Methodological Approaches for the Estimation of a Capacity Credit of a Grid-connected Photovoltaic Electricity Generation

Abstract

Renewable energy sources are getting more and more important. The authors present and discuss different methodological approaches for the estimation of a capacity credit of a grid connected photovoltaic power generation system. First only the solar energy supply is considered. Then a mixed conventional-renewable power plant system is investigated. Afterwards the interrelation between the demand-side behaviour of the electricity consumption and the photovoltaic power generation is analyzed. Later on the given solar energy supply during annual peak load periods observed during the last 25 years is investigated
