WIND AS RENEWABLE SOURCE OF ENERGY

Simulation Techniques for Modelling Renewable Conversion Systems

Abstract

In this study simulation technique for modelling renewable conversion system would be discussed. This paper begins with an introduction in which it emphasis has been given to the renewable sources of energy throughout the world. Commercial software and their importance in context of wind power have also been discussed along with importance of wind as renewable source of energy and technique for modelling wind power. The study concluded that wind is one of the best and cheap sources of renewable energy and by the usage of commercial software and other optimization techniques the sustainable power generation from wind could be maximize.Table of Contents

Simulation Techniques for Modelling Renewable Conversion Systems

Introduction

With the speedy growth of the global economy, energy requirements have increased remarkably, especially in emergent countries. The realization that fossil fuel resources required for the generation of energy are becoming scarce and that climate change is related to carbon emissions to the atmosphere has increased interest in energy saving and environmental protection (Vine, Pp. 49-63). The first strategy to reduce dependence on fossil resources is based on reducing energy consumption by applying energy savings programs focused on energy demand reduction and energy efficiency in industrial (Cai, Pp. 721-35) and domestic (Vine, Pp. 49-63) fields spheres.

A second strategy to achieve this goal consists of using renewable energy sources, not only for large-scale energy production, but also for stand-alone systems (Zangeneh, Pp. 2765-73). Lund et al. analyzed strategies for a sustainable development of renewable energy taking into account three main technological amendments: efficiency enhancement in producing energy, replacing fossil fuels with different sources of renewable energy and energy savings on the demand side. Renewable energy technologies are known to be noncompetitive than customary conversion systems of electrical energy, mainly because of their intermittency and the comparatively high cost of maintenance. However, renewable energy sources have several advantages, such as the reduction in dependence on fossil fuel resources and the reduction in carbon emissions to the atmosphere. Furthermore, renewable energies avoid the safety problems derived from atomic power, which is why, from the social viewpoint, it has become more suitable to adopt renewable energy power stations. An important decision for governments and businesses is whether or not to establish renewable energy systems in a given place, and to decide which renewable energy source or combination of sources is the best choice. (Hernández-Escobedo et al. Pp. 2830-40)

Several authors have evaluated the main renewable energy technologies taking into account sustainability indicators, such as (Alvarez-Valdes et al, Pp. 1153-70) who compared wind power, hydropower, photo- voltaic and geothermal energy taking into account the emission of greenhouse gases throughout the full life cycle of the technology, the cost of produced electricity, effectiveness of energy conversion, water consumption, social impacts, land requirements and accessibility of renewable sources.
