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)
This paper presents a model predictive control (MPC) strategy for maximizing photo-voltaic (PV) selfconsumption in a household context exploiting the flexible demand of an electric water heater. The predictive controller uses a water heater model and forecast of the hot water consumption in order to predict the future temperature of the water and it manages(More)
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)
State estimation and control approaches in electric distribution grids rely on precise electric models that may be inaccurate. This work presents a novel method of estimating distribution line parameters using only root mean square voltage and power measurements under consideration of measurement tolerances, noise, and asynchronous timestamps. A measurement(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)
Electricity grids in many countries are facing the challenge of having to integrate an increasing amount of fluctuating power production from renewable resources. This creates a need for additional flexibility in the operation of the grid. In particular, the provision of power system services from distributed energy resources (DER) has been a strong focus(More)
This paper discusses and presents a simple temperature prediction strategy for the domestic refrigerator. The main idea is to predict the duration it takes to the cold chamber temperature to reach the thresholds according to the state of the compressor and to the last temperature measurements. The experiments are conducted at SYSLAB facility at DTU Risø(More)
