Abstract
Conference Title: 2015 IEEE Power & Energy Society General Meeting Conference Start Date: 2015, July 26 Conference End Date: 2015, July 30 Conference Location: Denver, CO, USA Starting of large induction motors may produce voltage dip in a weak microgrid because of high current and reactive power demand in transient period. This paper develops a solution for black start issue of an Induction Motor (IM) using Voltage-Sourced Converter (VSC) interfaced source in an autonomous microgrid. This paper provides procedures and techniques for controlling the VSC. First, a dynamic model of a microgrid is analyzed to provide a designing criteria of VSC's controller. Vector control is implemented to control the voltage and frequency of the VSC at autonomous mode. Second, the issue of black start of IM is investigated and analyzed. A proposed technique is presented in order to solve the overcurrent and voltage dip due to black start of IM. Finally, a microgrid is modeled and simulated in PSCAD/EMTDC to validate the proposed technique on black start.
