Grid Energy Storage Dispatch Using Contracted Power Aggregation

The patent aggregates multiple energy storage devices into a unified system managed by a central management device. This merging approach combines the stored electric energy from individual devices (each providing only several kilowatts) to achieve a collective capacity sufficient for large-scale power grid stabilization, directly resolving the contradiction between individual device limitations and system-level reliability requirements

The management device performs multiple functions including receiving contracted power supply information, coordinating dispatch operations across multiple energy storage devices, and stabilizing power supply to the grid. This multi-functional approach consolidates what would otherwise require separate systems into a single universal controller, addressing the complexity concern while achieving reliability goals

The patent explicitly addresses the insufficiency of individual user stored electric energy by merging multiple energy storage devices into a coordinated system. The aggregation transforms individually inadequate capacity (several kilowatts per user) into collectively sufficient capacity for grid-scale reliability, directly resolving the contradiction between system simplicity and power supply reliability

The management device serves as an intermediary that coordinates between individual energy storage devices and the power grid. It receives contracted power supply information and translates it into coordinated dispatch commands, enabling individual simple devices to collectively achieve complex reliability goals without requiring each device to be independently complex
