Embodiment Construction
[0037] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0038] A medium- and long-term power load combination forecasting method for large cities based on support vector machines, such as figure 1 shown, including the following steps:
[0039] Step 1. Taking the zonal eigenvalues and zonal areas of medium and long-term loads in large cities as input, a medium and long-term load forecasting method for large cities based on the load density method is proposed;
[0040] The step 1 of the medium and long-term load forecasting method for large cities based on the load density method includes the following steps:
[0041] (1) According to the administrative division of the city, carry out regional or functional division of large cities, analyze the load characteristics of the urban power grid, and calculate the current regional load density W according to the calculation principles of the "Guidelines for U...
