Hosting capacity quantification intends to provide the maximum aggregated capacity of distributed generation in low-voltage grids. Given the nonlinear nature of this problem, finding a solution in a simple and effective manner remains challenging. Moreover, previous studies have shown that solutions often display high disparities in hosting capacities among individual nodes, penalizing some and favoring others. Such disparities raise fairness concerns. In this paper, we propose a sequential linear optimization method to quantify the PV hosting capacity in low-voltage grids to address these issues. The linear formulation is achieved by using sensitivity matrices that approximate linear relations between changes in voltage and current magnitudes due to changes of PV capacities. To mitigate inaccuracies due to the linear formulation, multiple optimization problems are solved sequentially, updating the grid state at each stage with an AC power flow to realign the solution with the nonlinear problem. The performance of the proposed method is showcased using the CIGRE European low-voltage grid and by comparison with other established methods. To draw conclusions on a large and realistic dataset, the hosting capacities of 5196 low-voltage feeders from Austria are quantified under varying levels of disparity allowances.

Die Abschlussarbeit „Mich schreibend erkunden“ behandelt die Grundlagen und Methoden der Integrativen Poesie- und Bibliotherapie. Diese Form der Therapie berücksichtigt körperliche, emotionale, geistige und soziale Faktoren und nutzt kreative Medien wie Poesie und Literatur zur Förderung von persönlichem Wachstum und Heilung. Ein zentraler Bestandteil ist das Modell der „Fünf Säulen (des Supports) der Identität“, das verschiedene Dimensionen der Identität umfasst. Der geplante Workshop für Studierende der Rehabilitationspsychologie integriert diese Elemente.
