Description

一种配电网无功电压分层自组织控制模型及方法A hierarchical self-organizing control model and method for distribution network reactive power and voltage

技术领域Technical field

本申请涉及无功电压控制技术领域,尤其涉及一种配电网无功电压分层自组织控制技术领域。The present application relates to the technical field of reactive power and voltage control, and in particular to the technical field of hierarchical self-organizing control of reactive power and voltage in a distribution network.

背景技术Background technique

中低压配电网的无功电压问题对于降低线损,提高供电质量至关重要。The reactive voltage problem of medium and low voltage distribution networks is crucial to reducing line losses and improving power supply quality.

为了提高电压合格率,目前采用有载调压、无功补偿等方式提升电压合格率,但是现有的中心化控制方式,存在自组织控制性能差、对通信网络的依赖性强、网络安全问题突出等缺点,使得中低压配电的无功电压控制效果并不理想。In order to improve the voltage qualification rate, on-load voltage regulation, reactive power compensation and other methods are currently used to improve the voltage qualification rate. However, the existing centralized control method has poor self-organizing control performance, strong dependence on the communication network, and network security issues. Due to outstanding shortcomings, the reactive power and voltage control effect of medium and low voltage distribution is not ideal.

然而,去中心化、网络安全可靠性高等特点的区块链技术的出现,为中心化控制方式的不足,存储数据安全隐患提供了新的解决思路。区块链是一种分布式数据库,使用一串由密码学方法相关的数据区块,每个数据区块均包含过去一段时间内的所有数据信息,能够验证信息的有效性并产生区块,通过将此种技术应用于配电网无功电压控制中,利用区块链技术的特点,能够有效的解决中心化方式所带来的配电网自组织控制性差,尤其是网络安全隐患的问题。However, the emergence of blockchain technology with the characteristics of decentralization and high network security and reliability has provided new solutions to the shortcomings of centralized control methods and hidden data security risks. Blockchain is a distributed database that uses a series of data blocks related to cryptography. Each data block contains all data information in the past period of time. It can verify the validity of the information and generate blocks. By applying this technology to the reactive power and voltage control of the distribution network and utilizing the characteristics of blockchain technology, it can effectively solve the problem of poor self-organization control of the distribution network caused by the centralized approach, especially the problem of network security risks. .
