Embodiment Construction
[0095] Such as figure 1 , 2 , 3, 4, 5-1, 5-2, a method for correcting the dynamic process simulation trajectory of power grid frequency, comprising the following steps:
[0096] Step 1) Obtain the frequency measured traces of multiple grid power shedding events by a fault recorder (commercially available product);
[0097] Step 2) Establish a simulation model and input parameters in the power system simulation software (i.e. Power System Analysis Software Package (PSASP) for short), and obtain the power grid dynamic process frequency simulation track;
[0098] Step 3) according to step 1) and step 2) establish the mathematical evaluation system of frequency emulation trajectory and measured trajectory similarity; Described mathematical evaluation system is summarized as follows:
[0099] ① Define the characteristic index of the closeness between the simulated trajectory and the measured trajectory of the frequency dynamic process, including the initial frequency drop differe...
