Abstract: A reserve optimization method and apparatus based on a support outage event constrained unit commitment. The method includes the following steps: step 1: running a basic unit commitment reserve optimization model to obtain a basic unit commitment dispatch result; step 2: establishing a committed capacity outage probability table (CCOPT) based on the dispatch result, calculating the loss of load probability (LOLP), and identifying the marginal events therefrom; and step 3: adding linear constraints corresponding to the marginal events to the reserve optimization model to obtain a new dispatch result, and returning to step 2 till the result meets the LOLP requirements. Multiple compromises in the problem are considered, and the LOLP constraint is simplified such that the model can be accurately and efficiently solved.

Abstract: In the present invention, a sugar product containing L-arabinose and preparing and using methods thereof are provided. The sugar product comprises an edible sugar particle and an L-arabinose enclosing a surface of the edible sugar particle. The edible sugar particle has a particle diameter of 0.15 mm˜0.25 mm; the L-arabinose has an enclosing thickness of 0.001 mm˜0.08 mm; and in each mass part of the sugar product, the edible sugar particle accounts for 80%˜99% in mass percentage, and a dry matter of the L-arabinose accounts for 1%˜20% in mass percentage. With the solution as provided in the present invention, the uniformity of distribution of the L-arabinose on the surface of the edible sugar is improved.

Abstract: The invention discloses a healthy sucrose product and a method for fabricating the same. The sucrose product mainly consists of sucrose and L-arabinose, wherein sucrose has a mass percentage of 70-99.99%, and L-arabinose has a mass percentage of 0.01-30%. The method for fabricating the sucrose product mainly comprises the steps of: sufficiently mixing solid sucrose and L-arabinose crystals; or mixing solid sucrose and L-arabinose solution and then drying the resulting solution. In the present healthy sucrose product, L-arabinose is added into sucrose for suppressing invertase's activity, so that the human body's absorption of sucrose is reduced to achieve a healthy intake of sugar. In this manner, the problems of hyperglycemia, dental caries, and obesity, which otherwise may occur after the intake of sucrose, are solved.
