Abstract
The constant incentives for distributed generation (DG) have led to a significant growth in the number of photovoltaic generators connected to electricity distribution systems. However, the effect of DG on low voltage networks is complex and difficult to analyze, since several factors, such as the ambient temperature, solar radiation and rated power of the generators, influence the power available in the electrical system. In this study, the limits of photovoltaic generation insertion in electricity networks were determined through the analysis of the impacts on technical losses and the voltage levels in steady state. Real parameters of feeder systems in the Celesc Distribution network were considered and simulations were performed using MATLAB and OpenDSS software. In addition, different combinations of power and location of the generating units were randomly selected and analyzed using the Monte Carlo method. Based on the results obtained, limits for the insertion of photovoltaic generation in the feeder systems under study were defined.
