The invention provides a coordinated optimization configuration method for an alternating-current grid and a synchronous phase modifier. The coordinated optimization configuration method is used for solving the transient overvoltage problem and the extra-high-voltage direct-current commutation failure problem caused by extra-high-voltage direct-current bipolar locking faults. The method comprises the following steps: firstly, collecting power grid data, and respectively constructing a grid planning main model including investment and maintenance of alternating-current grid and synchronous phase modifier planning and an operation sub-model including thermal power generating unit operation cost, standby cost and load shedding penalty cost; secondly, constructing a load and new energy output uncertainty model based on a comprehensive norm theory; finally, based on a load and new energy output uncertainty model, integrating and simplifying the grid planning main model and the operation sub-model into a double-lay
