摘要：

According to the influence of wind power integration on the security and stability of power system, deterministic unit commitment is currently used to economic dispatch, which takes reserve capacities to cope with the wind power fluctuation. Compared with the traditional deterministic unit commitment, this paper adopts the scenario-based method to build the probabilistic unit commitment model. A method of wind irregular probabilistic distribution model based on "wind speed-wind power" relationship is proposed to describe the uncertainty of wind power with multiple scenarios. The paper has deeply research on the similarities and differences of deterministic unit commitment and probabilistic unit commitment, and analyzes the influence of two scheduling schemes on the system operation cost, solving efficiency and the ability of system acceptance wind power, respectively. A modified IEEE 118-bus test system is used to make simulation and verification, comparison results of two method provide strong technical support for the engineering community to the operation of probabilistic unit commitment.
