Optimum Replacement Policies of Conventional Energy Sources by Clean Ones Subject to Current Electricity Demand
並列摘要
Developing optimum decision policy for gradual replacement of conventional energy sources by clean ones is an important field of current research and the main concern of this article. Eight main energy sources are considered and the decision policies are formulated with the objective of minimizing the implementation and environmental costs while meeting the electricity demand during the entire plan period. The selected energy sources are Coal, Petroleum, Natural Gas, Hydropower, Wind, Solar, Geothermal and Biomass. A nonlinear dynamic Lotka‐Volterra model, first introduced in Miah, Ahmed and Chowdhury and later extended in Parsa, Ahmed and Yagoub, is used for modeling the dynamic changes in the level of electricity generation from each of the eight available energy sources. Optimal control theory is used to find the optimum decision policies for integration of renewable energy sources into the national power gird of any country. As a case study for our numerical results, official released data of United States Energy Information Administration website is used for the level of electricity generation from each of the energy sources mentioned above. Different scenarios are considered for the electricity demand. These range from U.S prediction for twenty years plan period to two percent annual growth rate for different plan periods of twenty and thirty years. The proposed methodology is general enough and hence applies to other energy problems with slight modifications based on the planner's objectives.
