Abstract
In order to integrate various operation information and accurately explore the operation situation of a power system, a dynamic comprehensive evaluation method considering index screening is proposed, and based on this, a situation awareness (SA) system based on the new energy power system is established. Firstly, aiming at the problem of information overlap among indicators, the existing indicator system of the new energy power system is quantitatively screened and reconstructed by the indicator screening method based on Measure of Sampling Adequacy (MSA) and Kaiser–Meyer–Olkin (KMO) test statistics. Afterwards, the dynamic evaluation method incorporating the subjective and objective is used to calculate the evaluation score and identify the stable operating state of the system. Finally, qualitative trend analysis and judgment are carried out on the evaluation scores, and the effect of power system situational awareness is verified by the improved IEEE 39 system. The results demonstrate that this method can be useful for improving the stability state sensing accuracy of a new energy power system.
