In recent years, tremendous increase in energy demand is being observed. To cope up with the increasing energy cost, achieve cleaner energy from renewable sources and to increase the reliability of quality energy supply Microgrids are playing a very important role. Smooth and reliable energy supply with a Microgrid consisting several types of distributed energy sources and several types of loads is of great challenge. This paper mainly focuses on comparative study between Droop Control of Inverters operating in Parallel in Islanded mode with conventional communication-based PQ Control of Inverters operating in Parallel. In this paper, control of parallelly operated Inverters with Droop Control and Conventional PQ Control has been studied by side-by-side comparison of simulation results of Voltage, Current, Active and Reactive Power Sharing and Frequency from MATLAB/SIMULINK. It has been observed that each of the above control techniques have their own advantage and disadvantages on which necessary study will be continued in due course.

摘要

In recent years, tremendous increase in energy demand is being observed. To cope up with the increasing energy cost, achieve cleaner energy from renewable sources and to increase the reliability of quality energy supply Microgrids are playing a very important role. Smooth and reliable energy supply with a Microgrid consisting several types of distributed energy sources and several types of loads is of great challenge. This paper mainly focuses on comparative study between Droop Control of Inverters operating in Parallel in Islanded mode with conventional communication-based PQ Control of Inverters operating in Parallel. In this paper, control of parallelly operated Inverters with Droop Control and Conventional PQ Control has been studied by side-by-side comparison of simulation results of Voltage, Current, Active and Reactive Power Sharing and Frequency from MATLAB/SIMULINK. It has been observed that each of the above control techniques have their own advantage and disadvantages on which necessary study will be continued in due course.
