Nonlinear Control of a Static Synchronous Compensator

With the rise of environmental awareness, many countries pay more attention on energy resources, especially for electricity, because it is already indispensable in the high-tech society. Therefore, it is the most basic policy to effectively provide stable power to the load side. This paper adopts the most popular device, called a static synchronous compensator (STACOM), to obtain the reactive compensation due to the power loss in the electrical system. Since a STATCOM is a nonlinear system, one applies the sliding mode control to a STACOM. The simulation results show that the reactive power compensations in the stable operation can be confirmed.
