WEB CRAWLING with Prof. Dr. Timm Teubner (TU Berlin)

Organiser: Prof. Dr. Timm Teubner (TU Berlin)  In this beginner’s guide to web crawling, we will cover the basics of how to automatically extract information from static and dynamic websites. The course will include a fair share of “hands on” work, in which we will write and run code ourselves (Java). If you plan to code along (highly recommended), please have a Java IDE...

Coronavirus and Care: How the Coronavirus Crisis Affected Fathers’ Involvement in Germany

Background: Some have hypothesized that the coronavirus crisis may result in a retraditionalization of behaviour. This paper examines this hypothesis by analyzing how the time fathers and mothers spent with their children changed during the first lockdown in the case of Germany.Methods: Data for this investigation come from the German Socio-Economic Panel. The outcome variable is the time spent on ...

Techno-Economic Criteria to Evaluate Power Flow Allocation Schemes

We develop novel quantitative techno-economic evaluation criteria for power flow allocation schemes. Such schemes assign which nodes are responsible for which proportion of power flows on a line in a meshed electricity transmission network. As this allocation is, as such, indeterminate, the literature has proposed a number of dedicated schemes. To better understand the implications of applying different ...

Ein höheres Inflationsziel für die EZB?

Erholung verliert an Fahrt – Wirtschaft und Politik weiter im Zeichen der Pandemie

Infolge der Maßnahmen zur Eindämmung der Corona-Pandemie ist die deutsche Wirtschaftsleistung in der ersten Jahreshälfte drastisch gesunken, vor allem in den Monaten März und April. Schon im Mai setzte eine kräftige Gegenbewegung ein, die sich in nahezu allen Branchen bis zum aktuellen Rand fortsetzte. Dieser Erholungsprozess dürfte an Fahrt verlieren. Die Institute erwarten daher nach einem Rückgang ...

An Open Tool for Creating Battery-Electric Vehicle Time Series from Empirical Data: emobpy

There is substantial research interest in how future fleets of battery-electric vehicles will interact with the power sector. To this end, various types of energy models depend on meaningful input parameters, in particular on time series of BEV motor electricity consumption, grid availability, and grid electricity demand. As the availability of such data is highly limited, we introduce the open-source ...

Prosumage of Solar Electricity: Tariff Design, Capacity Investments, and Power System Effects

We analyze how tariff design incentivizes households to invest in residential photovoltaic and battery systems, and explore selected power sector effects. To this end, we apply an open-source power system model featuring prosumage agents to German 2030 scenarios. Results show that lower feed-in tariffs substantially reduce investments in photovoltaics, yet optimal battery sizing and self-generation ...

DIETERpy: a Python framework for The Dispatch and Investment Evaluation Tool with Endogenous Renewables

DIETER is an open-source power sector model designed to analyze future settings with very high shares of variable renewable energy sources. It minimizes overall system costs, including fixed and variable costs of various generation, storage and sector coupling options. Here we introduce DIETERpy that builds on the existing model version, written in the General Algebraic Modeling System (GAMS), and ...
