Vast and unauthorized penetration of the photovoltaic systems in distribution systems imposed inadequate monitoring challenge to system operators. Although the installation of required monitoring infrastructure does seem as a solution, due to the high installation cost, it is not considered a feasible one, at least for the near future. As an alternative approach, a two-stage method composed of an ANN-based mapping function, and a regression model is presented to detect unauthorized PV connections to the system. A gradient boosting machine is implemented to build the regression model and the corresponding confidence interval. The Monte Carlo simulations are utilized to generate synthetic training data-sets for both models. Finally, the performance of the approach is assessed with real data.

A Computationally Efficient Topology Identifiability Analysis of Distribution Systems Eser, Fatih; Yılmaz, Uğur Can; Dursun, Erk; Cinalioglu, Mustafa Cihan; Göl, Murat (2022-07-01) © 2022 Elsevier B.V.Because of the lack of a proper real-time monitoring system at distribution power networks, topology identification can not be performed properly. While in traditional radial structures the topology is unique, in the presence of an open-ring structure, this issue constitutes a risk for the operation of the system, and the safety of the field staff in contact with the system components. Many studies in literature considers this problem in the scope of observability, however having a compl...
Detection of airport runways in optical satellite images Zöngür, Uğur; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2009) Advances in hardware and pattern recognition techniques, along with the widespread utilization of remote sensing satellites, have urged the development of automatic target detection systems. Automatic detection of airports is particularly essential, due to the strategic importance of these targets. In this thesis, a detection method is proposed for airport runways, which is the most distinguishing element of an airport. This method, which operates on large optical satellite images, is composed of a segmenta...
Efficient and Reliable Multicast of Data in APCO P25 Systems Cigirkan, Gulay; Girici, Tolga; Yüksel Turgut, Ayşe Melda (2015-01-01) In this paper, we investigate an efficient scheme for data multicasting in narrowband public safety radio systems. The proposed scheme uses fountain encoding, in order to avoid feedback messages for each individual packet. We first propose a multistage estimation scheme that is based on slotted random access and that does not require any prior knowledge of number of users. The rest of the proposed scheme consists of iterative transmission and feedback/estimation phases. In feedback phases, the base station ...
A framework for distributed intrusion detection systems Öztosun, Ümit; Koçyiğit, Altan; Mumcuoğlu, Erkan; Department of Information Systems (2002) Emergence of intrusion detection systems (IDSs) has leveraged the security of infor mation systems. However, they also introduced new problems. Plethora of intrusion detection systems are in common use today, using various different ways and tech niques for intrusion detection. It is not uncommon to see an information system uti lizes different IDSs, in order to combine advantages and to reduce disadvantages of individual systems. This often results in a confusion of systems that output informa tion in diff...
Examination of Target RCS Characteristics in FDA Radars Cetintepe, Cagri; Demir, Şimşek (2014-07-11) This paper reports on the preliminary analysis of frequency diverse array (FDA) radars for simple target geometries. The radar system employs an FDA and a isotropic element as the transmitter and receiver antennas, respectively, and illuminates a target consisting of an arbitrary arrangement of ideal point scatterers. After establishing a signal model for the voltage waveform received by this radar system, the study then considers particular target arrangements and compares the average received power to tha...
