Tutorial Session
Optimization of Renewable Energy-Based Distributed Generation
Power Systems
Associate Professor Ahmad Zahedi, James Cook University,
Queensland, Australia
Synopsis
Since the global warming and climate change are recognized as
real concerns, the development of science-based alternative
energies that are sustainable, reliable, and more efficient is
now the national priority of many countries around the world.
Currently electricity is generated in central power stations and
then is brought to customer’s distribution network by using
expensive high voltage facilities such as transmission lines and
power transformers. It is expected that in the future small to
medium scale distributed generation (DG) power systems using
renewable and non-renewable energy technologies will gradually
be replacing the current central power systems. This is because
the DG systems are located close to the load being served,
therefore no need for expensive high voltage equipments and
facilities.
Distributed generation (DG) is the use of power generation
technologies located close to the load. In most of its
applications, DG can reduce cost, improve system’s reliability,
reduce greenhouse gas emissions, and can increase grid security.
Distributed generation covers a wide range of technologies,
renewable & non-renewable, such as solar photovoltaic, wind,
fuel cell, combined gas turbine, and etc.
The objective of this tutorial session is firstly to review the
technical and economical aspects of distributed generation
technologies. Secondly, discuss about the important factor need
to be considered in designing a DG power system. And finally, to
present the results of a computer simulation developed to
predict performance of a DG power system.
