Robust optimizing method for power generation plan under uncertain environment

Abstract

The invention discloses a robust optimizing method for a power generation plan under an uncertain environment. Uncertain parameters are determined according to the overall requirements in the power generation plan compilation under the uncertain environment; an uncertain optimization model of a power generation plan is established by using robust optimization; uncertain optimization problems are converted into definite optimization problems; an adjustable middle variable result is calculated; and an active power of an ordinary power generation set is resolved so as to generate the result of the power generation plan ultimately. According to the robust optimizing method for the power generation plan under the uncertain environment, the robust optimization is applied to the power generation plan in which the uncertainty is considered; the power generation plane obtained by the optimization is adaptive to all possible operation scenes in an uncertain set and has an extremely strong robust property, thus the engineering can be realized conveniently.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a robust optimization method for power generation planning in an uncertain environment. Background technique [0002] In recent years, with the country's requirements for the construction of smart grids, intelligent dispatching has developed rapidly. Power generation planning is an important part of intelligent dispatching. Reasonable power generation planning arrangements are the premise and basic means to ensure the safe and economic operation of power grids. The key content is the start-stop optimization and output distribution of the generator set, which is divided from the time sequence. In the day-ahead period, optimize the start-stop plan to meet the system reliability requirements; in the real-time period, optimize the active power plan of the unit to meet the real-time load demand. The traditional power generation planning ...
