Abstract

The invention discloses an electric power system dispatching method and device. The method comprises the steps: Latin hypercube sampling is performed on wind power and load, the scene amount is reduced through scene reduction method, and a scene set having preset scene amount is obtained; and optimal cost of each scene is calculated through standard difference algorithm, self-learning selection operation and longitudinal cross operation. Then an optimal result of each scene is effectively and reasonably calculated. According to the invention, the resolution precision and efficiency are improved, and optimized effect of a regional interconnected power system is improved. Correspondingly, the electric power system dispatching device provided by the embodiment of the invention has the above technical effect as well.

Description

technical field [0001] The present invention relates to the technical field of power dispatching, and more specifically, to a power system dispatching method and device. Background technique [0002] With the continuous expansion of the scale of the power system, the initial formation of the national grid, and the injection of large-scale wind power into the grid, the regional interconnected power system has brought huge economic benefits to the society, but the power system dispatch is also facing extremely severe challenges. [0003] The essence of power system scheduling is a nonlinear optimization problem. With the rapid expansion of the power system scale, the dimension of the nonlinear optimization problem that needs to be solved is also increasing. At present, the research on regional interconnected dynamic economic dispatch considering the uncertainty of wind power has just started. Due to many uncertain factors, it is difficult to solve and the calculation efficienc...
