Short-term hydrothermal scheduling(STHTS) is a non-linear and complex optimization problem with a set of operational hydraulic and thermal constraints. Earlier, this problem has been addressed by several classical techniques; however, due to limitations such as non-linearity and non-convexity in cost curves, artificial intelligence tools based techniques are being used to solve the STHTS problem. In this paper an improved chaotic hybrid differential evolution(ICHDE) algorithm is proposed to find an optimal solution to this problem taking into account practical constraints. A self-adjusted parameter setting is obtained in differential evolution(DE) with the application of chaos theory, and a chaotic hybridized local search mechanism is embedded in DE to effectively prevent it from premature convergence. Furthermore, heuristic constraint handling techniques without any penalty factor setting are adopted to handle the complex hydraulic and thermal constraints. The superiority and effectiveness of the developed methodology are evaluated by its application in two illustrated hydrothermal test systems taken from the literature. The transmission line losses, prohibited discharge zones of hydel plants, and ramp rate limits of thermal plants are also taken into account. The simulation results reveal that the proposed technique is competent to produce an encouraging solution as compared with other recently established evolutionary approaches.

Introduction:The ecological processes underlying the suppressive impacts of invasive species on native species diversity,both above-and below-ground,in non-native regions are not well *** therefore aimed to investigate the cross-city biogeographic patterns of arbuscular mycorrhizal(AM)diversity in Conyza canadensis rhizosphere in native(North American)and non-native(Kashmir Himalayan)***:We recovered AMF spores from rhizospheric soils of Conyza in native and non-native ranges,besides doing so from the uninvaded sites in the introduced *** extracted from AMF spores was processed for cloning and PCR-RFLP of SSU rRNA gene to yield the restriction groups(RGs)followed by their sequence analysis to determine the sequence groups(SGs).Results:The results indicated greater diversity of RGs and SGs in Conyza rhizosphere in native than in non-native *** the introduced region,however,the AMF diversity was more in uninvaded than in invaded *** species composition of AMF varied significantly between native and non-native regions and so also between invaded and uninvaded ***:Though difference in AMF diversity between Conyza invaded and uninvaded sites may be attributed to invasion,the role of other evolutionary factors seems likely for differences between the native and non-native *** suggest that the ecological processes underlying these evolutionary differences in two biogeographic regions,besides the intensity of urbanization,might play some role in these differences.
