# Africa Mining Microgrid Solutions Wind turbine + PV + diesel generator + energy storage multi-energy complementary off-grid microgrid ensures continuous production at the mine site and reduces diesel dependence. Solution Overview In response to the lack of grid power in remote mining areas in Africa, an off-grid AC-coupled microgrid is built with wind turbines, PV, diesel generators and energy storage to ensure continuous production of mining and processing operations. Key Points Wind/PV/diesel/storage multi-energy complementarity, designed specifically for off-grid mine sites PCS multi-unit parallel operation supports high-power loads of crushing and hoisting BESS smooths start-stop impacts and provides black start Significantly reduces diesel costs and carbon emissions Applicable Scenarios and Challenges Mine sites are far from the grid, with long diesel transportation distances, high costs and unstable supply, resulting in huge production loss; carbon emissions and ESG pressure are rising. VGRID System Composition **Power Conversion System (PCS)**: Multi-unit parallel operation supports large-capacity loads, enabling unified conversion and dispatch of wind/PV/diesel/storage. **Static Transfer Switch (STS)**: Fast switching between diesel generators and the microgrid, avoiding start-stop impacts of large equipment. **Battery Energy Storage System (BESS)**: Provides high-power frequency regulation and peak support, smoothing impact loads such as mining truck charging. **Energy Management System (EMS)**: Based on production scheduling and economic dispatch, prioritizes consumption of wind and PV, and starts/stops diesel generators as appropriate. **Microgrid AC Cabinet (MPS)**: Mining-grade protection and AC distribution, adapting to dust, vibration and high-temperature environments. Core Value Reduces diesel consumption by 30–50%, cutting long-distance transportation costs Improves power supply continuity, reducing production loss Meets mining ESG and carbon reduction requirements Can be expanded as production capacity grows Typical Applications Suitable for off-grid power supply and capacity expansion support for gold mines, copper mines and stone quarries. Delivery and Support VGRID POWER (VGRID) provides integrated delivery from site assessment, system design, core equipment manufacturing (PCS/STS/BESS/MPS) to commissioning and remote O&M. Welcome to contact us for customized solutions and quotations. ## Can the mining microgrid support large crushing and hoisting equipment? Yes. The PCS supports multi-unit parallel connection and high-power output, the BESS provides peak shaving and frequency regulation, and the STS isolates startup and shutdown impacts. ## How can the risk of power outages at the mine site be controlled? The EMS monitors in real time, the diesel generator serves as a backup power source, and BESS black start ensures critical loads are restored first. ## How should wind power and photovoltaic power be proportioned in the mining area? Optimize according to resources and load curves. The EMS prioritizes the consumption of wind and solar power, and diesel is started only under extreme conditions or when resources are lacking. ## The mining area has a harsh environment. How reliable is the equipment? The core cabinets have a high protection rating and adapt to dust and temperature changes. The modular design facilitates rapid on-site replacement.
