Embodiment Construction
[0045] A method for configuring virtual inertia based on Voronoi diagram center of gravity interpolation method, comprising the following steps:
[0046] Step 1. Establish the second-order dynamic model optimization model of the new energy system;
[0047] Step 2, establishing a system virtual inertia planning model;
[0048] Step 3. Solve the optimal value of the virtual inertia configuration of the system through the center of gravity interpolation method of the Voronoi diagram;
[0049] Step 4. Use the phase angle difference oscillation between nodes to verify the pros and cons of the results.
[0050] In step 1, only the mechanical characteristics of the power system are considered to establish the second-order dynamic model optimization model of the new energy system, and its mechanical characteristic equation is:
[0051]
[0052] In the formula: M, D are inertia coefficient and damping number respectively; P m is the mechanical input system power, P e is the elec...
