Solution Overview
Problem
Fixed-location micro-grid systems are inadequate for areas with space or time limitations, and there is a growing demand for mobile renewable energy solutions to overcome these constraints and integrate renewable energy sources effectively.
Innovation Solution
A mobile micro-grid system comprising a container with multiple power systems (DC and AC), bidirectional converters, transformers, and a control circuit that selectively uses renewable and non-renewable energy sources to provide power to external loads, prioritizing renewable energy when available and supplementing with energy storage and external grids as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-location micro-grid system is used, then power generation is stable and reliable, but it cannot be deployed in areas with space limitations or temporary power needs
Solution Approach 1:
The micro-grid system is designed as a mobile container that can be dynamically relocated to different positions. The container houses all necessary power generation equipment (solar panels, wind turbines, batteries) and can be moved via vehicle to serve temporary or remote locations, thus achieving adaptability while maintaining system reliability through integrated power management
Solution Approach 2:
The mobile micro-grid container is designed to serve multiple functions: it can generate power from multiple sources (solar, wind, battery), connect to external grids when available, and provide power to various types of loads (residential, commercial, emergency). This multi-functionality allows the same system to adapt to different deployment scenarios while maintaining reliable operation
2Reliability
If multiple power systems and energy sources are integrated, then power supply reliability and flexibility are improved, but system complexity increases
Solution Approach 1:
Multiple power systems (solar, wind, battery storage, AC/DC conversion) are merged into a single integrated mobile container. The control system unifies management of all these components, coordinating their operation to ensure reliable power supply while reducing the overall system complexity compared to having separate distributed systems
Solution Approach 2:
A central control circuit acts as an intermediary between all power generation components, energy storage devices, and load outputs. This intermediary coordinates power flow, manages charging/discharging cycles, and switches between different power sources, simplifying the complex interactions between multiple systems while maintaining reliability
3Object-generated harmful factors
If renewable energy sources are prioritized, then environmental sustainability is improved, but power supply consistency may be compromised
Solution Approach 1:
Energy storage batteries are charged in advance during periods of high renewable energy generation or low demand. This preliminary action ensures that stored energy is available to maintain consistent power supply when renewable sources are insufficient, thus supporting both environmental sustainability and power supply reliability
Solution Approach 2:
The system dynamically adjusts the mix of power sources based on real-time conditions. When renewable energy is abundant, it prioritizes solar and wind power; when generation is insufficient, it automatically transitions to battery storage or external grid power. This dynamic adjustment maintains both environmental benefits and consistent power supply

AI summary
A system and a control method of a mobile micro-grid are provided. The mobile micro-grid system includes a renewable energy source and a non-renewable energy source which are in a container. The control method includes supplying the renewable energy source as a primary power supply to an external load; and determining whether the electricity of the renewable energy source is sufficient. If the electricity of the renewable energy source is sufficient, then the renewable energy source provides electricity to the external load; if the electricity of the renewable energy source is not sufficient, then the renewable energy source and non-renewable energy source provide electricity to the external load. If an external power source, which is a renewable-energy-type power source, is connected to the mobile micro-grid system, then the renewable energy source and external power source work as the primary power supply.
