Oilfield Production Microgrid Solution
Summary: A solar-diesel-storage microgrid for gobi oilfields, reducing diesel consumption and carbon emissions at remote well sites while improving power supply resilience.
Solution Overview
For remote oilfield well sites in gobi and desert regions, a microgrid is built with PV, energy storage and diesel generation to reduce energy consumption per ton of oil produced and carbon emissions.
Key Points
- Solar-diesel-storage for gobi oilfields, reducing diesel fuel consumption and carbon emissions
- Explosion-proof AC cabinet design, meeting oil and gas zone requirements
- BESS absorbs pumping unit regenerative energy and smooths impact loads
- Improves power supply resilience for remote oil production
Applicable Scenarios and Challenges
Well sites are scattered and grid power is unavailable, making diesel transport and on-site staffing costly; continuous oil production demands extremely high power supply continuity.
VGRID System Composition
- Power Conversion System (PCS): Compatible with cyclic impact loads such as pumping units (nodding donkeys), ensuring stable power conversion.
- Static Transfer Switch (STS): Switches between diesel generation and the microgrid to prevent power loss during pumping unit start/stop.
- Battery Energy Storage System (BESS): Absorbs pumping unit regenerative energy and smooths cyclic loads, reducing diesel generation output.
- Energy Management System (EMS): Dispatches according to well site conditions, maximizing PV self-consumption and reducing idle losses.
- Microgrid AC Cabinet (MPS): Explosion-proof AC cabinet, meeting safety requirements for oil and gas zones.
Core Value
- Lower diesel consumption and transport costs
- Improved pumping continuity, reducing losses from well shutdowns
- Lower well site carbon emissions, supporting energy companies' dual carbon goals
- Unmanned/minimally staffed operation with remote O&M
Typical Applications
Suitable for off-grid or weak-grid power supply at desert oilfields, marginal well sites and gathering and transportation stations.

FAQ
How is equipment safety ensured in oilfield areas?
The AC cabinet uses an explosion-proof design, and the system provides arc and leakage current protection, meeting explosion-proof standards for oil and gas areas.
Will the cyclic load of the pumping unit damage the battery?
The PCS and BESS work together to absorb regenerative energy and smooth out surges, while the EMS optimizes charging and discharging to extend battery life.
How much diesel can an oilfield microgrid save?
With optimization based on irradiance and load, typical diesel savings are 30–60%, improving with better solar resources.
Are the devices durable in dusty and high-temperature environments?
Core equipment has a high IP rating and resists dust and thermal drift, while remote EMS reduces on-site inspections.
