Abstract

The techniques described herein include for forming a power grid array with multiple power generators coupled to a power distribution unit. The power distribution unit is adapted to monitor operational data from each of the power generators to perform load balancing among the generators and to optimize the performance of the power grid array. A microgrid network is also provided within the power grid array to enable communication among the power distribution unit and the multiple generators in the array. This communication facilitates monitoring of the power grid as well as receiving and storing the operational data from each of the generators in the grid. The microgrid network can then be used to communicate the operational data over one or more connected networks allowing users to remotely access the power grid and to monitor and control the operational characteristics of the generators.
