Abstract With the development of intelligent distribution networks and the increasing demand for new energy access, the isolated bidirectional dc-dc converter has become a key link in modern energy transformation systems. In order to realize the functions of electrical transformation and electrical isolation of dc voltage, this paper proposes a structure of isolated bidirectional dc-dc converter, and analyzes it in detail. The proposed isolated bidirectional dc-dc converter can not only realize voltage transformation, but also have voltage regulation and fault isolation functions. Finally, based on the MATLAB/Simulink simulation platform, the proposed isolated bidirectional dc-dc converter topology is built and verified by simulation. The structure of isolated bidirectional dc-dc converter not only has the functions of voltage transformation and electrical isolation, but also has fault isolation, power flow control and other functions.

Automation Control

The accsess of large numbers of new energy and the difference of application requirements make information more huge and complex, different application system and different grid link has also a different protocol standards,All these make the visual display of information, unified modeling for power grid automation become complicated and trival. This article according to analysis the power grid stability and control theory, from the power grid stability and controlling ,the needed information and IEC61968 / IEC61970 / IEC61850 and other international standards are analyzed, and propose a power network information classification method, and get a power information classification, accord with smart grid construction and new energy access requirements. It can effectively direct building of power automation control model, control information interaction. Provide foundation support for grid unified modeling and the method of unified describe model.

Constrained Programming

This paper raises a model which concerns about spinning reserve capacity of output and predicted error based on chance-constrained programming. The distribution function is established on the load demand of electric vehicles. Considering the complementarities of electric vehicles and small hydro and wind power generations, this paper constructs a dispatch model on the participation of electric vehicles in reserve capacity and peak regulation. Joint operation of different units in the system achieved by genetic algorithm examines the influence from joint dispatch of electric vehicles and small hydro and wind power generations on spinning reserve capacity and peak regulation plan, setting different values of confidence to make comparison of electric charge in the entire system. According to the real operation statistics of an electric company in a certain province, the reliability and accuracy of the model was guaranteed.
