The fundamental changes in power systems have led to an increased complexity in their operation and control. Wide area monitoring systems (WAMS) are considered as a key solution in order to deal with these challenges. In this paper, a general description of WAMS is presented along with a literature review on the topic. Emphasis is given on documenting real up to date applications of WAMS in the European power network. Moreover, wide area damping control systems for power system oscillations are also presented. A description is provided of two innovative WAMS combined with damping control using FACTS devices and Battery Energy Energy Storage Systems (BESS) that are currently implemented in the European network.

“…Also, hysteresis current control and instantaneous power theory methods can be applied to inverter control to provide better performance as well [24]. Also, to achieve system stability, the cascaded-mode control scheme is better than the standard vector control scheme under abnormal conditions [25]. For producing a new method for modelling, simulation and also to detect the transient nature of PV module a rated power in KW's containing PV generator and singlephase grid-connected inverter is considered [13].…”

The fast depletion of fossil fuels has created a quest for alternate energy sources to take care of the increased load demands Solar energy is the most abundant form of renewable energy available to us than any other source of energy. The photovoltaic energy generated on a large scale and connected to the grid will produce everlasting power. This paper offers a detailed review of the grid-connected photovoltaic (GCPV) system and the different management and techniques related to it. Various aspects of the GCPV system have been explained throughout the paper which covers many different algorithms and software such as MATLAB, PVsyst6.7, etc. dedicated to researching many possible merits and demerits of the system. As the ever-increasing need for alternatives, this paper would provide a better understanding and knowledge of the GCPV system as a whole.

“…This study has different approaches for the analysis of the stability. In [16], [17] it was analyzed directly in the Nonlinear equivalent; however, this approach is not suitable for large systems. The passivity theory is used in [18] in order to study the small-signal stability of the VSC.…”

This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary grid without considering the control over specific variables (e.g., voltage and frequency), thus maximizing the amount of injected active power. The present study adopted the classical vector-oriented control based on the linearization method of the averaged model; hence, this analysis is limited to linear controls. The main objective of this study is to evaluate how each controller parameter influences the system’s stability. To conduct the sensitivity analysis, an averaged model in the dq reference frame of the VSC was employed to describe the system dynamics in the equivalent state-space model. Afterward, the stability was analyzed through a sensitivity analysis of the eigenvalues of the corresponding state matrix. The numerical results demonstrate that the main problems for the stability of VSCs operating as grid-following converters are threefold: a high value of the filter inductance, a non-ideal impedance that appears depending on the connection point, and poor coordination of the parameters of the Kp controllers. These results are compared to a simple bifurcation analysis of the state matrix, which consists of a diagram that describes the variation in eigenvalues when a parameter changes, thus proving their validity.
