Formålet med denne veilederen er å styrke kompetansen om bruk av batterisystemer til spenningsstøtte i distribusjonsnett. Den gir teknisk og praktisk veiledning i vurdering, dimensjonering, spesifisering og styring av batterisystemer som alternativ til tradisjonell nettforsterkning. Veilederen er...

This report presents a techno-economic analysis of two heat pump application cases and a more general consideration of the integration of heat pumps compared to electric boiler. The heat pump systems of a distillation column and a dairy are assessed and benchmarked against a natural gas boiler and...

This report presents the concept and premises of a pilot plant for a megawatt (MW) charging station to be developed in Stord, Norway, under the MegaCharge project. The charging system comprises containerized charging modules designed for heavy-duty transport, integrating battery energy storage...

Literature review and test results from particulate matter measurements based on Norwegian Standard NS 3058-59 coupled with EC and OC analyses on an artificially aged woodstove....

The focus of the project "Methods of aggregation and disaggregation" are improved mathematical methods and computer tools for aggregation and disaggregation of hydro power systems in optimization models. These techniques are necessary for calculating the optimal utilisation of hydropower production...

This report deals with two types of network code requirements that apply to big photovoltaic installations and cannot be met with the use of inverters but require energy storage. The first of these requirements is frequency response. It prescribes how much the active power output of a...

Simultaneous gravimetric filter sampling of particulate matter in flue gas from chimney and diluted flue gas from dilution tunnel, on hot filter (≥ 70 ˚C) and on ambient filter (≤ 35 ˚C) respectively, to determine to which extent variables inherent to EN 13240 DIN+ and NS3058-59 affect the amount of...

A set of MATlab/Octave scripts have been developed, which output state matrices describing the linearized aerolastic dynamics of an offshore wind turbine. The aerodynamic model is based on momentum balance,and includes time-lag models for dynamic inflow, circulation lag, and dynamic stall. The...

I Norge kommer mer enn 90 % av distribuert produksjon fra småskala vannkraft. For distribusjonsnettselskap skaper integrering av slik produksjon en rekke utfordringer som krever navigering i et landskap bestående av mange aktører knyttet til både nett- og produksjonsutvikling; nettselskaper...

This work deals with evaluations of different possible cost-effective small-scale CHP solutions based on biomass for the Norwegian market. Many CHP technologies and systems exist today, and can easily be proposed as candidates for introduction and/or widespread use in the Norwegian market. However...

This report describes existing software tools for analysing operation and expansion of local energy systems and is written WP5 in the Research Centre on Zero Emission Neighbourhoods in Smart Cities (ZEN). WP5 in FME ZEN aims to develop and apply methodologies that identify the socio-economic optimal...

This report summarises the work performed in the RAKETT‐project. The project goal is to reduce the calculation time of the FanSi model. The FanSi model is a power market simulator for hydro dominated large‐scale power systems. The FanSi model formulates optimisation problems for the solution of the...

Political, regulatory and societal drivers and barriers for the realization of a meshed offshore grid between North Sea countries is here assessed. The Norwegian context is the point of departure, but with clear references to relevant processes at the European level. At the EU level there is an...

Particle concentration and size distribution, in addition to their composition, are essential information not only because of environmental and health concerns but also in order to be able to avoid deposition on heat transfer surfaces which may result in corrosion, fouling and subsequent efficiency...

Norsk iverksetting av EUs vannrammedirektiv skaper utfordringer i etablert forvaltningspraksis overfor regulerte vassdrag. Det tok syv år fra EU vedtok sitt vannrammedirektiv til det ble innført i norsk rett gjennom Vannforskriften, men da hadde man i mer enn 100 år hatt omfattende vannpolitiske...
