The invention discloses a load prediction analysis method for a typical urban cable pipe network system, and the method comprises the steps: constructing an urban power grid space load prediction platform based on an electric power GIS, taking the integration of basic data needed by the urban power grid space load prediction as the basis, and through load regularity analysis, spatial resolution analysis and multi-scene analysis, providing the urban power grid spatial load prediction method and prediction model, the existing urban power grid spatial load prediction method and prediction model are improved or optimized, urban power grid spatial load prediction based on multi-scale spatial resolution analysis is carried out, and optimal output of prediction load precision is realized. The software platform has the characteristics of multiple functions, easiness in operation, expandability and portability, provides powerful technical support for improving the space power load prediction precision, improving the management level of space power load prediction analysis work and ensuring the scientificity of power grid construction. The method can play an important role in a power grid planning department.
Description
Technical field [0001] The present invention relates to a typical urban cable pipe network system load prediction analysis method, which belongs to the technical field of urban network planning. Background technique [0002] Nowadays, my country's electricity market is increasingly, and power reform is constantly deepening, and power companies are their own operations and self-risk, so they must ensure the quality of the grid planning work, and ensure that the power grid is safe and efficient. Be sure to do a good job of electricity load forecasting. [0003] Today's power load prediction methods are a variety of ways to choose the most suitable grid prediction method from the many methods, so that the prediction accuracy is greatly improved. In addition, there is an in-depth understanding of various aspects of the change in power grid load. The traditional load prediction method is mainly based on the historical data, it is difficult to represent the actual spatial distribution ...
