An Evaluation of the Optimal Generation Mix for Controlling Carbon Dioxide Emissions.

This Paper presents an efficient computational algorithm for selecting the optimal generation mix considering CO 2 emission. To demonstrate the effectiveness and feasibility of the proposed method, a fundamental study of the evaluation of the optimal generation mix for controlling CO2 emissions is indicated, Futhermore, by using parametric analysis which considers load characteristics as parameters, a general trend for the optimal generation mix which is affected by controlling CO2 can be derived. The proposed method is based on an optimization method know as simulated. In the method, solution in a generation mix problems are equivalent to states of physical system, and the cost of a solution is equivalent to a state. The proposed method can easily accommodate not only CO2 emission but also many practical constrains of generation expansion planning, such interger solutions of unit capacities, condition of existing units, and so on. Case studies various annual load patterns (combinations of annual factors and the shapes of annual load duration curve) are presented and discussed. Consequently, a general trent for selecting generation technologies that should be added to a power system is derived, i.e., a useful guideline for studying generation expansion planning under controlling CO2 emission can be provided.
