Problems solved by technology

The output stability and adjustable controllability of distributed power generation are poor, and the higher the penetration rate, the greater the risk of safe and stable operation of the power grid
User interaction is spontaneous and random, making it difficult to predict changes in load characteristics, and without reasonable guidance will affect the safe and stable operation of the power grid

Embodiment Construction

[0017] The efficiency evaluation index processing scheme of the smart distribution network is based on the collected smart distribution network planning data and operation data, and on the basis of calculating the reliability index, economic index, cleanliness index and interactive index of the smart distribution network. Efficiency evaluation index value of smart distribution network. The specific evaluation process is as follows:

[0018] 1) The reliability evaluation module is based on the average number of power outages of users, the average time of power outages of users, the proportion of power outages, the average installation capacity of line segments, the proportion of equipment that does not stop power failure during failures, and the weight of evaluation indicators, such as Nanjing Hexi New City Power Distribution Network reliability is 0.1 times, 1.5 minutes, 0.3%, 4kVA, 100%, and the network reliability is 4.3629 through weighted average calculation; The distribu...

Abstract

The invention provides a method for processing high-efficiency evaluation indexes of a smart distribution network. The method comprises the following steps: automatically collecting and processing data of the smart distribution network; considering real-time data and historical data, planning data and operating data; calculating and generating high-efficiency comprehensive evaluation indexes of the smart distribution network from the indexes of representing four aspects, namely reliability, economical efficiency, cleanability and interactivity of the smart distribution network. By adopting the method for processing the high-efficiency evaluation indexes of the smart distribution network disclosed by the invention, the real-time data and the historical data, the planning data and the operating data can be automatically coordinated under the condition of absence of human intervention; high efficiency of the smart distribution network is estimated from the four aspects including the reliability, the economical efficiency, the cleanability and the interactivity; the method has network adaptivity.
