Steady State Analysis Of The Power System Of A Building Incorporating A 6kw Photovoltaic System InterconnectedTo The Grid

This work describesasteady state analysis of a building with a 6 kW photovoltaic system interconnected to the grid. Thebuilding is “Centro de Investigación de los Programas de Ingeniería – CIPI” at Universidad de Bogotá Jorge Tadeo Lozano, in Bogotá, Colombia. The photovoltaic system is installed on the building’s roof and it has been operating properly since the month of January 2015. Steady state analysis is performed using the ETAP™ software, with which the following types of analyzes were performed: power flow, short circuit study and harmonic analysis. The results indicate that the active power and reactive power of bus 1are within the permitted limits (48 kW, 30 kVAR); short circuit tests meet the standard ANSI C37/UL489 and the total harmonic distortion%THD does not exceed the limits permitted by the standard IEE 929-2000.
