This paper presents a contextual anomaly detection method and its use in the discovery of malicious voltage control actions in the low voltage distribution grid. The model-based anomaly detection uses an artificial neural network model to identify a distributed energy resource's behaviour under control. An intrusion detection system observes distributed(More)
—This paper presents two different aspects considering a co-simulation of smart grid scenarios. First considers representing the control strategy in a separate discrete event simulation developed in a multi-agent platform. This study investigates the design and implementation of such a simulator. Special attention is given to timing issues presenting time(More)
One of the challenging problems when it comes to electric energy distribution is electricity theft. Regardless of whether the deed is done on a large scale or only by a single consumer, it is a problem that generates losses and its detection is not always easy. One of the crucial factors making the issue of electricity theft still relevant is the common(More)
Increasing integration of distributed energy resources (DER) and available monitoring devices in the power distribution grid make system services provided by DERs possible and an integral part of distribution grid operation. Numerous publications have proposed various control solutions by utilizing different capabilities of DERs and regulating devices to(More)
Islands and rural areas can decrease their cost of energy by exploiting renewable energy as compared to diesel-only generation. Operation of such isolated micro-grids requires allocation of units for grid stability. Depending on the control strategy employed, the fluctuating renewable production leads to more stressed loading conditions of diesel(More)
