Measurement-based frequency-dependent model of a HVDC transformer for electromagnetic transient studies
(Peer reviewed; Journal article, 2020)A wide-band, frequency-dependent five-terminal model is developed that represents one HVDC transformer unit in the French-English IFA2000 HVDC interconnection. Three such interconnected 1-ph units constitute one 3-ph ... -
A proposed methodology for modelling the combined load of electric roads and households for long-term grid planning
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)The number of electric vehicles (EV) is increasing rapidly, and it is not yet sure how the grid infrastructure will be built, and how this will affect the power system. One option for charging EVs is a dynamic wireless ... -
A Stochastic MPEC Approach for Grid Tariff Design with Demand-Side Flexibility
(Peer reviewed; Journal article, 2020)As the end-users increasingly can provide fexibility to the power system, it is important to consider how this fexibility can be activated as a resource for the grid. Electricity network tarifs is one option that can be ... -
Pressure-Dependent Propagation of Streamers under Step Voltage in a long Point-Plane Gap in Transformer Oil
(Peer reviewed; Journal article, 2020)The effect of pressure on positive and negative streamer propagation in a mineral transformer oil is studied in an 80 mm point-plane gap under step voltage. Increased pressure causes reduced stopping length for non-breakdown ... -
Status of waste-to-energy in Germany, Part I ? Waste treatment facilities
(Peer reviewed; Journal article, 2020)This study gives a detailed overview over the German waste-to-energy sector in 2015. The aim is to quantify the available treatment capacities and the energetic potential of waste in Germany. The work is based on an extensive ... -
The dynamics of solar prosuming: Exploring interconnections between actor groups in Norway
(Peer reviewed; Journal article, 2020)Solar prosuming is an emerging phenomenon in which many actor groups are involved in shaping new solutions. Here we study national policymakers, relevant stakeholders such as grid companies, and the prosumers themselves – ... -
Assessment of flexibility in different ancillary services for the power system
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)To handle the changing power system and enable the energy transformation, several actions are needed, where the increase of digitalization, automation and more substantial production variability implies a need for flexibility. ... -
Impact on hydropower plant income from participating in reserve capacity markets
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)The aim of this work is to simulate prices in the markets for spot and spinning reserve capacity in the Nordic region. We consider four selected seasonal weeks using a model framework for multi-market price forecasting in ... -
Exploring household's flexibility of smart shifting atomic loads to improve power grid operation and cost efficiency
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)This paper explores the possibilities of shifting certain household consumer-based loads in time, to reduce unnecessary load peaks to the grid which again can cause challenges for Distribution System Operators (DSOs). ... -
Combining Machine Learning and Optimization for Efficient Price Forecasting
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)We present a framework based on machine learning for reducing the problem size of a short-term hydrothermal scheduling optimization model applied for price forecasting. The general idea is to reduce the optimization problem ... -
Site approval test of heat pump drying: Design, installation, and test run with of demonstration unit
(SINTEF Rapport;2020:00971, Research report, 2020)The objective of the SusOrgPlus project is to prototype and validate the concept of heat pump drying at TRL 6 in close cooperation with the supply industry. The demonstration unit shall be used to maximise energy efficiency ... -
Flexibility potential at Norwegian households - customer evaluations and system benefits
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)The peak load in electricity consumption is increasing among household customers, resulting in reduced utilization time of the distribution grid. Demand side flexibility can be a cost-efficient alternative to grid investments, ... -
Household customers' assessment to capacity based distribution grid tariff
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)This paper presents the status of regulation related to distribution grid tariffs in Norway, and household customers’ assessment of having such a tariff scheme. The paper is presenting results from a Norwegian pilot where ... -
The importance of thermodynamic insight in Work and Heat Exchange Network Design
(Peer reviewed; Journal article, 2020)Work and Heat Exchange Network (WHEN) design has been an emerging topic in the area of Process Synthesis and has attracted increasing research interest in the past few years. Not only temperature changes but also pressure ... -
A detailed review on CO2 two-phase ejector flow modeling
(Peer reviewed; Journal article, 2020)Ejector-equipped vapor-compression systems for refrigeration and cooling, relying solely on (R744) as a natural working fluid, are perceived to be an eco-friendly and highly efficient solution for many applications. However, ... -
Evaluating Cost Trade-Offs between Hydropower and Fish Passage Mitigation
(Peer reviewed; Journal article, 2020)To promote the sustainable management of hydropower, decision makers require information about cost trade-offs between the restoration of fish passage and hydropower production. We provide a systematic overview of the ... -
