Abstract

Natural gas as source of energy is more desirable than other fosil fuel such as coal and oil because of environmental advantage. A big issue comes from the decision of new power plant, whether using natural gas or coal as source of energy. In area such as South East Asia, natural gas prices is higher than coal, hindering such uses. In order to make natural gas power plant more viable, some steps must be taken, such as optimization. This study will optimize the location of 5 power plant and pipeline route between 11 location and 2 natural gas sources, so the weighted length is minimum. Thus, a mathematical model developed to solve the problem, which is a Mixed Integer Nonlinear Problem (MINLP). Two step optimization used to obtain solution. The first step is used to obtaion optimal location and pipeline route, the second step is used to obtain optimal pipeline diameter and compressor configuration. A weighting element added to the pipeline length to accomodate the difference of pipeline diameter. Six scenarios are made in this study to give a different location and routing possibility regarding possible future scenarios.
