Abstract

The invention discloses a power distribution network distributed state sensing and optimizing method based on a blockchain technology. The method is used for replacing a traditional optimization method on the premise of reliable communication. A sparse communication network is constructed through blockchain nodes dispersedly arranged in a power distribution network; distributed sensing of the operation state of the power distribution network is realized by adopting an estimation mode and depending on interaction of a small amount of measurement data and information, the model is convexly relaxed by performing decentralized processing on an optimization model and combining a second-order cone programming convex relaxation method, and finally, full-distributed solving of the problem is realized by utilizing a cross direction multiplier method. According to the method, a blockchain system not only can complete the existing functions of power transaction, demand response and the like, butalso can realize the distributed optimization of the operation state of the power distribution network under the condition of communication failure, thereby effectively improving the operation reliability and economy of the power distribution network.

Description

technical field [0001] The invention relates to an electric power technology, in particular to a distributed state perception and optimization method of a distribution network based on block chain technology. Background technique [0002] Distribution network reliability refers to the distribution network itself that directly supplies power to users or distributes electric energy and the reliability of power supply to users. In the distribution network reliability evaluation, the analysis process of the evaluation can be composed of the following steps: (1) select the operating state of the system; (2) estimate the state of the system, mainly by performing power flow calculations to see if There are situations such as over-limit, overload, etc.; (3) Calculate each reliability index. [0003] At present, with the development of distributed power generation technology and the increasingly serious environmental pollution problems, the introduction of distributed power generati...
