Study of Reactive Power Control in Microgrid
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 7
Abstract
In this paper several newapproaches in controllingof reactive power in microgrid is discussed. First, this paper theoretical analyzes kinds of reactive and harmonic current detection methods; then the reactive power control by means of a reactive power/frequency droop control strategy is studied in an islanded microgrid. In a low voltage microgrid, due to the effects of nontrivial feeder impedance, the conventional droop control is subject to the real and reactive power coupling and steady-state reactive power errors. So the conventional reactive power droop control can be improved with zero steady state sharing error, just like the real power sharing through frequency droop control. Tertiary a coordinated control of Distributed Generators (DG) and Distribution Static Compensator (DSTATCOM) in a microgrid is proposed. And at last a solution for data acquisition and control of MicroGrid using wireless technique (ZigBee @ 2.4 GHz), that manages the reading of various electrical parameters in different DG’s, is presented.
