The Application Research of Multi-energy Complementary Power Generation Micro-grid Technology in Oilfield Peripheral Single Wells
In order to promote the combination of new energy and traditional energy and improve the efficiency of electric energy,the application of micro-grid technology of wind power,photoelectric power,diesel generating power multi-energy complementation and lithium energy storage in peripheral single well of oil field is studied.Combining with the ergodic method to evaluate the system parameters,improve the substitution rate of new energy under the principle of keeping the low cost of electricity,finally,the optimal ratio of photoelectric,wind and diesel generating capacity and energy storage capacity of the multi-energy complementary micro-grid system used in peripheral single well is given.According to the structure and working principle of the multi-energy complementary micro-grid system,the control strategy of the above electric energy types is analyzed,and the micro-grid simulation model is built in Matlab/Simulink environment,the amplitude-frequency variation of isolated island operation of micro-grid with different source-charge ratio,single energy generation operation and lithium energy storage input is analyzed.This study has a good guiding significance for the construction of multi-energy complementary power generation micro-grid in peripheral single wells,considering the stability and economy of micro-grid system.
