A method for the quantitative assesment of reliability of Smart Grids

This paper describes a method for the quantitative assessment of reliability of Smart Grids that evaluates the combined behaviour of the distribution grid, the telecom infrastructure and the control functions. It is based on a method that has already been used successfully for large and complex telecommunication networks. We expanded this method to allow the inclusion of distribution grid components and energy flow calculations. This method aims to be a valuable tool during the design and planning phases of Smart Grids: i.e. for comparing the expected reliability of design alternatives and for identifying risk areas, weaknesses and their impact on the reliability.
