Addressing voltage sag contribution of an optimally sized Industrial Hybrid Power System: Using a multi-objective sizing framework considering cost and CO2 emission

This thesis titled "Addressing voltage sag contribution of an optimally sized Industrial Hybrid Power System" introduces a framework for sizing an industrial Hybrid Power System (HPS) to minimise Cost and CO2 emissions relative to connecting the industrial site directly to the grid with the help of a genetic algorithm, specifically NSGA-II. The...

Sizing of Hybrid Power Systems for Off-Grid Applications Using Airborne Wind Energy

The majority of remote locations not connected to the main electricity grid rely on diesel generators to provide electrical power. High fuel transportation costs and significant carbon emissions have motivated the development and installation of hybrid power systems using renewable energy such these locations. Because wind and solar energy is...

Hybrid Approach for the Modeling of Magnetic Force Excitations in Multipole Wind Turbine Generators Considering Air Gap Imperfections

Magnetic force excitations in the air gap of generators can lead to tonal noise emissions of direct-drive wind turbines. Besides the magnetic circuit design, the generator air gap topology has an impact on the excited vibration modes and their frequencies, respectively. For the model-based analysis of the excited force density waves, the spatial...

Novel particle swarm optimization algorithm based on president election: Applied to a renewable hybrid power system controller

Particle swarm optimization has been a popular and common met heuristic algorithm from its genesis time. However, some problems such as premature convergence, weak exploration ability and great number of iterations have been accompanied with the nature of this algorithm. Therefore, in this paper we proposed a novel classification for...

Wind Turbine Design for a Hybrid System: with the emphasis on generation complementarity

The global issue on global warming leads nations to reduce their carbon emission, and one way to do it is by decarbonising the power system and employing higher penetration of renewable energy technology. However, due to the variable nature of renewable energy, their integration to the power system poses challenges to the utilities and system...

Concept Design of Hybrid Crane Vessel

Heerema Marine Contractors operates large crane vessels, which are exploited for installation works in the offshore oil and gas industry. The benchmark power system of these crane vessels is diesel electric meaning that the main engines are driving alternators for generating electric power. But due to spiky power demand and strict redundancy...
