Algoritem za celostno vrednotenje fotovoltaičnega in vetrnega potenciala večjih geografskih območij : doktorska disertacija by Niko Lukač( Book )

1 edition published in 2016 in Slovenian and held by 3 WorldCat member libraries worldwide

V doktorski disertaciji predlagamo nov algoritem za izračun fotovoltaičnega in vetrnega potenciala nad večjim geografskim območjem. Pri tem veliko geografsko območje predstavimo v topološki strukturi mreže, ki jo skonstruiramo iz visokoločljivostnih podatkov laserskega snemanja LiDAR. Najprej relativno, glede na lokacijo, izračunamo položaj Sonca, senčenje ter anizotropno obsevanje na površino, z upoštevanjem večletnih meritev direktnega in difuznega obsevanja. Izračunano trenutno vrednost globalnega obsevanja integriramo po času, pri čemer upoštevamo tudi od globalnega obsevanja nelinearno odvisno karakteristiko izkoristka (učinkovitosti) obravnavanega fotovoltaičnega sistema. V drugem delu doktorske disertacije predstavimo novo metodologijo za izračun vetrnega potenciala nad dano mrežo, kjer z računalniško simulacijo določimo vetrni tok kot skupek zračnih molekul z Lagrangeovo metodo hidrodinamike zglajenih delcev ter modelom turbulence temelječim na Reynoldsovim povprečenjem. Za izvedbo izračuna potencialnega gibanja vetra upoštevamo še večletne podatke meteoroloških meritev hitrosti in smeri vetra, s katerimi zgradimo logaritmični vetrni profil za določitev začetnih pogojev delcev vetra. Za izračun izhodne moči uporabimo nelinearno karakteristiko moči vetrne elektrarne, ki je odvisna od hitrosti vetra. Integracijo slednje po času uporabimo za napoved proizvodnje električne energije. Obe metodologiji združimo v predlagan algoritem, ki ga implementiramo na grafični procesni enoti s tehnologijo CUDA, s čimer dosežemo učinkovito paralelno izvajanje v doglednem času. V eksperimentalnem delu doktorske disertacije s primerjavo izračunanih vrednosti in neodvisnih meritev ovrednotimo natančnost in točnost izračuna glede na vhodne podatke. Z algoritmom tudi vrednotimo fotovoltaični in vetrni potencial večjega geografskega območja mesta Maribor. Pri fotovoltaičnem potencialu v povprečju dosežemo točnost glede na podatke meritev do 97%, pri vetrnem potencialu pa do 92%

DETECTION OF PLANAR POINTS FOR BUILDING EXTRACTION FROM LIDAR DATA BASED ON DIFFERENTIAL MORPHOLOGICAL AND ATTRIBUTE PROFILES by D Mongus( )

1 edition published in 2013 in English and held by 2 WorldCat member libraries worldwide

This paper considers a new method for building-extraction from LiDAR data. This method uses multi-scale levelling schema or MSLS-segmentation based on differential morphological profiles for removing non-building points from LiDAR data during the data denoising step. A new morphological algorithm is proposed for the detection of flat regions and obtaining a set of building-candidates. This binarisation step is made by using differential attribute profiles based on the sum of the second-order morphological gradients. Any distinction between flat and rough surfaces is achieved by area-opening, as applied within each attribute-zone. Thus, the detection of the flat regions is essentially based on the average gradient contained withina region, whilst avoiding subtractive filtering rule. Finally, the shapes of the flat-regions are considered during the building-recognition step. A binary shape-compactness attribute opening is used for this purpose. The efficiency of the proposed method was demonstrated on three test LiDAR datasets containing buildings of different sizes, shapes, and structures. As shown by the experiments, the average quality of the buildings-extraction was more than 95%, with 96%correctness, and 98%completeness. In terms of quality, this method is comparable with TerraScan R , but both methods significantly differ when comparing correctness and completeness of the results
