As the power system is developing, the need for new cost-efficient grid solutions is increasing. A battery energy storage system (BESS) can prove to be a technically and economically feasible alternative to a grid reinforcement. This paper presents a techno-economic analysis of a BESS used to...
The electrification of the energy sector challenges the conventional methods to meet the increased load demand. The rapid increase of electric vehicles and the desire for shorter charging time at fast charging stations (FCS) contributes to higher power peaks in local distribution grids. This may...
This paper proposes a model to include investments in demand flexibility into traditional transmission expansion problems under uncertainty. To do so, a dynamic power flow model is proposed. The model is solved via applying a value function approximation in form of a neural network on the...
Diatomaceous earth (DE) is a naturally occurring silica source constituted by fossilized remains of diatoms, a type of hard-shelled algae, which exhibits a complex hierarchically nanostructured porous silica network. In this work, we analyze the positive effects of reducing DE SiO2 particles to the...
Sintef er med i EU-prosjektet Flexplan, der ulike aktører skal utvikle modeller som gjør det mulig å vurdere fleksibilitet fra ulike kunder i stedet for fysiske nett-oppgraderinger. Når alt skal elektrifiseres, slik at flere har elbil, befolkningen vokser, og nettet eldes vil vi trenge investeringer...
This study investigates the impact of operational fluctuations and uncertainties on the design and expected cost of ship-based CO2 transport. The model analysis is based on a two-stage stochastic investment model for a single-source single-sink CCS value chain with a ship-based transport system. The...
Declining equivalent inertia caused by the massive integration of converter-based technologies can increase the risk of stability problems in the future power system. Control of HVDC systems as Virtual Synchronous Machines (VSMs) for providing emulated inertia is a promising countermeasure against...
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, but to achieve customers' involvement, knowledge about their willingness...
