DETERMINATION OF THE FEASIBILITY OF IMPLEMENTING A ROOFTOP-TYPE GRID PHOTOELECTRIC STATION FOR THE FIRST BUILDING OF THE KHERSON NATIONAL TECHNICAL UNIVERSITY

Abstract

The article presents the results of modeling the operation of a rooftop grid photovoltaic station for the first building of the Kherson National Technical University and determines the feasibility of implementing such a system in practice.When modeling, it was taken into account that the configuration of the roof of the educational building is quite complex and multi-level, as well as the fact that the problem lies in the operating mode (morning-day mode) and seasonality of the higher education institution’s operation (maximum electricity consumption does not coincide with the season of maximum solar insolation).In the Gelioscope software complex, a rooftop grid photovoltaic station with a stationary and single-axis tracking system of photovoltaic modules has been developed. In particular, a solid «false-sloping» structure with the orientation of photovoltaic modules to the southwest, the angle of inclination of the module and a single-axis tracking system with block-positioned photovoltaic modules oriented to the south are provided. Five options were proposed, which were divided into two groups.The operation of all proposed project options was simulated, for each of which the parameters of the components of the grid photovoltaic station system were determined taking into account the configuration of the roof of the facility; equipment was selected to complete the system, taking into account the optimal location of photovoltaic batteries with minimal shading of the elements.An electrical diagram of the elements was developed, data on the performance of each of the proposed options was obtained, taking into account losses in the system. Based on the results, a feasibility study was performed on the feasibility of implementing a grid photovoltaic station for this facility. Based on the analysis of the performance of the projects, a variant of using the system at a «green» tariff was proposed.
