A fuzzy integrated virtual synchronous machine based STATCOM replicating synchronous condenser

This paper is presented with a STATCOM connected grid system operating as VSM injecting reactive power into the grid. The controller of the STATCOM is modeled with virtual inertia introduced for the static module to replicate a dynamic synchronous machine. In further advancements the conventional PI gain controller is replaced with FIS structure for more stability in the voltages and powers. The fuzzy system is modeled with 49 rule base for the generation of reference values. With these updates the STATCOM works as a synchronous condenser in connection with the grid system for reactive power compensation. Mathematical modeling and results with a simplified test system is achieved using MATLAB Simulink software controlled by powergui toolbox for generation of graphs.
