Embodiment Construction

[0068] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto. The implementation flowchart of the present invention in the embodiment is as appended figure 1 shown.

[0069] A method for evaluating the operating state of an active distribution network, comprising the following steps:

[0070] 1. Establish an evaluation index system for the operation status of active distribution network: Based on the principle of systematic, objective, scientific and practical index system construction, divide the operation status of active distribution network into emergency, demand and There are five operating states of recovery state, abnormal state, normal state and optimized state, and the health of the target active distribution network is evaluated from six aspects: safety, reliability, quality, economy, adaptability and networking. Evaluate to ...

Abstract

An active power distribution network operation state evaluation method, comprising the following steps: constructing an active power distribution network operation state evaluation index system; unifying the evaluation indexes; determining an optimized combination weight; performing distance comprehensive evaluation on the operation state of each evaluation object, and giving a relative advantageand disadvantage sequence of the comprehensive operation state of each evaluation object; and performing attribute interval comprehensive evaluation: an attribute measurement interval matrix needing to be constructed when the operation state of the active power distribution network is analyzed by using an attribute interval algorithm, and determining a final evaluation level by using a level characteristic value method. The method has the advantages that 1, an evaluation index system for representing the operation state of the active power distribution network is constructed; 2, combining a subjective weight based on an analytic hierarchy process and an objective weight based on a variable coefficient method by adopting least square optimization; and 3, an attribute interval algorithm is utilized, the fuzziness characteristic in the operation state of the active power distribution network is fully considered, complete membership information is considered, and finally, the obtained comprehensive evaluation result of each index is scientific and effective.

Description

technical field [0001] The invention relates to a method for evaluating the operating state of an active distribution network based on combined weight, comprehensive evaluation of distance and attribute interval algorithm, belonging to the field of electrical engineering. Background technique [0002] The development of today's society is inseparable from electricity, and it is urgent to realize the self-healing control of the distribution network to meet the increasing requirements of power users for the power supply of the distribution network, and mastering the operation status of the distribution network is a prerequisite for realizing self-healing control. [0003] Self-healing control can endow the active distribution network (Active Distribution Network, ADN) with stronger self-healing ability, so that it can always run in a good state. The operating state of the active distribution network will be affected by its environment, and its operating environment is very com...
