Facing current and future developments of the energy system, including the integration of large numbers of renewable energy sources and electric vehicles, live monitoring and control becomes essential for stable operation of the power grid. This transition to a Smart Grid requires coupling the power system with a reliable and real-time capable communication infrastructure. In response to this demand,...
Changing dynamics of power systems caused by the large-scale penetration of renewable energy sources and a different behaviour of future distribution networks increase the risk of large-scale blackouts due to voltage collapse, especially in case of unforeseen network conditions (e.g., (N-k)-cases). To enable a both secure and efficient power supply, novel emergency control systems are required that...
Increasing uncertainties in power system operation require novel approaches for utilizing operational flexibility to enable a both secure and efficient power supply. This paper presents a real-time coordination approach for adaptive redispatch of generation and load in case of overloads in the electrical transmission network. For this, a previously developed multi-agent system for coordinating power...
Power flow simulators are indispensible when simulating and assessing future energy system scenarios potentially comprising vast numbers of actors, devices, markets, environmental phenomena etc. While open source power flow simulators are an appealing choice – as they come free of charge – commercially available power flow simulation and optimization suites have the clear benefit of being well established...
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...
