Abstract

The invention relates to a power load forecasting method based on historical annual weather rules, and belongs to the technical field of electric power systems. The method includes: S1. Determine the area range of the electricity load, and divide the sub-load units or sub-power supply areas according to the actual situation, and formulate the network topology structure diagram of the geographical location relationship; S2: according to the network topology structure; S3. Input the history of the current month 12-month monthly cumulative data of electricity load; S4. Determine the weighted sub-factor of the load nature; S5: Obtain the per-unit value of the current historical 12-month load forecast by month; S6: Use the multivariate nonlinear fitting method to optimize The current historical 12-month load change curve and fitting relationship; S7: Get the power load of the next three months, six months or 12 months including the current month; S8: Check and correct the power load change curve , modify the load forecast results for the next month. Gradually achieve the goal of being as close as possible to the actual power load in the future.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and relates to a power consumption load prediction method based on historical annual weather laws. Background technique [0002] Electricity load forecasting is the basic guarantee for grid planning, meeting the needs of users, and improving the awareness of reliable service in the grid. For a long time, the power grid has carried out a lot of load forecasting research, and put forward many methods of electricity load forecasting, but so far there is still no reliable and accurate method. [0003] Therefore, it is urgent to propose an accurate and simple power load forecasting method to promote the development of power grid planning and power consumption planning. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of the present invention is to provide an electricity load prediction method based on historical annual weather patterns. [0005] To achieve the above ob...
