    We present a stochastic modelling approach to describe the dynamics of hourly electricity prices. The suggested methodology is a stepwise combination of several mathematical operations to adequately characterize the distribution of electricity spot prices. The basic idea is to analyze day-ahead prices as panel of 24 cross-sectional hours and to identify principal components of hourly prices to account for the cross correlation between hours. Moreover, non-normality of residuals is addressed by performing a normal quantile transformation and specifying appropriate stochastic processes for time series before fit. We highlight the importance of adequate distributional forecasts and present a framework to evaluate the distribution forecast accuracy. The application for German electricity prices 2015 reveal that: (i) An autoregressive specification of the stochastic component delivers the best distribution but not always the best point forecasting results. (ii) Only a complete evaluation of point, interval and density forecast, including formal statistical tests, can ensure a correct model choice.

  • Trepper, K.; Weber, C.; Deilen, C.: Vergleich von Redispatch-Vergütungsmodellen und Entwicklung eines nachträglich zonalen Modells für ein effizienteres Engpassmanagement in Deutschland. Essen CitationDetails

    Traditionell basiert das Engpassmanagement in Deutschland auf bilateralen Verträgen. Jedoch setzt eine Vergütung basierend auf bilateralen Verträgen nur begrenzt Anreize. So haben die Kraftwerksbetreiber keine Anreize, ihre Grenzkosten offenzulegen. Zudem ist die Teilnahme am Redispatch nicht verpflichtend, wodurch ein mögliches hohes Potential nicht genutzt wird. Aus diesen Gründen ist es wichtig, das Engpassmanagement in Deutschland neu zu gestaltet. In diesem Artikel werden daher verschiedene Redispatch-Vergütungsmodelle, wie sie in der Literatur diskutiert werden (Inderst, Wambach (2007), Hakvoort et al. (2009)), miteinander verglichen und hinsichtlich ihrer Anreize für Produzenten, Übertragungsnetzbetreiber und Konsumenten bewertet. Des Weiteren wird ein nachträglich zonales Modell als eine kurzfristige, effiziente Engpassmanagementmethode entwickelt. Der Fokus dieser Analyse liegt auf Deutschland als eines der größten Strommärkte in Europa.
