摘要
This paper proposes a new approach to construct the maximal steady-state security regions of power systems using optimization. The method is based on DC load flow. For the first time, the maximal steady-state security region-hyperbox is directly computed through a linear programming (LP) model, in which the upper and lower limits of each component forming hyperbox are taken as unknown variables, and the objective is to maximise the sum of each generator's power adjustment range. The proposed approach is tested on the IEEE six-bus and 30-bus systems. The calculation results and comparison show that the new method is superior to the extending method which is the conventional means for constructing maximal steady-state security regions.
