Study On Adaptability Of Xinjiang New Energy And Distribution Grid

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.
