Dynamic Lightning Protection of Smart Grid distribution system

• The Smart Grid distribution systems are more decentralized and interactive.
• Dynamic Lightning Protection focuses on preventive actions for the whole system.
• Based on lightning tracking, a DLPS calculates and carries out dynamic actions.
• Dynamic hierarchical control can adjust power exchange and maintain dynamic balance.
• DLP mode is able to minimize lightning disturbances and improve system reliability.

With the integration of renewable resources, distributed generation (DG) and Microgrids, the Smart Grid distribution systems are more decentralized and interactive. As a System-level protection mode, the Dynamic Lightning Protection (DLP) focuses on the preventive actions for improving lightning performance of the whole system. In this paper, the DLP for Smart Grid distribution system is discussed. Taking advantage of the flexibility and interactivity of Smart Grid, the mode aims to maintain the system dynamic balance and minimize the lightning disturbance during the lightning storms. A dynamic hierarchical multilevel control model is also proposed in the paper, which could coordinate with a Dynamic Lightning Protection System (DLPS) to switch the control strategies, control the power exchange and improve the system reliability.
