Abstract
By combining the generation control
voltage control and power flow optimization
a power flow optimization and control model for the offshore oilfield group grid is developed and its solving method is given based on an overall consideration of the power constraints
voltage quality and economic indicators. First
the power flow control problem is formulated into a multi-objective nonlinear optimization problem. Then an algorithm is proposed based on the interior-point method and branch and bound method to solve the problem. The objective weights can be adjusted to meet the requirements of different grid operation modes. Finally
the system is tested with field data of the Southwest Weizhou oilfield group grid
the results showing that by setting the weight parameter appropriately
the voltage quality and power balance can be guaranteed and the economic operation is achieved while the generation unit output is optimized.
