Die vorliegende Arbeit untersucht den Einfluss verschiedener Detailgrade auf die Ergebnisqualität von Netzstudien. Dabei werden die Herausforderungen der Netzplanung im Zusammenhang mit dem raschen Ausbau erneuerbarer Energien und der Elektrifizierung von Wärme- und Mobilitätssektoren angesprochen. Es wird eine zweistufige Methodik angewendet, die...
In several countries, PV capacity has exceeded the country's minimum load. Unlimited feed-in at all times is therefore becoming less and less possible. Curtailment is not a goal. It is a method for increasing the utilization of power grids without exceeding their physical limits.
The ratio of annual energy yield to peak power is smaller for PV sy...
![State‐of‐the‐art optimal power flow with AC distribution factors [24].](publication/374901591/figure/fig1/AS:11431281209627453@1701807899326/State-of-the-art-optimal-power-flow-with-AC-distribution-factors-24_Q320.jpg)
A novel method is introduced to determine cost‐optimized active power curtailment (APC) of renewable energy sources (RES) considering weather‐dependent dynamic line rating (DLR). A new formulation of the security‐constrained optimal power flow (SC‐OPF) is developed and applied in a case study. The reduction of the required preventive APC in the (N-...
We introduce a novel method to determine cost-optimized Active Power Curtailment (APC) of Renewable Energy Sources (RES) considering weather dependent Dynamic Line Rating (DLR). A new formulation of the Security-Constrained Optimal Power Flow (SC-OPF) is developed and applied in a case study. We demonstrate the reduction of the required preventive...
The increased penetration of renewable energy sources in German energy supply structures requires reinforcing and expanding of electrical grids. Grid planning requires complex calculations to ensure demand-driven, efficient, and environmentally friendly operation of the electrical grids. In order to accelerate the necessary expansion of renewable e...
Seit der Neuerung des Energiewirtschaftsgesetzes 2016 [1] ist die Spitzenkappung ein neues Planungsinstrument für Netzbetreiber. Die planerische Annahme der Abregelung von 3 % der Jahresenergie einer Erneuerbare-Energien-Anlage (EEA) ist seitdem gesetzlich verankert. Auf EU-Ebene ist ebenfalls ein entsprechendes Gesetz auf den Weg gebracht worden,...
