Modeling of Solar Farm as a FACTS Device for Power System Stability

The increase in power demand and use of various types of electrical equipment has a great impact on the stability of the system. Whenever there is switching, loss of load line or any type of fault there is a change in the behavior of the system and these phenomena affects the stability of the system. For the stability analysis of a system two kinds of stability analysis is performed small signal stability study (Steady State Stability and Dynamic Stability) and large signal stability (Transient Stability) study. In this work we will improve the transient behavior of the Grid with the help of Photovoltaic based Solar Farm which will act as FACTS device. The output of PV cell is DC which is an important part of storage system of FACTS device / controllers. In this work we will make an array of PV cell which will act as DC source to the converters and by applying suitable control algorithm we will control the output of converter.
