Renewables and Efficiency

Wind energy is re-shaping the global energy mix.

Life cycle assessment of an innovative multi-use offshore platform design. which unites wind and wave energy production in one platform. was executed in this study. By all means. the main contributor to all of the impact categories was manufacturing processes of MUP design. Due to having a design which requires …

In this paper a variable structure control based on a sliding mode control (SMC) of a doubly fed induction generator (DFIG) grid-connected wind energy conversion system. incorporating a maximum power point tracker (MPPT) for dynamic power control has been presented. This structure has been used for reference tracking of active …

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: …

An Edinburgh-based tidal energy firm will sit down with G7 ministers today to discuss the future of the offshore renewable energy sector.

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 …

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 …

This paper presents a 24 hour ahead microgrid power planning using the approach of unit commitment by dynamic programming. The studied system comprises twelve PVbased active generators with embedded storage and three micro gas turbines. Based on the prediction of the energy available from the PV generator. the storage availability. …
