Evaluation of the generation and protection capabilities of a grid-connected microgrid

Abstract

Microgrids have been recognized for benefits to the electrical system such as improved reliability and reduced trans-mission costs and pollutant emissions. The study of microgrids makes it necessary to know and quantify the performance of tech-nical aspects and identify characteristics to improve their perfor-mance. The paperproposes to evaluate the performance of gener-ation and protection of a microgrid connected to the grid based on a procedure that includes the definition of indicators, the use of Power Factory software to obtain results and the weighting of in-dicators based on the DEMATEL technique. The laboratory mi-crogrid studied is located at the Universidad Industrial de Santan-derand has three 1.5 kW photovoltaic systems and meets de-mands of 5 and 10 kWh/day. The results show that its generation and protection capacities have a high performance.
