Abstract :
The Transformerless Intelligent Power Substation (TIPS) has been proposed as a replacement for the traditional distribution transformer in future power grids due to its improved voltage and power quality regulation capabilities. This system provides several benefits, but the use of power electronic devices imposes limitations on the TIPS´s overloading and temporary overvoltage withstand capabilities. The overloading limits and the behavior of the TIPS under the temporary overvoltage impulse are examined in this paper, laying the groundwork to develop methods to mitigate these limitations.
