[0082] A kind of wind power prediction index evaluation of grid peak-shaving capability limit, the detection method includes the following steps:
[0083] S1, read the parameters required for the calculation of predicted wind power, the calculation parameters include the installed capacity of the wind farm, and several weight values when calculating the weighted accuracy. The setting of the weight value is divided into three dimensions. The first dimension is divided by the peak, flat, and valley periods of power grid operation. The second dimension is divided by the actual value exceeding the upper limit, not exceeding the limit, and exceeding the lower limit. The value exceeds the upper limit, does not exceed the limit, and exceeds the lower limit, a total of 2*2*2=17 cases, each case corresponds to a different weight value, which can be set in advance by experienced dispatchers;
[0084] S2, read the actual data, forecast data and peak shaving capacity upper and lower lim...
