Under the carbon peaking and carbon neutrality goals,CNPC is implementing a large layout of"wind,solar,hydro and storage integration"base in Three North Regions,promoting the integrated development of natural gas and renewables.The transformation of oilfield power grids faced a series of bottlenecks and challenges.As electricity generated by renewables gradually accesses to the internal power grid of oilfields,the difficulty of power system balance increases.Issues such as grid voltage stability and frequency stability are affected,and existing oilfield power grids struggle to ensure the safe,reliable,and economically efficient operation of the system.The article explored the grid scheduling automation system,the power intelligent control platform,and the adaptive simulation analysis of new energy integration for the Q oilfield.Through the improvement of the power scheduling automation system,functions such as power system state estimation and market transaction are achieved.The substitution of clean energy in the BW region was analyze by the application of intelligent electric power control platform.The results showed that 2.96 million yuan in electricity costs annually and 500 tons CO2 emissions reduction can be saved.The results of the adaptive simulation analysis of new energy integration indicated that when the proportion of new energy is less than 75%,the system power grid can be stabilized after oscillation.The connection point of gas turbines to the grid should be close to the central bus to prevent low system voltage and oscillation caused by long transmission lines.
