An Overview of Frequency and Power Changes Quantifition in a Microgrid; Multiply Distribution Generators

The increase in the global warming level, the distribution of generators based on renewable energy, is increasing to play the dominant role in electricity production. Distribution generators based on solar energy (photovoltaic) and wind turban are gaining significant motivation in the future. Microgrid is a new energy distribution techniques system that is connected to renewable energy integration. It consists of many distributed generators that interface to the grid through a power electronic converter, has elevated anxiety about safe operation, and protects the equipment. Several control techniques have been used to attract the stability of the Microgrid for proper load sharing. While parallel converter has been controlled to deliver desired real power and reactive power to the system. The native signal is being used as feedback to control converters, since in a real system the diffidence between the converter may make the inter-communication impossible. Real and reactive power sharing can be achieved by controlling two autonomous quantities, frequency, and fundamental voltage magnitude. The review and the approach of power-sharing control principles and the comparison of their respective advantages and disadvantages.
