A Sensor Collaborative Coverage Algorithm for Microgrid Monitoring

The distributed energy is organized in form of microgrid, which is one of the hot topics in study of current smart grid. Collaborative coverage of sensors can conduct comprehensive monitoring for micro-grid equipment and network status. It can provide a number of effective data support for power flow calcu-lation and fault analysis, which is closely related to the stability of power grid. But the transmission for a large amount of data will speed up the energy consumption of the sensor nodes and shorten the life cycle of sensor network. A sensor collaborative coverage algorithm for microgrid monitoring was proposed. In different time period, this algorithm executes the construction and schedules the connecting collaborative cover to realize the efficient utilization of energy in the sensor node and prolong the life cycle of sensor network. Simulation shows that the collaborative coverage algorithm could prolong the lifecycle of the sen-sor network significantly with high efficiency.
