新疆具有丰富的风能、太阳能和天然气等资源，近年来随着“电化新疆”工程的推进，对天然气、风电、光伏的开发力度加大，新疆的煤炭、石油在新疆能源生产的主体地位下降，能源生产结构逐步呈现多元化发展。新能源及分布式电源接入配电网络的建设已经逐项开展，在为配电网带来容量扩展的同时，也为配电网络的稳定性和安全性带来挑战，对配电网接纳新能源及分布式电源能力进行适应性评价并以此为基础对其进行改进以增强适应性，将具有十分重要的意义。 为此，论文提出了针对新疆新能源及分布式电源接入配电网的适应性研究，进行的主要工作如下： 首先，分析了新疆电网的基本情况，调研了新疆新能源与分布式电源在未来15年内的规划与需求。 其次，从短路电流水平、电压稳定性和调度运行特性等方面研究了新能源与分布式电源对电网的影响作用，构建了电网的适应性评价指标体系； 接着，根据新能源和分布式电源的具体概况，评估配电网的适应性，在此基础上，提出配电网络改造原则、技术方案。 最后，以新疆配电网络为例，实施为提高配电网接纳新能源和分布式电源适应性而进行的改造，并与原有网络适应度比较，验证本文改造方法的有效性。 论文研究结果可为同类区域配电网接入新能源电源的适用性评价提供理论参考和依据。

Xinjiang has abundant resources such as wind energy, solar energy and natural gas. In recent years, with the promotion of "electrified Xinjiang" project, the development of natural gas, wind power and photovoltaic is intensified. The main status of coal and oil in Xinjiang is declining in Xinjiang, and the energy production structure is gradually diversified. The construction of new energy and distributed power distribution network has been carried out item by item, which brings capacity expansion to the distribution network, also challenges the stability and security of the distribution network. It also improves the adaptability of the distribution network to accept new energy and the ability of distributed power supply, and improves it on the basis of this. It will be of great significance. For this reason, the paper puts forward the adaptability research of Xinjiang new energy and distributed generation access to distribution network. The main work is as follows: Firstly, the basic situation of Xinjiang power grid is analyzed, and the planning and demand of new energy and distributed generation in Xinjiang in the next 15 years are investigated. Secondly, the influence of new energy and distributed power on power grid is studied from the aspects of short circuit current level, voltage stability and dispatching operation characteristics, and the adaptability evaluation index system of power grid is constructed. Then, according to the specific situation of new energy and distributed power, the adaptability of distribution network is evaluated. On this basis, the principle and technical scheme of distribution network transformation are put forward. Finally, taking the Xinjiang distribution network as an example, the reform is carried out to improve the adaptability of new and distributed power sources in the distribution network, and compared with the original network to verify the effectiveness of the modified method. The research results can provide a theoretical reference and basis for the applicability evaluation of similar regional distribution network to access new energy sources.
