[摘要]：This is the second of a series of two articles, dealing with a new approach of environomic (thermodynamic, economic and environmental) performance Typification and optimization of power generation technologies. This part treats specifically of combined heat and power (CHP) cogeneration technologies in the context of CO2 abatement and provides a methodology for a flexible and fast project based CHP system design evaluation. One of the aspect of the approach is the post-optimization integration of the operating and capital costs, in order to effectively deal with the uncertainty of the project specific design and operation conditions (fuel, electricity and heat selling prices, project financial conditions such as investment amortization periods, annual operating hours, etc). In addition the approach also allows to efficiently evaluate the influence of the external cost such as the CO2 tax level under a tax scheme or the CO2 permit price in the emission trading market. Application examples, including gas turbine and combined cycles are treated with the proposed methodology, by using superstructure based generic environomic models and a multi-objective optimizer.
