Analysis of D-SVC and D-STATCOM in Microgrids with Wind Farm Integration

Over time, Networks are getting complex, and stability issues are more and more likely to arise. Overall, the problem of voltage instability increases as various random energy sources such as solar, wind, etc. are connected to the network.; Grid control is the most notable matter. To realize optimal grid electricity performance, it is essential to control the flow of reactive power in the grid. Unbalanced reactive power occurs when a system fails, is extremely loaded, and fluctuates in voltage. Reactive power dynamic can be restored by connecting a device to the transmission line that can create or absorb reactive energy according to the needs of the system. D-FACTS equipment is a useful source of reactive power (Distributed Flexible AC Transmission System). The D-FACTS families' most well-known compensation methods are Distributed Static Var Compensation (D-SVC) and Distributed Static Synchronous Compensation (D-STATCOM). We investigate the impact of D-SVC and D-STATCOM on improving the voltage fluctuation stability of distribution networks with wind power distribution and variable load in this paper. The dynamic behavior of both devices was observed through simulations performed with MATLAB/Simulink. A comparison of simulation results between grids without D-FACTS and grids with D-FACTS was presented in this article.
