A primary requirement for the transmission system operator is an accurate knowledge of grid
parameters. Moreover, the availability of effective and accurate monitoring tools allows the …

Transformers are one of the most important elements of electrical power systems. In several
conditions, the same transformer is connected to many different networks with different …

In increasingly digitalized and metered distribution networks, state estimation is generally
recognized as a key enabler of advanced network management functionalities. However …

In recent years, the energy form of microgrids is constantly enriching, while the
decentralization requirements of microgrids are constantly developing. Considering the …

With the large number of distributed power sources and the dynamic change of load, the
abnormal parameters of distribution transformers become more and more complicated. So it …

The thesis presents the development of methodologies for the simultaneous estimation of
network parameters (lines and transformers) and compensation of systematic errors of …

The state estimation accuracy will be greatly affected when the measurement gross error
exists. Schweppe-type generalized M-estimator with Huber psi-function (SHGM) can not …

Tap-changing transformer models used in power system studies tend to neglect the change
in the short-circuit impedance of the device at the different tap positions. However, the …

La regulación de tensión es una de las preocupaciones más importantes a tener en cuenta
en el diseño y operación de redes eléctricas. Por esta razón, los transformadores con …
