A correct power network topology model is essential from viewpoint of various dispatching control applications. This model is created with use of states of switching devices which are gathered in real-time. In some circumstances, there can be errors in the obtained power network connectivity model. The paper deals with the verification of the mentioned(More)
Domain Specific Languages gain increasing popularity as they substantially leverage software development by bridging the gap between technical and business area. After a domain framework is produced, experts gain an effective vehicle for assessing quality and performance of a system in the business-specific context. We consider the domain to be(More)
Excessive reactive power flows are an important problem in a power system. Optimization of reactive power flows in the system allows reducing them. This paper deals with optimization of reactive power flows in the national power system. Effects of two variants of this optimization are presented. One of them is when voltage magnitudes at generation nodes,(More)
Data redundancy is crucial for the success of state estimation (SE): for achievement of good and reliable estimates, for efficient processing bad data. The paper presents the review of the methods for measurement placement design assuring adequate data redundancy levels for state estimation. For each of the considered methods, the made assumptions, utilized(More)
