Urban power grid has a series of problems such as limited power supply capacity and insufficient reactive power reserve. Reasonable access to VSC-HVDC can effectively alleviate the above problems. In terms of reactive power control, VSC-HVDC can be incorporated into the traditional reactive power support system of regional urban power grids by taking advantage of the rapid, flexible and controllable dynamic reactive power transfer out of VSC-HVDC. Based on BPA simulation, this paper verifies the reactive power support effect of VSC-HVDC on the power grid in the case of flexible direct interconnection of urban power grid partitions and proposes an optimization method of urban power grid partition operation based on the adjustment of VSC-HVDC operation mode, which improves the stable operation level of power grid partitions on the basis of giving full play to the flexible direct reactive power support effect.

The converter of the distributed power supply is not similar to the damping component and rotational inertia of the conventional synchronous generator, which is not conducive to the stable operation of the power system.Virtual synchronous generator control technology simulates the same or similar external characteristics as the synchronous generator, which provides strong support for the stable operation of the power system. Considering the operation characteristics of the energy storage system, it proposes the virtual synchronous generator control method considering the energy storage operation characteristics. builds A simple AC microgrid simulation system is build, and the proposed control strategy verified.
