Dynamic Lightning Protection of Microgrids with High Proportion of Photovoltaic Power Generation

As one of the most prevalent kinds of Renewable energy resources (RES), distributed photovoltaic (PV) generations are widely used in Microgrids. During the lightning storms, the Microgrids with more PV would face more challenges of reliability in practice. To improve the lightning performance of Microgrids, the paper presented a mode named Dynamic Lightning Protection (DLP). The paper also proposed a dynamic multilevel control model which shows advantages on the adjustment of power exchange and dynamic balance so as to enhance the reliability of system. The dynamic protection mode, which was discussed in this paper, could provide a more effective lightning protection solution for the Microgrids with high proportion of photovoltaic power generation.
