INTEGRATED RENEWABLE ENERGY MANAGEMENT SYSTEM FOR SUSTAINABLE DEVELOPMENT

The focus of this study is to look into the possibility of integrating a solar based system
into an existing combined cycle power plant. This new system named as Integrating Solar
Combined Cycle Power Plant (ISCCPP) consist 6 main parts which are Gas Turbine
(GT), Heat Recovery Steam Generator (HRSG), Steam Turbine (ST), Condenser,
Feedwater Tank and Solar Field. The solar energy is the alternative to overcome the
crucial problem of the fossil fuel volatility, depletion and increasing of prices. In Eight
Malaysia Plan (2000-2005), the expansion in the installed capacity of electricity from
14,291MW to 19,217MW. In year 2010, the installed capacity hike into 25,258MW
(Appendix A). Besides it's risky to rely on the single and depleting energy sources.
Therefore, the plan and proper management has to be done to ensure the continuously of
producing power for sustainable human development. This project is to study the
combined cycle power plant equations and merge with the solar radiation from the sun. It
is translated into Visual Basic.NET in order to simulate the Combined Cycle Power Plant
(CCPP) and Integrated Solar Combined Cycle Power Plant (ISCCPP) and make
comparison. The ISCCPP consumes less of natural gas in producing power. Based on the
current CCPP type, Lumut Power Plant, the maximum efficiency is 54%. Through the
simulation and implementation of solar field by adding the local global solar radiation, at
full load, this new system ISCCPP can produce more 59MW of electricity than CCPP. By
doing this project work, it was revealed that the solar radiation in Malaysia is still low
and only the 6 hours (10am-3pm) can be considered as the peak solar radiation which is
very useful. Besides, the cloudy season can interrupt the capture amount of solar
radiation by solar absorber. So the deep research has to be done to choose the suitable
place for this system. Besides, with the hi-technology today this problem can be
overcome.
