This paper presents a single-phase Virtual Synchronous Machine (VSM) and its possible application for providing Vehicle-to-Grid (V2G) services from domestic battery chargers of Electric Vehicles (EVs). In a VSM, the power converter is controlled to emulate the inertia and the damping effect of a...

Industry is responsible for about 25-30 % of the global primary energy demand (Elmegaard, Zühlsdorf et al. 2017), and around two thirds of this is used for heating and cooling (Elmegaard, Zühlsdorf et al. 2017). Several recent innovations can improve the thermal energy efficiency and enable smart...

Organic production is often regarded as more sustainable compared with conventional production. However, in most cases only the primary production step on farm is considered while the postharvest processing is neglected. Even though the sector strives towards sustainable processing, the techniques...

The expected abolishment of SF₆-gas in medium voltage switchgear has prompted a search for replacements for the switch types that depend on SF₆ to obtain the required capability, reliability, compactness and cost. Ablation of polymers can enhance the arc-quenching capabilities in certain electrical...

Due to the enormous carbon footprint of food retail stores the interest in natural working fluids, such as propane (R290) and CO₂ (R744), has recently intensified in the commercial refrigeration sector. In this theoretical investigation the performance of various technologies employing low-global...
