Big-data-based distributed power distribution network planning method

Abstract

The invention discloses a big-data-based distributed power distribution network planning method. The method comprises: historical data are collected and arrangement to form a large database for convenient storage and searching; and a power distribution network is planned, data in the large database are invoked in real time, and then the power distribution network is planned and set reasonably. According to the invention, at a load analysis stage, an electricity consumption tendency of a user is dug, an electricity demand prediction model of the user is perfected, dynamic market information is obtained actively, and thus a foundation is laid for project design planning. At a project planning design stage, making of decisions of distributed power supply site selection and project scale construction in the distribution network is helped and the power generation efficiency is improved. At an equipment operation stage, an operation and maintenance way is effective changed to realize intelligent operation and maintenance. And at a data integration stage, data sharing at all links in the distribution network is realized, a scheduling and management department is assisted in making decisions, energy losses are reduced, and the working efficiency and the energy utilization rate are improved.

Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to a large data-based distributed power distribution network planning method. Background technique [0002] Distributed power supply technology is an ideal way to make full use of renewable energy. It has the advantages of small investment, clean and environmentally friendly, flexible control, and high security. Indispensable essential supplement. [0003] However, with the diversification of construction subjects, the access of distributed power distribution network has great randomness, which brings serious challenges to the planning of distribution network. The reasonable arrangement of distributed power can delay or reduce the investment in power grid expansion. Reasonable application can reduce power grid loss, reduce power transmission and distribution costs, provide emergency backup energy or auxiliary services for the system, and improve the reliability and stability of...

Problems solved by technology

[0005] 1) The access of a large number of distributed power sources adds a large number of distributed generator nodes to the distribution network, which makes the planning analysis model more complex and brings scale and difficulty challenges to the existing planning methods and calculation tools. Finding the most It is more difficult to optimize the network layout scheme;

[0006] 2) The access of distributed power sources affects the load growth mode of the system, making the load forecasting of the po
