Energy storage solution for oilfield pumping units

How can energy storage systems be used for energy management?

Possible solutions are the intensified deployment of energy storage systems (ESS) to supply different ancillary services for frequency control (FCR, aFRR, mFRR), a specific inertia management of synchronous generators (e.g. used especially in the hydropower sector) or the further development of grid forming inverter , .

Can secondary balance energy-saving system reduce pumping unit energy consumption?

Using AMEsim simulation platform, compare the load fluctuation and motor energy consumption before and after setting up secondary balance energy-saving system, which proves that the system can effectively reduce the pumping unit energy consumption problem caused by the fluctuating load rate. A self-learning method based on MPGA is developed.

How can a hybrid pumping unit save energy?

As can be seen from Figs. 8 and 9, energy-saving system of secondary balance for the hybrid power of the pumping unit can well eliminate the negative torque of the motor of the traditional pumping unit and add energy to the upper stroke, effectively reducing the electrical energy consumption caused by the larger load fluctuation.

What is pumping unit?

The pumping unit is the main equipment for oil production in the oilfield. However, its serious energy consumption has greatly increased the cost of oil extraction. The reason of this phenomenon is...

What is the secondary balance system of pumping units?

The research and development of the secondary balance system of pumping units is imminent. The key to the design of the secondary balance system is to reduce the wave peak and trough of the load, which involves the storage and release of energy.

How can PHES be a viable energy storage system?

The revenue of operation must be maximized by simultaneously achieving high socio-economic and ecological acceptance to make the construction of new PHES viable. On a global scale, PHES accounts for most of the installed ESS , . In Europe and Germany, the installed energy storage capacity consists mainly of PHES .
