Abstract:The expansion of renewable energies is progressing strongly. The influence on the power supply networks by the variability of the infeed must be met with new concepts. In this paper, we investigate the possibilities of integrating microgrids as a cooperating unit in the power supply network to support further expansion of renewable energy sources (RES) power plants. In this paper, a differentiation of microgrids from similar network structures is established, and a classification of proposed groups is made. Then, after the description of the simulation of the components in a microgrid, with practical advice, an example model is shown, which aids the dimensioning of the components within a microgrid to achieve a specified goal.

Abstract. In this paper spherical irradiation measurements are exploited and compared to power output in order to assess PV system generation potential. Not the spherical irradiation as a sum is measured, but irradiation referred to a specific solid angle. This approach enhances generation forecasting for predefined panel orientations within urban areas. In urbanised regions sophisticated shadowing and reflexion patterns result generally in complicated generation predictions.
