Microgrid Energy Storage Power Allocation for State-of-Charge Balance

The patent applies local quality by allocating charge or discharge power differently to each energy storage system based on its individual characteristics (power capacity, energy capacity, state of charge). Instead of uniform distribution, each system receives a customized allocation that considers its specific capabilities and current state, thereby protecting system health while maintaining operational simplicity through centralized control logic.

The patent implements dynamics by making the charge/discharge power allocation adaptive and dynamic rather than static. The allocation continuously adjusts based on real-time state of charge levels, power capacities, and energy capacities of each system. This dynamic approach allows the system to maximize productivity when conditions permit while automatically maintaining state of charge balance, resolving the contradiction between output maximization and reliability.

The patent employs an intermediary approach by introducing a central controller that acts as a mediator between energy storage systems. This central controller receives information about system capacities and states, performs the complex allocation calculations, and distributes optimized charge/discharge commands to individual systems. This intermediary structure maintains reliability through balanced state of charge management while reducing overall system complexity by centralizing the computational burden rather than requiring complex peer-to-peer communication and consensus algorithms at each node.
