A frequency control method for isolated photovoltaic-diesel hybrid power system without smoothing renewable power variations
In this paper, a frequency control method is introduced for photovoltaic-diesel hybrid system by using a load estimator and an energy storage system. The proposed method is compared with an energy storage based conventional control method and with a fuzzy based frequency control method. Simulation results show that the proposed method is feasible to reduce the frequency deviations of the isolated ...

Minimum Total Harmonic Distortion on board Scandlines New Hybrid Ferries Berlin & Copenhagen - Case Study
In 2016, Scandlines inaugurated two new hybrid ferries for the Rostock-Gedser route. In order to improve the power quality, Scandlines installed active filters on board M/V Berlin and M/V Copenhagen. Before commissioning, Scandlines’ new hybrid ferries had a power quality of THDV 15%. In order for the ferries to go into operation, the power quality had to be reduced to below 8 percent THDV ...

The techno-economic and environmental aspects of a hybrid PV-diesel-battery power system for remote farm houses
In this study, the solar radiation data of Balikesir in Turkey are analysed to assess the techno-economic viability and environmental performance of a hybrid Photovoltaic (PV)-diesel-battery system to meet the load requirements of a typical remote farm house. Several aspects of the system are studied through the Cost of Energy (CoE), the operational hours of diesel generator, unmet load, excess ...

Inclusion of biodiesel and PV modules in a wind diesel hybrid system supplying electrical loads on a small farm
The growing interest in biofuels is a consequence of the need to reduce operating costs of energy systems and the need to reduce emissions of greenhouse gases. The same applies to PV modules, comprising a solution environmentally desirable for power generation. This paper presents a study on the inclusion of biodiesel and PV modules in a system already in operation on a small farm in southern ...

A novel stabilisation scheme for hybrid photovoltaic, fuel–cell and diesel gen–set utilisation system
The paper presents a novel FACTS–based modulated filter compensator scheme for a hybrid renewable photovoltaic–diesel–fuel cell common DC bus interface scheme. The proposed standalone photovoltaic–diesel–fuel system is fully interfaced using the common AC–DC collection bus topology. This allows for full decoupling of AC and DC type green source and ensures full flexibility in controlling the ...

Building New Industries and Creating New Jobs in a Plan B Economy
Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

Optimal sizing of a hybrid energy system for a semi-arid climate using an evolutionary algorithm
The use of a genetic algorithm (GA) for optimal sizing of an off-grid hybrid renewable energy system (HRES) is reported. As a pre-feasibility analysis and to determine the appropriate HRES type to be studied, wind energy potential and solar irradiation are first examined for the considered region (Tehran, Iran). These are inputs of the algorithm, and are assessed throughout a year utilising ...

A hybrid wind/solar/diesel stand alone system optimisation for remote areas in Algeria
While Algeria has an important potential of wind and solar energies, their share in the primary energy supply is relatively low compared to the fossil energy. In this paper, we propose to carry out a techno–economical study of a hybrid stand alone system in order to draw the attention to the feasibility of such systems. For this purpose, sites of Hassi–R'mel and Adrar have been ...

SGBI opinion article: shale gas
Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...
