Resumo: This work presents a bibliographic review on some of the control techniques present in the literature aiming to emulating the electrical and mechanical characteristics of synchronous machines in inverters, and it also proposes a control strategy aiming to do inverters work as synchronous machines. This strategy is defined at this work as VSM converter. The studied techniques are classified into certain groups according to the common characteristics among them. Some of these techniques are simulated aiming to evaluate their dynamic responses and to determine the level of influence of their control structures in the obtained responses. After the bibliographic study, a control technique that allows inverters to work as if they were synchronous machines is proposed, assuming the characteristics and properties that these machines have. The development of each control block that composes the VSM converter is presented, as well as a methodology that allows these VSM converters to operate isolated, in parallel, sharing the active and reactive demanded power by the load and connected to the electrical grid, without the need of control switching between grid-connected and isolated modes. Simulated and experimental results prove the developed theory.
