A Study on Primary Energy and Secondary Energy Price in Distributed Energy Projects

摘要

This paper constructed an energy configuration model with economic optimization in distributed energy system.On this basis,we carried out the sensitivity analysis of the price of large power grid,natural gas,cooling,heating and secondary power for the economic optimized results.And then,we have analyzed the critical value point of new energy conversion technologies appear or old disappear with the change of those energy price.In this paper,the secondary power price is same with the price of large power grid.In this study,an economic analysis of a distributed energy station project has been completed,which is a commercial complex in Shanghai.The results show that the power price have a biggest impact to-F value,and the influence of heating price is minimum,and supposing that self-generating electricity is grid-connected with no power injection.And at last,wre find that the energy conversion technologies appear in different place of different scenario.
