In order to study the development prospect of DC system, this paper discusses the reliability of DC distribution network. First, this paper introduces the characteristics of DC distribution system, and summarizes the main structures. Then, the reliability assessment model of power electronic equipment is established, and the reliability parameters of redundant components are calculated by using k/n(G) and Markov model. Moreover, the reliability index of DC distribution network is calculated based on the minimum cut set method. Finally, the IEEE RBTS Bus5 system is modified to calculate and compare the reliability indices of different distribution networks. The results show that the reliability of DC distribution network is limited by the reliability of equipment, and the reliability of DC system can be improved with the increasing proportion of DC load. In the future, with the improvement of power electronic equipment and the increase of DC load, the reliability of DC distribution network will be better than that of AC distribution network.","PeriodicalId":142885,"journal":{"name":"2018 China International Conference on Electricity Distribution (CICED)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125942362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How to achieve energy efficiency, environmental protection has become a global hot issue. Distributed energy supply system will become an important and effective way to realize the coordinated development of economy and energy. In the design of distributed energy supply system, the characteristics of distributed energy supply system are often not fully taken into account, which results in too large capacity selection of the unit, which can not reflect the superiority and benefit of the distributed energy supply system. Therefore, it is more important for the success of the project to carry out accurate load forecasting of cooling heating and power load.

Based on the linearized model, the relation between the auxiliary damping torque (ΔMD2) provided by UEL and the pertinent parameters of UEL is extracted. With the damping torque analysis (DTA) technique, it is shown that the dynamic stability of the system can be affected by the value of the proportional gain (KP) and the internal gain (KI) of UEL.

An affine nonlinear model of NPC-SAPF is established in the synchronous d-q-0 frame. Applying state feedback linearization method to the affine nonlinear model, a linearized and decoupled NPC-SAPF mathematical model is obtained. The globally asymptotically stable NPC-SAPF control system is built by choosing an appropriate Lyapunov candidate function and making sure that the function satisfies the required properties of Lyapunov stability theory.
