Anagnostou G, Boem F, Kuenzel S, Pal BC, Parisini Tet al., 2018, Observer-based Anomaly Detection of SynchronousGenerators for Power Systems Monitoring, IEEE Transactions on Power Systems, ISSN: 0885-8950

This paper proposes a rigorous anomaly detectionscheme, developed to spot power system operational changeswhich are inconsistent with the models used by operators. Thisnovel technique relies on a state observer, with guaranteedestimation error convergence, suitable to be implemented in realtime, and it has been developed to fully address this importantissue in power systems. The proposed method is fitted to thehighly nonlinear characteristics of the network, with the statesof the nonlinear generator model being estimated by meansof a linear time-varying estimation scheme. Given the relianceof the existing dynamic security assessment tools in industryon nominal power system models, the suggested methodologyaddresses cases when there is deviation from assumed systemdynamics, enhancing operators’ awareness of system operation.It is based on a decision scheme relying on analytical computationof thresholds, not involving empirical criteria which are likely tointroduce inaccurate outcomes. Since false-alarms are guaranteedto be absent, the proposed technique turns out to be very usefulfor system monitoring and control. The effectiveness of theanomaly detection algorithm is shown through detailed realisticcase studies in two power system models.

Nduka O, Pal BC, 2017, Quantitative Evaluation Of Actual Loss ReductionBenefits Of A Renewable Heavy DG DistributionNetwork, IEEE Transactions on Sustainable Energy, ISSN: 1949-3029

Modern distribution network architectures havegreatly changed due to the increasing proliferation of the networkwith power converters of renewable distributed generators(RDGs) and switching electronic loads. While these RDGs mayoffer benefits to the distribution network operator (DNO) interms of network loss reduction, the quantification of suchbenefits are usually investigated on the basis that harmonicsfrom the power converters are negligible. In this work, theelectrical power losses in a network with significant penetrationof photovoltaics (PVs) is assessed. The harmonics from the powerconditioners of the PVs and network background distortions havebeen taken into account in the analysis. Technical insights fromstudy of practical distribution networks are presented.

Anagnostou G, Pal BC, 2015, Impact of Overexcitation Limiters on the Power System Stability Margin Under Stressed Conditions, IEEE Transactions on Power Systems, Vol: 31, Pages: 2327-2337, ISSN: 1558-0679

This paper investigates the impact of the overexcitation limiters (OELs) on the stability margin of a power system which is operating under stressed conditions. Several OEL modeling approaches are presented and the effect of their action has been examined in model power systems. It is realized that, more often than not, OEL operating status goes undetected by existing dynamic security assessment tools commonly used in the industry. It is found that the identification and accurate representation of OELs lead to significantly different transient stability margins. Unscented Kalman filtering is used to detect the OEL activation events. In the context of stressed system operation, such quantitative assessment is very useful for system control. This understanding is further reinforced through detailed studies in two model power systems.
