Voltage Support and Reactive Power Control in Micro-grid using DG
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 7
Abstract
Distribution Generators(DGs) are the renewable energy resource which can be connected to the grid. When it is connected to the grid it should be operated with controlled voltage and reactive power control. And in autonomous mode(i.e disconnected mode) it should operate in backup generation mode. These DGs are connected towards the micro grid operation. The proposed control system facilitates flexible and robust DG operational characteristics such as active/reactive power (PQ) or active power/voltage (PV) bus operation in the grid- connected mode, regulated power control in autonomous micro-grid mode, smooth transition between autonomous mode and PV or PQ grid connected modes and vice versa, reduced voltage distortion under heavily nonlinear loading conditions, and robust control performance under islanding detection delays. Evaluation results are presented to demonstrate the flexibility and effectiveness of the proposed controller
