COMPENSATION OF VOLTAGE VARIATIONS IN DISTRIBUTION SYSTEM DURING FAULT CONDITION BY USING SEPARATE ENERGY STORAGE DEVICE BASED DVR.

The increased asset utilization, facilitates the penetration of renewable sources and improves the exibility, reliability and efficiency of the grid, Separate Energy Storage Devices (SESD) technology has been progressed. SESD Technology has the potential to bring real power storage characteristic to protect consumer's loads from the grid voltage uctuations like Long and Short term Voltage variation conditions. This project deals the Design of Decision making Switch and operation principle of the SESD based Dynamic Voltage Restorer (DVR) and its design is based on simple PI control method to compensate voltage Fluctuations. The principle of SESD based DVR is analyzed in this work. The performance of the SESD is validated through simulations using MATLAB SIMULINK and the results reveals that the SESD can be a useful DC source for the DVR. [ABSTRACT FROM AUTHOR]
