An innovative power calculation method to improve power sharing in VSI based Micro Grid

Micro Grid (MG) is a local distribution system that feeds load by produced power of DGs; these DGs are controlled by controllers that often are wireless control systems. All of these methods need to calculate power to make decision whether produced power, to keep system stable, is enough or not. This method based on droop method, this means that new method is one of wireless control method. In this paper a novel control method is proposed to calculate power faster and easier than old method. In this method Low Pass Filter that used to terminate high frequency components of power phrase removed, and replaced by some math operations. This method is faster and has less fluctuation of power than old method. Analyses and simulated result are derived from two inverters that connected in parallel together and feed load. By comparing result of new method and conventional method advantages of new method are shown.
