在电力工业放松管制的环境下,输电扩展规划问题将会变得更为复杂。作者引入了帕累托最优、帕累托改进和社会福利等经济学概念,试图从根本上探索市场环境下输电扩展规划所应遵循的经济准则。基于帕累托改进的准则,提出了一种输电扩展模型。该模型涉及电力市场机制和输电成本分摊方案等因素。在节点边际定价的市场机制下,提出了三个简单的输电成本分摊方案。为了展示所建模型及所提出的输电成本分摊方案的内涵和特点,对一个六节点系统算例进行了详尽的分析。

The Y,f.and Ag tridoped TiO_(2)/SnO_(2) composite nanocrystalline f.lm(Yf.g–TS)with prominent photocatalytic perf.rmance was prepared by the modif.ed sol–gel method and was characterized by utilizing X-ray dif.raction(XRD),dif.erential thermal and thermogravimetric(DTA–TG)analysis,scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),Brunauer–Emmett–Teller(BET)method,ultraviolet–visible dif.use ref.ectance spectroscopy(UV–vis DRS),and photoluminescence(PL).The XRD and DTA–TG results expose that the Yf.g–TS catalyst is a mixed phase consisting of.anatase,rutile,and chlorargyrite,which is benef.cial to improving the photocatalytic perf.rmance of.TiO_(2).The SEM,TEM,and BET results disclose that the Yf.g–TS f.lm has smaller nanoparticles,higher specif.c surf.ce area,and narrower pore size compared with pure TiO_(2) *** XRD and TEM results exhibit that a part of.yttrium can enter the TiO_(2) lattice to induce lattice *** XPS results conf.rm the presence of.Y^(3+)state in the Yf.g–TS sample,and Y^(3+)ions can act as the trapping site of.electrons to expedite the separation of.electrons and *** UV–vis DRS results reveal that the Yf.g–TS f.lm has an obvious absorption edge shif. and a narrower bandgap(2.70 eV)compared with pure TiO_(2) *** PL results show that the Yf.g–TS f.lm has the highest photogenerated electrons and holes separation ef.iciency and charges transf.r ef.iciency among all *** photocatalytic activity of.the Yf.g–TS was assessed by monitoring the degradation of.methyl green and f.rmaldehyde *** results manif.st that the Yf.g–TS f.lm has high stability and excellent photocatalytic *** possible synergistic photocatalytic mechanism of.Yf.g–TS f.lms has been discussed in this paper.
