A grid-based top-down load forecasting information method for distribution network

Abstract

The invention discloses a grid-based top-down load forecasting information method for a distribution network, comprising the following steps: dividing L1 and L2 planning grids, establishing a load forecasting formula for the L2 grid, establishing a load forecasting formula for the L1 grid, Establish variable econometric equations, construct scene models, forecast variables, forecast values ​​of future electricity loads, annual maximum load forecast curves and query grid load forecast values; the present invention uses L1 and L2 planning grid division methods, and uses L1, For load forecasting in the L2 grid area, each area is forecasted separately, and the forecast results are clearer, and the assignment of various variables is brought in through the scene model, so that the load forecast takes into account various factors such as regional development data, and demonstrates the accuracy of the forecast results. The degree of reliability and accuracy makes the load forecasting information more reasonable, which has positive significance for future power grid development planning.

Description

technical field [0001] The invention relates to the technical field of electric power industry informatization, in particular to a grid-based top-down load forecasting information method for distribution networks. Background technique [0002] With the rapid development of the national economy and the continuous expansion of cities, the country has invested a lot in the construction of power points in recent years, but neglected the construction of urban distribution networks, making some urban construction ahead of power grid construction, and urban planning takes precedence over distribution network planning. Seriously restrict the development of urban distribution network; [0003] In the power system, load forecasting is the basic work in power grid planning and an important basis for formulating power development planning. Its accuracy directly affects the quality of power grid planning. Load forecasting requires strong scientificity and requires A large amount of scie...
