Optimal Pathways for Power Supply
- 84 Downloads
The second component of the integrated modeling framework is evaluating the optimal energy supply pathways for a particular region for a particular time given multiple constraints on resources, capital, emissions, etc. Various methods can be used to estimate energy demand. One such method used in this modeling framework is an input-output analysis that estimates economy-wide energy demand. This is discussed in Chap. 5. The next step after estimating demand is to evaluate ways in which this demand can be met. This includes estimating the appropriate fuel mix to satisfy energy needs. In this chapter a model is presented for the power sector that takes into consideration some of the key characteristics of the sector and fuel technologies. The objective is to arrive at estimates for the optimum fuel supply pathway for the power sector for a given demand. This chapter includes a detailed description of the power sector model built using the GAMS (General Algebraic Modeling System) platform and a few scenarios constructed for the purpose of illustrating the working of the model.
