Photovoltaic power generation, diesel generation and energy storage integrated solution for oil and gas extraction

The ACADIE NEW ENERGY (ANE) 125kW/261kWh integrated liquid-cooled energy storage system is adopted. Additionally, a photovoltaic MPPT module and a diesel generator interface component are configured to form an integrated system for photovoltaic-diesel generator energy storage system. Through the EMS within the system, the complementary input of photovoltaic and diesel generator is achieved, ensuring the stable and reliable operation of the oil well pumping machine in the absence of grid power supply.

The oil wells located in remote oil areas are not covered by the power grid, so diesel generators are needed to provide power for the pumping machines. The diesel generator drive has problems such as high production costs, high labor intensity, and poor safety and stability. Using a photovoltaic-storage system to power the pumping machines can reduce production costs and achieve green, low-carbon and sustainable development of the oilfield.

• Cost savings

  No need for diesel supply and transportation, thus saving on fuel costs and personnel transportation costs.

  Remote monitoring enables personnel to avoid frequent on-site operations, reducing costs related to diesel engine regular startups and maintenance.

• Stability and reliability

  Diesel engines have poor reliability. In contrast, photovoltaic and energy storage systems have extremely high reliability and can be used for over ten years.

• Zero carbon extraction

  Photovoltaic power generation drives the pumping unit for oil extraction, eliminating the need for external power grid connection, achieving zero carbon extraction.

The integrated air-cooled energy storage system adopts the All-In-One design concept, integrating the power distribution system, power conversion system, battery system, EMS system, temperature control system, and fire protection system. It has a small footprint and can be multi-cabinet and multi-combined to achieve larger capacity expansion. The battery part of the system adopts a four-level fire protection and safety design, ensuring the highest system safety; the power conversion part uses the third-generation SiC components, with an energy conversion efficiency 1% to 2% higher than that of conventional systems, bringing higher economic benefits to the operators and shortening the investment recovery period. This system can be widely applied in industrial and commercial parks, charging and discharging stations, distributed photovoltaic power stations, and other scenarios.

The energy storage system has a 200% load shock resistance characteristic, capable of supporting up to 1.5 times overload for 5 consecutive seconds without voltage waveform distortion, and can operate continuously for 5 seconds under 2 times overload. It supports the connection or output of new energy sources such as diesel generators, photovoltaic power, and charging piles, and can be applied in harsh environments such as factories and construction sites, providing power support for impact loads such as mixers and air compressors. At the same time, combined with diesel generators, it can improve the operating efficiency of diesel generators and provide temporary power supply for construction sites and residents' lives.
