Biodiesel is a promising non-toxic and biodegradable alternative fuel used in the transport sector. Nevertheless. the higher viscosity and density of biodiesel poses some acute problems when it is used it in unmodified engine. Taking this into consideration. this study has been focused towards two objectives. The first objective is …

In this paper. the efficiency optimization of an axial flux permanent-magnet synchronous generator with concentrated pole windings is examined for a 3.6 kW 2000 rpm combined heat and power application. Because the efficiency of the machine is important. specific measures are taken in order to reduce losses in the machine: …

The increasing development of large-scale offshore wind farms around the world has caused many new technical and economic challenges to emerge. The capital cost of the electrical network that supports a large offshore wind farm constitutes a significant proportion of the total cost of the wind farm. Thus. finding the …

Modern power systems require increased intelligence and flexibility in the control and optimization to ensure the capability of maintaining a generation-load balance. following serious disturbances. This issue is becoming more significant today due to the increasing number of microgrids (MGs). The MGs mostly use renewable energies in electrical power production …

Randomness of wind speed around a short-durationstable mean value is commonly referred to as short duration wind variation. This paper investigates the effect of substantial windbased capacity inclusion on optimal load dispatch. with the source wind susceptible to short duration variations. Analytical formulation of the economic load dispatch (ELD) problem …

The private power producers are increasing rapidly to meet rising load demand in domestic. commercial. and industrial sectors. In this scenario. the distributed generation systems (DGs) play an important role over fossil fuel generation. Among different distributed generation technologies such as fuel cell. wind power. and solar. the fuel-cell-based distributed …

In this study the geometrical optimization of monolithically integrated solar cells into serially connected solar modules is reported. Based on the experimental determination of electrodes0 sheet and intermittent contact resistances. the overall series resistance of individual solar cells and interconnected solar modules is calculated. Taking a constant photocurrent generation density …
