Due to the increasing exchanges of electricity in Europe, advanced Capacity Allocation and Congestion Management (CACM) methods, such as zonal flow-based market coupling (FBMC), have been developed. For instance, the implementation of the FBMC method is accompanied by high computational effort due to the large number of possible Critical-Branch-Critical-Outage (CBCO) combinations, especially in large-scale...
The coupling of electricity markets and the increasing feed-in of renewable energy sources (RES) cause a rising number of congestions in the European transmission network. In order to ensure a secure network operation suitable measures for resolving these congestions need to be found. In this context, a methodology for analyzing congestions in transmission systems is presented in this paper. The methodology...
Electrical energy transmission systems are facing major challenges like the continuing integration of renewable energy sources and the coupling of the European electricity markets. Investigating the impact of such developments on the transmission systems by network analysis involves a high computional effort due to the system size. Thus, complex analyses like network extension planning are difficult...
Due to the increasing feed-in of Renewable Energy Sources (RES) and the coupling of electricity markets the European energy system faces major changes. To investigate the impact of these developments on the European transmission system in particular, a network model in combination with nodal load and generation time series is required. With the Model of International Energy Systems (MILES), a combined...
The integration of measurement equipment and actuators in distribution networks enables concepts of autonomous and automated network operation. The trend of adding network automation is motivated by the increasing integration of decentralized generation units on the distribution level. This development leads to continuously changing grid behavior as there are times when load or feed-in dominate. Therefore...
The increasing feed-in of Renewable Energy Sources (RES) and the coupling of electricity markets fundamentally change the European energy system. To investigate the impact of these developments, models are necessary which provide regionally disaggregated load and generation time series as an estimate of future system states. With the Model of International Energy Systems (MILES), this paper presents...
The energy transition, which leads to shutdowns of conventional power plants with simultaneous expansion of renewable energy power plants, causes a strong change in the utilization of the transmission grid. It has to handle larger transport tasks, whereby the reactive power demand increases. At the same time fewer conventional power plants are available to balance the reactive power demand of the...
Managing uncertainties becomes a major challenge in power systems with a high penetration of volatile generation and load. On the contrary, the controllability of the transmission system increases due to the evolution of a smart grid and more flexible technologies. In this paper a methodology for analyzing the impact of uncertainties and operational flexibility in the context of different market coupling...
This paper proposes a forecast-based network reconfiguration algorithm and its application to a distribution network. Altering loads and generation may cause overloads while operating the network at the static topology configuration. By using forecast-based nodal power time series a suitable switching strategy is generated. In a second step the amount of switching actions is to be reduced. The generated...
The increasing number of distributed energy resources on distribution level causes several problems in distribution grids like overloads and voltage range deviations. To resolve these problems and to avoid a necessary cost intensive network expansion, smart grid solutions can be applied. However, the lack of measurement data on the distribution level means that there is no full knowledge of the current...
