The invention provides an optimization method for feeder line and distributed power supply planning, and the method comprises the steps: firstly obtaining a plurality of groups of feeder line and distributed power supply planning schemes, constructing an initial planning set, obtaining planning constraint parameters, and generating a planning constraint model; based on the initial planning set and the planning constraint model, generating a feeder construction cost model, a distributed power supply construction and maintenance cost model and a network loss model, and further generating a planning overall evaluation model for evaluating the advantages and disadvantages of the planning schemes; carrying out traversal optimization on the planning set according to the basic thought of a teaching and learning algorithm in combination with a local search strategy, so that reasonable planning can be effectively carried out on the access problem of a to-be-built feeder line and a distributed power supply, and the minimization of the construction expenditure and the system line loss is realized.
Description
technical field [0001] The present application relates to the technical field of intelligent optimization of power systems, in particular to an optimization method for feeder and distributed power planning. Background technique [0002] The power system is closely related to people's daily life. In the foreseeable future, there will be a large number of feeder extensions and grid planning for distributed power access. As an important part of power grid construction, whether the power grid planning is scientific or not directly affects the power supply quality of the power grid, and the planning and construction of the power grid involve many factors, which have caused many obstacles to the planning and construction of the power grid. [0003] In the existing technology, the constraint conditions that contain more feeder expansion and distributed power access problems are implicitly included in the coding and decoding rules of the designed solution, and a certain anthropomorp...
