【摘要】：随着智能电网理论研究及实践的深入,智能配电网作为智能电网中双向电力流和双向信息流集中体现的环节,对智能电网的发展有着不可忽视的作用。随着分布式电源的逐步推广和应用,未来智能配电网将成为分布式电源接入电网的主要接口。同时,为了保证智能配电网的可观测性,大量的智能电子设备将引入智能配电网。智能配电网的这些新的变化将会给配电网带来大量的量测信息,如何建设符合智能电网和智能配电网发展需求的集成信息系统,对智能配电网安全、稳定、优化运行具有十分重要的意义。目前对智能配电网信息集成的研究主要可分为对涵盖了智能配电网的整个智能电网的信息系统的总纲性研究和对配电网中部分环节或部分高级应用系统之间的信息集成共享研究。前者着眼于整个智能电网的发展趋势,没能对智能配电网进行细致地分析；而后者仅局限于配电网中的部分量测信息,不能满足整个智能配电网的量测信息集成要求。本论文综合这两种研究思路,基于智能电网概念模型理论,研究智能配电网集成量测体系相关理论和方法。论文首先引入了智能电网概念模型及域的概念,总结了智能配电网概念模型,在此基础上提出智能配电网集成量测体系概念,并详细分析了集成量测体系的功能需求和特点,及其对智能配电网发展和建设的意义。智能配电网集成量测体系是对配电网中信息流动过程的描述。论文总结了集成量测体系中对应用信息流的分析方法——“PIC”法以及应用对信息流要求的具体分析方法——“五视图”法,并对“配电电压无功控制”应用给出了示例应用分析。在前面研究的基础上,论文给出了智能配电网集成量测体系参考架构,并对其进行了详细分析。此外,论文还对智能配电网信息网络规划算法进行了研究。针对信息网络可生存性要求,根据配电网的实际情况,运用N-1准则提出了相应的规划模型,并设计了考虑N-1约束的启发式规划算法,算例对比验证了算法的可行性。
[Abstract]:With the deepening of the theoretical research and practice of smart grid, smart distribution network as a two-way power flow and two-way information flow in the smart grid embodied in the link. With the gradual promotion and application of distributed power generation, smart distribution network will become the main interface of distributed generation to the power grid in the future. At the same time, in order to ensure the observability of smart distribution network, A large number of smart electronic devices will be introduced into the smart distribution network. These new changes in the smart distribution network will bring a lot of measurement information to the distribution network, and how to build an integrated information system that meets the needs of the development of the smart grid and the smart distribution network. It is of great significance to the security, stability and optimal operation of smart distribution network. At present, the research on the information integration of smart distribution network can be divided into two parts: the general outline of the information system of the whole smart distribution network which covers the smart distribution network and the research on some links or part of the advanced application system in the distribution network. Research on information integration and sharing. The former focuses on the development trend of the whole smart grid. The smart distribution network can not be analyzed in detail, but the latter is limited to part of the measurement information in the distribution network, which can not meet the requirements of the whole smart distribution network measurement information integration. Based on the conceptual model theory of smart grid, this paper synthesizes these two research ideas, and studies the relevant theories and methods of intelligent distribution network integrated measurement system. Firstly, the concept model and domain concept of smart distribution network are introduced, and the concept of intelligent distribution network integrated measurement system is put forward, and the functional requirements and characteristics of integrated measurement system are analyzed in detail. And its significance to the development and construction of smart distribution network. The intelligent distribution network integrated measurement system is the description of the information flow process in the distribution network. This paper summarizes the analysis method of the applied information flow in the integrated measurement system-"PIC" method and the "five views" method, which is the concrete analysis method of the application information flow requirement. The application of "distribution voltage and reactive power control" is analyzed. Based on the previous research, the reference architecture of intelligent distribution network integrated measurement system is presented and analyzed in detail. In addition, the paper also studies the intelligent distribution network information network planning algorithm. According to the information network survivability requirements, according to the actual situation of the distribution network, using the N-1 criterion, the corresponding planning model is proposed. A heuristic programming algorithm with N-1 constraints is designed, and the feasibility of the algorithm is verified by an example.
