Bidirectional Converter Connecting the Energy Storage System to the DC and AC Grid

Nguyen The Vinh

Abstract


A new built-in DC/DC/AC converter has the structure and function of linking between the DC and AC microgrid including renewable source and load,and the storage system for the microgrid system. Electrical energy consumption is increasing, as does the need to increase the power supply. The microgrid is studied with the necessary objective of the energy security of the country in the near future and increases operational flexibility, minimizing loss during conversion and investment in the microgrids. In this proposal, a multi-function converter is used to convert un-bidirectional and bidirectional energy, it connects storage system, DC/AC converter connects to AC load, DC and AC microgrid. The proposed converter is modified from a SEPIC converter with a pulse transformer, combined with the Buck-Boost and full bridge converter. The converter has many advantages such as high voltage gain, non-inverting output, constant input current, high efficiency and lower voltage stress on the switches. The hybrid converter connected to the microgrid can flexibly provide power loads from DC and AC grid, therefore, system reliability is likely to be improved alternative sources of supply. System expansion is simpler. The results of the converter were carried out by OrCAD and experiment in the laboratory.
