Abstract or Summary
  • This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term power. The hardware results show the effective way that the system delivers energy to stabilize microgrid frequency. A control system is created to monitor the grid frequency and activate an inverter to either charge or discharge a bank of supercapacitors depending on the measured conditions. For example, when the frequency is measured below 60 Hz, the system injects power into the microgrid to arrest the frequency deviation; above 60 Hz the energy storage system absorbs power. For a microgrid with a high penetration of distributed renewable generation such as small scale solar and wind systems, additional stabilizing inertia, which is typically provided by large-scale synchronous generators, may be beneficial. This system adds real inertia and short-term energy storage to stabilize frequency. This thesis outlines the simulation, design and hardware testing results of this microgrid frequency stabilization system.
