paper, a flexible resource value comprehensive evaluation index system is established from three dimensions: technical value, economic value and application value. Combined with the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method, a comprehensive evaluation model of power system flexible resource value in typical application scenarios is constructed to evaluate the current value of flexible resources in China. The results show that the virtual power plant shows the highest flexible resource matching degree in the peak shaving and valley filling scenario and the auxiliary service scenario, and the electrochemical energy storage shows the highest flexible resource matching degree in the safety support scenario.
