This paper deals with an enhanced modulator concept for the Modular Multilevel Converter. Based on an overview on existing concepts including module sorting algorithms and measurement results from a hardware-setup in laboratory, a new concept is developed. Measurement results of the implemented new algorithm for module selection and capacitor energy balancing in various operating points of the converter...
The first Electric Storage System connected to the MV Italian distribution network has been activated during 2012 by Enel Distribuzione. The installation is based on a lithium-ion battery solution by Siemens AG; the rated power is 1 MVA and the energy capacity is 0.5 MWh. This paper presents the results of site acceptance tests (evaluation of the efficiency, consumption of the auxiliary services etc...
