Control and Coordination of multiple BESS in a Low Voltage Distribution Network

The rapidly growing number of renewable energy technologies has started changing the infrastructure of the conventional energy sector, which was based on one-directional power flow. Bidirectional flows are created in the network with the integration of renewable technologies. The electricity network and system operators face many new challenges...

Solar-assisted ground-source heat pump solutions for Dutch terraced houses: Investigation and modelling of SAGSHP technology as an alternative to traditional gas heating systems

In the last decades, the excessive increase in average global temperature related to a massive rise in greenhouse gas emissions showed the world how the fossil fuel society we live in today is drastically modifying and destroying the world we live in and is turning it in an un-habitable planet. Scientist all over the world made it clear that if...

Extended semi-analytical model of bipolar hybrid stepper motor

The aim of this graduation thesis is to present a bipolar stepper motor semi-analytical model and compare its simulated motor dynamics. Stepper motor modeling has been successfully used to simulate motor performance and dynamics, yet, each modeling method holds advantages and disadvantages toward one another. In this thesis, the analytical...

Power-to-gas efficiency of a hydrogen back-up system governed by interruptible sources and services

Fossil fuel based energy systems are the main contributor to global warming. As new regulations come into place, a transition towards a more sustainable energy system must be realised. Hydrogen usage is regarded as the key enabler of such systems. The heart of these hydrogen-based energy systems (HESs) is the hydrogen back-up system (HBS) which...

Daytime radiative cooling: A new passive cooling method for dwellings in the Mediterranean island of Cyprus

Daytime radiative cooling (DRC) is a very novel passive cooling method for buildings that utilises the recent technological advance in wavelength selective-emittance material research and takes advantage of a transparency window that exists in the atmosphere between 8 and 13 μm. Application of DRC in locations where warm weather prevails for...
