With the penetration of distributed renewable energy and the development of<br/><br/>semiconductor technology, power electronic devices could be utilized to interface re-<br/><br/>newable energy generation and the distribution power grid. However, when directly<br/><br/>connected to the power grid, the semiconductors inside the power electronic devices<br/><br/>could be vulnerable to the power system transient, especially to lightning strikes.<br/><br/>The work of this research focuses on the insulation coordination of power elec-<br/><br/>tronic devices connected directly to the power distribution system. The Solid State<br/><br/>Transformer (SST) in Future Renewable Electric Energy Delivery and Management<br/><br/>(FREEDM) system could be a good example for grid connected power electronic<br/><br/>devices. Simulations were conducted in Power Systems Computer Aided Design<br/><br/>(PSCAD) software. A simulation done to the FREEDM SST showed primary re-<br/><br/>sults which were then compare to simulation done to the grid-connected operating<br/><br/>Voltage Source Converter (VSC) to get more objective results.<br/><br/>Based on the simulation results, voltage surges caused by lightning strikes could<br/><br/>result in damage on the grid-connected electronic devices. Placing Metal Oxide Surge<br/><br/>Arresers (MOSA, also known as Metal Oxide Surge Varistor, MOV) at the front lter<br/><br/>could provide eective protection for those devices from power transient. Part of this<br/><br/>research work was published as a conference paper and was presented at CIGRE US<br/><br/>National Conference: Grid of the Future Symposium [1] and North American Power<br/><br/>Symposium [2].
