An efficient energy management system for a small-scale hybrid wind-solar-battery based microgrid is proposed in this paper. The wind and solar energy conversion systems and battery storage system have been developed along with power electronic converters, control algorithms and controllers to test the operation of hybrid microgrid. The power balance is maintained by an energy management system for the variations of renewable energy power generation and also for the load demand variations. This microgrid operates in standalone mode and provides a testing platform for different control algorithms, energy management systems and test conditions. A real-time control is performed by rapid control prototyping to test and validate the control algorithms of microgrid system experimentally. The proposed small-scale renewable energy based microgrid can be used as a test bench for research and testing of algorithms in smart grid applications.

Environmental conditions, electrical modeling and developments in industries led to new power generation epoch where fat section of power required for load section is fed through extensive induction of distributed resources generally known as distributed generation [DG].  Distributed generation reduces the risk of environmental pollution and distance criterion posed from conventional power generation. This paper presents grid integration scheme of distributed generation using five-level cascaded H-Bridge (CHB) inverter. Reference currents used to produce pulses for switches in CHB are generated using a simple control strategy. Performance of the system was evaluated when only active power is fed from distributed generation to grid and also when both active and reactive powers were fed to grid from distributed generation. Proposed system was developed using MATLAB/SIMULINK software and results are presented.

The ability to the heap is controlled by changing the obligation cycles of PWM pulses. The pulses are synchronized with supply phase by zero detecting point. III. HARDWARE SYSTEM A. Labview LabVIEW programs are called virtual instrumentation (VI) on the grounds that their appearance and activity mimic physical instruments, for example, oscilloscopes and Multi Meters. LabVIEW is a graphical programming code used to get, control and store information. It is conceivable to speak with equipment by utilizing DAQ, RS232 interface. At whatever point the serial port is prepared to transmit information, it brings information to equipment cushion. The controller gets information through the interfacing devices and the motor is controlled by changing the pulse width modulation.
