  • Abstract:

        With large-scale integration of renewable energy to power system, its uncertainty has brought great challenges to economic dispatching. To solve this problem, a data classification method for modeling temporal correlation of wind power is put forward, and the versatile-copula distribution is applied to describe the correlation. On the basis of those improvements, the chance constrains and over/under estimation punishment model are presented, and a stochastic optimization model of minimizing generating cost is given in the meantime. After that, through conversions of objective functions and constraints, the stochastic optimization model is transformed into a linear convex problem, and the successive linearization program is applied to solve it accurately. Finally, case study is carried out in modified IEEE-30 bus and IEEE-118 bus system, which verifies the effectiveness of the proposed scheduling method in terms of fitting accuracy and generating cost.
