The power industry is undergoing significant changes due to apprehensions about traditional energy prices and greenhouse emissions due to the use of fossil fuels. As a solution, numbers of Distributed Energy Resources (DERs) are connected to the grid. Accumulation loads and DERs constitute a microgrid as a small-scale grid compared to a conventional grid. In a conventional grid, regulation of voltage and frequency are controlled by the speed variation of alternators interconnected to the grid. As the usage of DERs in power networks grows, additional challenges emerge, like the frequency and voltage regulation problems. However, the voltage and frequency must be regulated independently of the main grid if the microgrid is detached from the main utility grid. In this paper, the deviation in voltage is regulated by utilizing a Genetic algorithm (GA) to optimize the droop coefficients. The work is carried out for various loads to regulate voltage variation and reactive power-sharing, and the responses are presented. The results for voltage deviations with and without GA optimizations are also presented.
