Probiotics were added to goat milk powder, which would not only improve the intestinal flora balance but also would promote human and animal health. In this paper, the effects of different sugars, alcohols, antioxidants on Lactobacillus acidophilus goat milk tablets were investigated by single factor tests based on viable count, suitable hardness, friability, and sensory evaluation. The optimal formulation of goat milk tablets with Lactobacillus acidophilus was obtained: sucrose 7 %, glucose 1.3 %, xylitol 5 %, acesulfame 0.04 %, D-sodium ascorbate 0.06 %, D-mannitol 0.3 %, tea polyphenols 0.018 %, microstalline cellulose 0.4 %. The application of this composition gives good sensory evaluation, high viable lactobacilli count, suitable hardness and friability of the resulting goat milk tablets of Lactobacillus acidophilus.

.In recent years, the development of new energy has become a bottleneck. As a high-quality demand side response resource that can be flexibly dispatched, thermal load can be used to promote the consumption and utilization of new energy. Based on the theory of peak valley electricity price and power demand response mechanism, this paper designs a demand response model of thermal price type, which uses time-sharing heat price to guide users to use heat orderly on the heating side. The simulation results show that the reasonable setting of heat price and satisfaction constraints of different heating modes can effectively change the heating mode of the user side and alleviate the contradiction between the supply and demand of thermal power, reduce the heating cost and realize the economic operation of the system.

With the rapid development of wind power, the randomness and volatility of wind power have also caused severe problems of wind power consumption. The phenomenon of wind abandonment is particularly prominent in the "three north" areas. The environmental protection and controllability of regenerative electric heating provide a way for wind absorption and abandonment. Therefore, this paper proposes a model to promote wind power consumption by using regenerative electric heating. Firstly, the principle and advantages of the heat storage electric heating equipment are described; secondly, the fine modeling of regenerative electric heating is carried out;then, the mode of using regenerative electric heating to promote wind power consumption is designed;finally, an example is given to analyze the wind power consumption effect and the revenue of load aggregators.Therefore, it is verified that this mode can effectively promote wind power consumption and reduce wind abandon generation, and provide reference for alleviating wind abandon and power limit problem.
