Description

technical field [0001] The invention relates to the field of power grid management, in particular to a power grid planning auxiliary system. Background technique [0002] Grid planning, also known as transmission system planning, is based on load forecasting and power supply planning. Power grid planning determines when and where to invest in what type of transmission lines and the number of circuits to achieve the required transmission capacity within the planning cycle, and to minimize the cost of the transmission system on the premise of meeting various technical indicators. The city is the main load center of the power system. Whether the urban power grid operates well depends on whether the planning and construction of the urban power grid are scientific and economically reasonable. For power supply companies with huge fixed assets, urban network planning is crucial to the survival and always play a decisive role in development. The power supply enterprise is not only...

Problems solved by technology

[0004] At the same time, for the medium and long-term optimization planning problems of the power grid, planning functions (such as linear functions, neural networks, fuzzy methods, decision trees, etc.) and planning graphs are often used in power grid planning rule types, but these types are based on experience and the theoretical basis is weak. , especially for grid group planning, there is no general planning rule type
