Item Las nuevas redes eléctricas inteligentes, su medida y gestión de la demanda(2011-06) Madina-Doñabeitia, Carlos; Arechalde-Ugarteche, Ibón; POWER SYSTEMS; Tecnalia Research & InnovationIncreasing electric energy demand and growing contribution from renewable energy sources to energy supply require a change in the operation of electricity networks. Electric grid must evolve from the traditional role of electricity carrier to becoming an infrastructure which not only allows the flux of electrons, but also the flux of information between the different participants in the electricity system, i.e., becoming a smart grid. In order to fully develop smart grids, household consumers' demand must be softened, so that its flexibility can be used for improving electric system stability. Nevertheless, residential consumers will not be able to manage their electricity demand, unless they can access the required infrastructure. This paper presents the characteristics of PRIME technology, both for allowing the required information exchange for smart grid evolution, and for giving household consumers access to demand side management services.Item Performance of PLC communications in frequency bands from 150 kHz to 500 kHz(Institute of Electrical and Electronics Engineers Inc., 2017-04-11) Arechalde, Ibon; Castro, Marta; Garcia-Borreguero, Ibone; Sendín, Alberto; Urrutia, Iker; Fernandez, Ainara; Tecnalia Research & Innovation; Generales; Datos y ProtocolosOne of the most common communications technologies being used as the media to access the meters in Smart Metering deployments is Narrowband Power Line Communications (NB-PLC), mainly in Europe but also in other places. Most of the systems available in the market under NB-PLC are extending the frequency bands used in order to increase their bandwidth and avoid interferences from other devices in the network. This paper presents results obtained in real-field tests performed by Iberdrola and Tecnalia in an urban LV distribution network representative of this kind of installations in Europe. The objective of the tests is to verify the performance of a NB-PLC technology using frequency bands from 150 kHz to 500 kHz. The tests have been developed in several points of the same LV distribution network, checking point to point connections among them. Apart from the performance of the different links, the noise levels measured at the reception points have been also analyzed.
