A mobile microgrid is a self-contained power system that can be transported and deployed quickly to provide electricity in remote or disaster-affected areas. These systems typically include generation, storage, and distribution components mounted in a trailer or container. The ability to relocate the microgrid as demand shifts makes it suitable for military operations, emergency response, mining exploration, and construction projects. INJET HanCang focuses on the integration of storage within these mobile systems to enhance fuel efficiency and power quality.
The core components of a mobile microgrid include a power source, energy storage, a distribution panel, and a control system. The power source may be a diesel generator, a solar array deployed alongside the trailer, or both. The energy storage system in a mobile microgrid serves multiple functions: it absorbs excess generation, provides power during generator transients, and maintains supply during short generator outages. The control system manages the interaction between these components to maintain voltage and frequency stability. INJET HanCang's mobile microgrid designs use a modular battery system that can be configured for different capacities based on the expected load and duration of deployment.
For a microgrid to be mobile, its weight and dimensions must comply with road transport regulations. The total weight, including the trailer, generator, batteries, and cabling, must not exceed axle load limits. The battery system is one of the heavier components. The use of lithium-ion batteries with a high energy density reduces weight compared to lead-acid batteries, allowing for more energy storage within the weight limit. INJET HanCang uses lightweight aluminum enclosures for the battery modules to reduce overall system weight. The trailer is designed with a low center of gravity to maintain stability during transport and deployment.
The time required to set up a mobile microgrid is a key performance metric. Deployment includes unloading the trailer, connecting the load cables, and starting the system. Pre-wired connections and plug-and-play interfaces reduce setup time. The distribution panel includes outlets for common load types. INJET HanCang systems feature color-coded cabling and quick-connect terminals that allow for installation without specialized tools. The system's control software includes a startup sequence that automatically checks for ground faults and correct phase rotation before applying power to the load, reducing the risk of damage to connected equipment.
For deployments lasting more than a few days, adding solar panels to the mobile microgrid reduces generator fuel consumption. The solar array can be ground-mounted beside the trailer or integrated into the trailer's roof. The solar output is used to charge the battery during the day. The generator is then used to charge the battery during the night or during periods of low solar irradiation. The control system prioritizes solar power to minimize generator runtime. INJET HanCang's mobile microgrid controller includes a solar charge controller that operates independently of the generator, allowing for simultaneous charging from both sources if needed.
Loads in mobile deployments often include motors, compressors, and electronic equipment that are sensitive to voltage fluctuations. The generator's output may vary with load changes, causing flicker or frequency deviations. The battery system in a mobile microgrid provides active power filtering, correcting voltage sags and swells. The inverter can produce reactive power to support the generator's voltage regulation. This improves the power quality for sensitive loads and reduces the risk of equipment damage. INJET HanCang's inverter is configured for grid-forming mode in islanded operation, establishing a stable voltage reference for the entire microgrid.
Field data from mobile microgrid operations indicates a reduction in fuel consumption when storage is used to handle transient loads. Without storage, the generator must respond to every load change, operating at partial loads during low demand periods. With storage, the generator can operate at a fixed output, charging the battery. The battery supplies the load when it exceeds the generator's set point. This strategy increases the generator's average loading, improving its fuel efficiency. INJET HanCang's system logs fuel consumption and battery throughput, providing operators with data to optimize future deployments.
Mobile microgrids are often deployed in harsh environments, including deserts, jungles, and arctic regions. The equipment must withstand extreme temperatures, humidity, and dust. The enclosures are constructed from corrosion-resistant materials. The cooling system is designed to operate in high ambient temperatures without derating the battery. The control panel is sealed against moisture ingress. INJET HanCang tests its mobile systems to environmental standards, ensuring operation across a defined temperature range.
For multiple mobile microgrids deployed at different sites, a centralized monitoring system is needed. The microgrid's control system transmits data on generator status, battery state of charge, and load consumption to a remote operations center. The communication link may be satellite or cellular, depending on the site. The remote monitoring system alerts operators to faults, low fuel, or battery degradation. INJET HanCang provides a web-based monitoring platform that aggregates data from all deployed units, allowing for centralized management of fleet operations.
Mobile microgrids provide a flexible power solution for temporary or remote applications. The inclusion of energy storage within these systems improves fuel efficiency, power quality, and operational reliability. INJET HanCang designs its mobile microgrids with a focus on transportability, rapid deployment, and integration with renewable energy sources.
