Modelling And Performance Analysis of A Wind/Diesel Hybrid Power System

Domestic consumers in the remote places who are not connected by the main electrical grid network, hybrid systems such as wind/diesel generators have been considered as the most reliable, preferred and attractive alternative source of power supply. This paper presents the modeling and performance analysis of wind/diesel hybrid generating system. To regulate the frequency and voltage output of the wind generator, an AC-DC-AC scheme using SPWM technique is employed. The system is simulated for different wind speed and load conditions using EMTDC/PSCAD software

I. Introduction

In numerous remote and rural areas in the world, a noteworthy number of domestic consumers, farms and small businesses are not connected to a main electrical grid system. Since the remote areas are normally not connected to the grid supply, their usual method of electricity generation is diesel generating sets. These have the advantage of being able to deliver the required power whenever it is necessary. However, they also suffer from a number of drawbacks. Diesel generator engines are inherently noisy and expensive to run, especially for consumers in rural areas where fuel delivery costs may be high. In addition, small consumers always have a low load factor; this in turn reduces the overall efficiency and increases percentage maintenance costs.
