Abstract

This paper presents a methodology to determine the maximum amount of renewable distributed generation that can be integrated into an electricity distribution system, without exceeding the voltage limits on buses and charging on lines and transformers. The methodology takes into account the random behavior of renewable generation and demand, as well as the three-phase model of the electricity network. To illustrate an application of the methodology, the hosting capacity of distribution systems with different lengths of lines and load levels was analyzed. The results show that in the system with long lines and lightly loaded the hosting capacity is limited by overvoltage problems, while in the system with short lines and highly loaded the hosting capacity is limited by the excessive load of the lines. Finally, it is noteworthy that the methodology presented can provide support to operators of distribution systems in the planning and operation.
