The invention relates to a novel integrated energy management and control method for deep user-side energy usage optimization. The method is characterized by comprising the following steps: step one,carrying out ultra-short-term prediction on new energy generation, matching generation prediction with ultra-short-term load prediction, and adjusting cold and thermal loads to realize complementary source-load control; step two, according to a proportion optimization strategy of several kinds of energy, realizing hour-level optimized scheduling and self-approximate optimal control of different cold and thermal sources by using a coordination control technique of cold-thermal load time-sharing matching of cooling-heating-power combined supply; step three, according to a self-approximate optimal control strategy of the environmental temperature, adjusting the temperature indexes of the cold and thermal energy to achieve an objective energy conservation; and step four, turning on and off anair conditioner regularly. According to the invention, a self-approximate optimal effect of usage of the new energy, electric energy, and the cold and thermal energy is realized based on an interactive energy usage control strategy, so that the energy usage becomes economic.
