Socio-technical modelling of customer roles in developing low voltage distribution networks
(CIRED, 07.06.2018)
conferenceObjectThe transition of low voltage (LV) distribution networks towards more intelligent and smart microgrids is dependent on both technical and behavioral factors, thus forming a socio-technical systems change. Sociotechnical ... -
Light-weight IEC 61850 GOOSE based LoM protection for smart grid
(CIRED, 07.06.2018)
conferenceObjectThis paper presents a novel Loss of Mains (LoM) protection method based on IEC 61850 General Object Oriented Substation Event (GOOSE) protocol. With the increased penetration of distributed generation (DG), the requirements ... -
Utilization of a mixture of CTs and current sensors in line differential protection applications
(CIRED, 03.06.2019)
conferenceObjectThe popularity of Rogowski sensors is increasing due to their advantages over conventional CTs. Consequently, network utilities may sometimes end up facing a question whether it would be possible to use line differential ... -
Asymptotic normality of randomized periodogram for estimating quadratic variation in mixed Brownian–fractional Brownian model
(VTeX, 11.05.2015)
articleWe study asymptotic normality of the randomized periodogram estimator of quadratic variation in the mixed Brownian–fractional Brownian model. In the semimartingale case, that is, where the Hurst parameter H of the fractional ... -
Evaluation of renewable energy development in power generation in Finland
(AIP Publishing, 20.12.2013)
