Analysis of Wind Power Generation System in Micro-Grid by using DSTATCOM

This paper work presents an improved control strategy for a DC Grid based multiple parallel wind power system by eliminating the necessity for voltage and frequency synchronization. The Permanent Magnet Synchronous Generator is considered in this paper since it doesn't require a dc excitation framework that will expand the plan many-sided quality of the control equipment. Separate controllers are proposed for the inverter when grid is in grid-connected and islanded modes of operation. Model predictive control algorithm is employed for the higher transient performance with reference to the change within the operating condition for the inverter operation. A separate controller has been developed for the turbine to take care of the constant power and to mitigate the variation error. Performance of the proposed micro grid in grid connected operation for inverter failure, connection of AC/DC Grid and also islanded mode of operation is evaluated.
