A recap of modern power grid control systems

Abstract

Wind power plants (WPPs) and photovoltaic power plants (PV systems) are the most popular types of renewable power plants (RPPs) in the formation of modern power grids. A lot of modern power grids have already been interconnected with WPPs. Control methods have been proposed and (or) developed in the existing research. However, it has been found that the existing literature does not clearly state the exact point where these control methods should be applied in the modern power grid. Also, till today, the existing literature does not look at and clearly define the difference between the control methods for the point of connection (POC) and the point of common coupling (PCC). In this article, the control methods applied in modern power grids are discussed, and the linkage between them has been described clearly.
