Abstract

The invention provides a monthly maximum power load forecasting method and apparatus. The monthly maximum power load forecasting method includes the steps: acquiring the real time load data, daily maximum load data, and monthly maximum power load data of each year from a historical database; and according to the monthly maximum power load data, establishing a link relative ratio increment forecasting model or a link relative ratio growth rate forecasting model, and carrying out monthly maximum power load data forecasting. By means of the monthly maximum power load forecasting method and apparatus, the forecasting accuracy can be improved, so that the operation risk for a power plant and a power grid can be reduced. The monthly maximum power load forecasting method and apparatus have the advantages of being less in data bulk, being high in operation speed and solving the problem that the sample size is limited.

Description

technical field [0001] The present invention relates to monthly maximum power load forecasting technology, in particular to a monthly maximum power load forecasting method and device based on monthly increments. Background technique [0002] The monthly maximum power load forecast is mainly used for power system planning and power generation planning, and can also be used for system adequacy assessment, power generation contract formulation, contract power distribution, power price forecast, real-time dispatch, etc., so as to improve the economy and reliability of system operation sex. With the development of my country's electric power industry, monthly maximum power load forecasting plays an increasingly important role in power system planning and operation. The monthly maximum power load forecast is essentially the forecast of the electricity market demand. Therefore, the research on the monthly maximum power load forecast has become one of the important topics in the mo...
