Innovation Solution
A multi-mode, cross-platform design system for microgrid controllers that includes a host machine with a microgrid simulator, monitoring system, and analysis services, allowing users to design, test, and deploy control logic offline or in real-time, using graphical or programmatic approaches, and enabling hot-swapping of control logic without decommissioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If microgrid control systems use traditional design and deployment methods, then development is straightforward, but the design, deployment, and monitoring process is slow and costly
Solution Approach 1:
The system performs preliminary simulation and validation of control logic in a virtual environment before actual deployment to the microgrid controller. The design system allows users to create, simulate, and verify control logic offline, then deploy pre-validated logic to the controller, eliminating the need for time-consuming on-site testing and debugging.
Solution Approach 2:
The system creates a virtual copy of the microgrid controller and its operating environment within the design system. This virtual controller replica allows for realistic simulation and testing of control logic without affecting the actual deployed system, enabling rapid iteration and validation.
2Adaptability or versatility
If microgrid control systems are designed with high flexibility for islanding mode, then energy independence is achieved, but system complexity increases
Solution Approach 1:
The control logic is segmented into modular, reusable components that can be independently designed, simulated, and validated. The design system provides a library of pre-built control blocks for common microgrid functions (synchronization, load management, protection), which can be assembled to create islanding capabilities without designing everything from scratch, reducing overall complexity.
Solution Approach 2:
The control logic designed in the system is platform-agnostic and can operate in multiple modes (grid-connected, islanded, transition). A single control logic design can serve multiple functions and scenarios, reducing the need for separate specialized controllers for different operating modes.
3Reliability
If control logic is deployed to microgrid controllers, then the system can operate autonomously, but any changes require decommissioning and redeployment
Solution Approach 1:
All control logic changes are validated through simulation in the design system before deployment. The virtual controller in the design environment serves as a safety net, allowing users to test updated logic thoroughly offline, ensuring reliability is maintained while enabling easy updates without risking field system stability.
4Reliability
If microgrid controllers are designed to handle abnormal conditions, then service continuity is maintained, but the design and testing process becomes more difficult
Solution Approach 1:
The design system enables preliminary testing of control logic under various abnormal conditions (faults, disturbances, transitions) in a safe virtual environment before field deployment. Users can simulate rare or dangerous scenarios that would be difficult or unsafe to reproduce in the actual microgrid, thoroughly validating abnormal condition handling.
