Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single demand set-point is used to control energy storage systems, then the control method is simple, but the system requires impractical quantities of energy storage capacity and may run out of energy due to over-reaction
Solution Approach 1:
The patent divides the energy storage system into multiple independent storage devices (first storage device, second storage device, etc.) that can be separately controlled. Each device has its own system controller that independently manages charging and discharging operations, allowing the system to distribute energy management tasks across multiple units rather than relying on a single oversized storage device.
Solution Approach 2:
The patent implements dynamic reconfiguration capabilities where the network topology of storage devices can be automatically adjusted based on real-time conditions. The power monitor controller receives configuration information from storage devices and dynamically reconfigures the network connections, enabling the system to adapt its structure to optimize performance and prevent energy depletion scenarios.
2Reliability
If multiple discrete energy storage systems are used to control demand at larger load locations, then the power control capability is improved, but the system becomes difficult to reconfigure and maintain
Solution Approach 1:
The patent creates a universal power monitor controller that can manage multiple different storage devices through a standardized interface. The controller receives configuration information from various storage devices and can reconfigure the entire network dynamically, making the system adaptable to different device types and configurations without requiring custom setup for each location.
Solution Approach 2:
The patent implements automatic site layout discovery where storage devices automatically provide their configuration information to the power monitor controller. The system performs self-configuration and auto-discovery of the network topology, eliminating the need for manual setup and making the system easily reconfigurable when devices are added, removed, or replaced.
3Ease of manufacture
If conventional energy storage systems are preconfigured for specific phase and voltage requirements, then the initial setup is straightforward, but the system cannot be easily reconfigured for system changes or location changes
Solution Approach 1:
The patent implements dynamic reconfiguration where the power monitor controller can adjust the network topology and operational parameters in real-time based on changing conditions. The system receives configuration information from storage devices and automatically reconfigures connections and control parameters, enabling adaptation to different phases, voltages, and locations without manual reconfiguration.
Solution Approach 2:
The patent enables dynamic changes in operational parameters such as phase configuration and voltage levels through automated control. The power monitor controller adjusts these parameters based on received configuration information from storage devices, allowing the system to adapt to different electrical environments and requirements without physical reconfiguration or manual intervention.

AI summary
Embodiments of the present invention include control methods employed in multiphase distributed energy storage systems that are located behind utility meters typically located at, but not limited to, medium and large commercial and industrial locations. Current solutions for these types of electric load locations entail multiple discrete energy storage systems, where if any piece of an energy storage system is damaged, the ability of the complete power control strategy at the entire electric load location is at risk of becoming inoperable. Some embodiments of the invention include hardware and methods for dynamically reconfiguring networks of distributed energy storage systems that are able to provide automatic site layout discovery using a formed auto-discovering network formed at an electric load location.
