Czech electricity grid challenged by German wind

Abstract

Transmission systems in continental Europe are synchronously interconnected and represent one physical network over a very large area-from Portugal to Poland and from Denmark to Turkey. This interconnection allows electricity trading and mutual assistance among transmission system operators (TSOs). On the other hand, it may cause problems like system failures or instability spreading from one system to another. This interconnected system is now subject to the integration of large amounts of intermittent electric power and has to be technically upgraded and economically re-positioned [1]. © 2013 European Physical Society, EDP Sciences.
