Problems solved by technology
When optimizing distribution network reliability improvement measures based on optimization modeling methods, due to the variety and quantity of large-scale distribution network reliability improvement measures, and involving a large number of basic parameters and operating parameters, it is often due to The scale of the problem and the number of decision variables are huge, which makes the solution easy to fall into local optimum, or even fail to converge, and the accuracy of screening is low
When optimizing the distribution network reliability improvement measures based on the method of program evaluation, it is first necessary to list the possible grid improvement programs, and make technical and economic comparisons of the alternatives by constructing an index system or an optimal model, which is widely used in engineering practice; However, existing scenario evaluation-based methods have low modeling accuracy and their screening accuracy is low
