Abstract

Now a day, Distributed Generation in Micro Grids plays a major role in extracting energy at convenient places and distributing with much ease and efficiently. Under such circumstances maintaining the Voltage levels at the point of distribution or point of common coupling (PCC) is an important task as demanded by the loads. Hence balancing or sharing the real and reactive power among the connected inverters is a challenging task. Droop control strategies play a better role in sharing the power among the inverters, although in many circumstances maintaining the node voltages at the system network is an arduous task. In order to improve the voltage level at the distribution points/PCC of the inverters a simple technique is presented in this paper, which measures the deviation of the voltage level at PCC and feed accordingly the reactive power to boost the voltage. However, the real power sharing is undisturbed. The method is schemed and simulated using MATLAB Simulink environment. The simulated results are encouraging that the intended technique has very good efficacy in maintaining the voltage level and agreed with the expected results.
