    Performance study of roof top wind solar microgrid system in isolated mode of operation
    (Institute of Electrical and Electronics Engineers Inc., 2014) Gaonkar, D.N.; Sabhahit, N.S.; Raghavendra, P.
    The increasing interconnection of distributed generation sources of diverse technologies to low voltage grids introduces considerable complexity in its operation and control. The concept of the microgrid is emerging as a solution to this and also to take full advantage of the potential offered by distributed generation resources. In this paper the performance study of a roof top wind solar hybrid microgrid in isolated mode of operation has been presented. The developed 10 kW microgrid consists of two wind turbine of 3.2 kW each and a PV system of 3.6 kW peak. The microgrid is interfaced to the load through a voltage source inverter. The performance of wind system in the developed microgrid has been investigated under different input conditions and practical results have been reported in this paper. © 2014 IEEE.

    Frequency and voltage droop control of parallel inverters in microgrid
    (Institute of Electrical and Electronics Engineers Inc., 2016) Chethan Raj, D.; Gaonkar, D.N.
    The distributed generation units are connected to microgrid through an interfacing inverter. Interfaced inverter plays main role in the operating performance of microgrid. In this paper, interfaced parallel inverter control using an P-F/Q-V droop control was investigated, when microgrid operated in islanded mode. In islanding mode the inverter droop control should maintain voltage and frequency stability. The droop control for parallel inverters is implemented and the proportional load sharing is obtained from each individual inverter. Droop control of inverter is simulated on Matlab/Simulink, the results indicate droop control has a significant effect on balancing the voltage magnitude, frequency and power sharing. © 2016 IEEE.
