Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity. In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated. When the hosting capacity had been decided attempts have been made to increase the hosting capacity with four different measures. The measures examined are line gain, tap changer, reactive compensation and voltage regulation in the form of MPV. For the investigated network the hosting capacity varied virtuously. For all three grids were too high voltage during low load with maximum power production however the reason that the performance of the grid became unacceptable. The reasons that the voltage became unacceptable at different amounts of microproduction depends mainly on four things. These were the voltage in the substation, the amount of customers in the grid, the quality of the lines and the line length between the customer and substation. The best measure to increase the hosting capacity in a net is line gain in the most of the cases. Tap changer and the voltage regulator MPV are however two other measures that are recommended, but mainly as temporary solutions. Reactive compensation on the other hand is something that isn’t recommended based on this report.
