Problems solved by technology

[0003] At present, scholars at home and abroad have little research on the evaluation index system of incremental distribution network planning. The advantages and disadvantages of distribution network planning and construction schemes are evaluated, but the influence of reliability, safety, green and low-carbon characteristics in the evaluation of incremental distribution network planning is rarely considered comprehensively; in addition, incremental distribution networks include Distributed power supply, distribution network and load users are the three parties investing in the main body. The traditional distribution network planning evaluation index system is difficult to apply. It is urgent to study the incremental distribution network planning evaluation index system.
[0004] In addition, since the evaluation objects of incremental distribution network planning include the source-network-load tripartite stakeholders, and the planning evaluation objectives involve economy, reliability, safety, and low-carbon environmental protection, etc., the evaluation indicators that can be referred to are wide and numerous , the indicator evaluation information will also overlap
In addition, the existing technology provides some incremental distribution network value evaluation schemes, which try to accurately obtain the actual value of the incremental distribution network, but such evaluation results are too subjective and poor in objectivity; and the considerations and measurement methods are often Too single, the evaluation results are quite different from the actual results
