Abstract

Alternative and embedded generation both make the decentralized approach to electricity generation, and they offset the grid import power near the consumption point. These are two different philosophies, but they have similar overall impacts on the environment, society, and the electricity economy. This paper aims to test both philosophies to evaluate the influence of alternative sources in a radial distribution grid on rapid-voltage changes and to examine the quality of the power factor of an embedded generation if reactive power is not compensated. The study is narrowed to photovoltaic generation as the popular renewable source due to its less complexity in design and operation. The effects are evaluated using MATLAB and Power software for the alternative and embedded sources, respectively. Simulation results show the impact in both scenarios, where the alternative has a significant rapid voltage change and a deteriorating power factor for the embedded sources if reactive power is not compensated.
