Applicability of a modular powerplant with alternative fuels: A case study to determine the impact on ships operation capabilities and power plant performance, when using a modular power plant for a 2999 gross tonnage general cargo concept ship

This paper examines a case study to determine the effects on system performance of the power plant and ship operational capabilities, this case is a ship designed by the company DEKC. It is a small general cargo vessel of 2999 GrT (Gross Tonnage) called the Future Trader. The ship design is finished and the ship will be equipped with a modular...

Ancillary Services Market Design in Distribution Networks: Review and Identification of Barriers

The high proliferation of converter-dominated Distributed Renewable Energy Sources (DRESs) at the distribution grid level has gradually replaced the conventional synchronous generators (SGs) of the transmission system, resulting in emerging stability and security challenges. The inherent characteristics of the SGs are currently used for...

Comparison of the solid oxide fuel cell system for micro CHP using natural gas with a system using a mixture of natural gas and hydrogen

Solid oxide fuel cell systems for combined heat and power production (SOFC μCHP) fueled by natural gas are attractive because of their high electrical and total efficiency even at small scale. The development of a hydrogen economy will increase the availability of distributed hydrogen as a pure gas. Alternatively, hydrogen may be blended with...

Energy Management in Smart Cities

Models and simulators have been widely used in urban contexts for many decades. The drawback of most current models is that they are normally designed for specific objectives, so the elements considered are limited and they do not take into account the potential synergies between related systems. The necessity of a framework to model complex...

Energy contribution of OFMSW (Organic Fraction of Municipal Solid Waste) to energy-environmental sustainability in urban areas at small scale

Urban waste management is one of the most challenging issues in energy planning of medium and large cities. In addition to the traditional landfill method, many studies are investigating energy harvesting from waste, not as a panacea but as a foreseeable solution. Thermo-chemical conversion to biogas, or even bio-methane under certain...

Agent-Based Modelling for Security Risk Assessment

Security Risk Assessment is commonly performed by using traditional methods based on linear probabilistic tools and informal expert judgements. These methods lack the capability to take the inherent dynamic and intelligent nature of attackers into account. To partially address the limitations, researchers applied game theory to study security...

Small-signal modelling and stability analysis of a traditional generation unit and a virtual synchronous machine in grid-connected operation

The virtual synchronous machine (VSM) concept has emerged as an approach to provide flexible distributed control of power electronic converters interfacing distributed energy resources with the grid. It supports power system operation by providing ancillary services, and facilitates a seamless transition between grid-connected and islanded...

Design of a power electronic assisted series compensator for grid voltage regulation

In recent years, high penetration of distributed generation (DG) driven by PV panels and heavy load insertion in the distribution network has led to frequent voltage fluctuations in the form of undervoltage and overvoltage. Voltage control using traditional voltage regulators are unable to cope with this situation as frequent tap changes reduce...
