Title  Analyze of Dynamic Voltage Restoration with Minimum   Energy Injection

Abstract
With the continuous development of interconnected power systems and the extensive use of power electronic devices, the current energy issues, particularly the voltage sag problem becomes more prominent.The main strategy of current research for the compensation of Dynamic Voltage Restorer (DVR) is improving the minimum energy strategy to achieve optimal purpose and improve the controlling effect.
This paper analyzes the component of DVR working structure .Apart from that,this paper mainly analyzes  minimum energy compensation laws and strategies and uses simulation software to programme to gain the minimum energy compensation strategy.To verify the minimum energy strategy, this paper discusses the use of MATLAB/SIMULINK simulation model-related issues ,selects the main structure and sets parameters of dynamic voltage restorer.Finally,the simulation uses D-q detection method which is based on compensation method.The simulation model verify the performance of minimum energy .The minimum energy method can reduce power consumption is fully verified by comparing with output power of  complete voltage compensation method’s dynamic voltage restorer.
