Research on Comprehensive Load Modeling Method of Oilfield Distribution Network with Distributed Power Sources

Under the condition of high proportion of distributed photovoltaic and energy storage devices connected to the oilfield power grid, there is a lack of load modeling method that can reflect the impact of new energy integration. This limitation hinders the safe and stable operation of the oilfield power grid. This paper proposes a comprehensive load modeling method for oilfield distribution networks with distributed power sources. The static and dynamic characteristics of generalized loads such as distributed photovoltaic, energy storage battery and pumping unit in oilfield are analyzed, and the comprehensive load model of oilfield distribution network is established. Sensitivity analysis of parameters is conducted to identify key parameters, followed by parameter identification using particle swarm optimization algorithms. Finally, the rationality and effectiveness of the comprehensive load modeling method proposed in this paper are verified by simulation and engineering examples.
