MGs provide flexibility, reduce the main electricity grid dependence and contribute to change the large centralized production paradigm to local and distributed generation. However, such energy systems require complex management, advanced control and optimization. Moreover, the power electronics converters have to be used to correct energy conversion and interconnected through common control structure is necessary. Classical Droop Control system is often implemented in microgrid. It allows to the correct operation of parallel voltage source converters (VSI) in grid connected as well as islanded mode of operation. However, it requires complex power management algorithms, especially in islanded microgrids, which balances system, improves reliability. The novel reactive power sharing algorithm is developed, which takes into account the converters parameters as apparent power limit and maximum active power. The developed solution is verified in simulation and compared with other known reactive power control methods.

The main objective of this paper is to improve power quality. In this project, the economic dispatch and weekly operation planning are the methods of Microgrid control where the main objectives are to minimize fuel cost and CO2 emission. The objective of having Microgrid is discussed. The main components of Microgrid and the technique on how the Microgrid central controller was developed. to control the voltage and frequency the Microgrid controller managed in both grid connected and islanding mode as well as maintained them within mandatory operational limit of respective operation code. A microgrid comprises distributed generation, energy storage, loads, and a control system that is capable of operating in grid-tied mode and/or islanded mode. An active power loss is also significantly reduced. By using the simulation results we can study the Microgrid system and also to demonstrate the workability of the concept.
