Problems solved by technology

[0004] However, at present, the complementarity of new energy resources and power structures among provinces in my country cannot be fully utilized. The current cross-regional power transmission capacity of the Northeast and Northwest power grids is only 19% of the installed capacity of new energy. Accommodation is the main problem factor affecting the capacity of inter-regional transmission, and the verification of renewable energy grid-connected consumption information determines the accuracy and accuracy of renewable energy grid-connected consumption

Abstract

The invention discloses a renewable energy grid-connected consumption information multi-dimensional check method and equipment. The method comprises the follow steps: S1, a relationship model betweenelectric quantity and various meteorological factors is constructed by using a support vector machine algorithm to predict the power supply situation; and S2: an abnormal power consumption identification analysis model is constructed to identify the situation of abnormal power consumption based on the K nearest neighbor classification algorithm. Compared with the methods and the equipment in the prior art, the invention discloses the renewable energy grid-connected consumption information multi-dimensional check method and equipment, the support vector machine can be used for performing effective training and can be used for obtaining very good prediction accuracy. The training time of the classifier can be shortened and good performance in prediction accuracy can be shown.

Description

technical field [0001] The invention relates to the technical field of electric power system and automation thereof, and specifically relates to a method and equipment for multi-dimensional verification of grid-connected consumption information of renewable energy. Background technique [0002] To realize the sustainable development of energy, it is necessary to vigorously develop clean energy and open up a safe, clean and efficient road to sustainable energy development. The concept of Global Energy Internet came into being from this. The Global Energy Internet is an advanced stage of the development of a strong and smart grid. The core is dominated by clean energy, with UHV power grids as the backbone grid, extensive interconnection of power grids in various countries and continents, global allocation of energy resources, coordinated development of power grids at all levels, and various power sources. A strong smart grid that can be flexibly connected to users. The functio...
