Timely and accurate data with high resolutions holds great promise for more responsible and advanced power grid operations. The research has been focusing on design of monitoring and control scheme given assumptions that the supporting Information and Communication Technology (ICT) systems are capable to provide data and perform control with sufficient quality. A relatively less addressed aspect is the dependency of Wide area monitoring and control (WAMC) systems on their supporting ICT architecture which is usually a compromise between various concerns, such as data quality, interoperability or security. Without an appropriate ICT architecture design, the projected WAMC system functionalities run the risk of being jeopardized. This paper begins with a presentation about possible delays brought by complex data transfer and processing processes. Analytical experiments are conducted with purposes to quantify the maximum delay and input signal's sensitivity towards delay on a typical WAMC application where the control of Static Var Compensation (SVC) is coordinated with generator excitations using phasor measurements. Given the characteristics of this particular control scheme, two possible ICT architectures that provide data with different qualities are compared concerning the reliability of this WAMC application. The paper is concluded by proposing a generic ICT architectures enabling efficient WAMC systems implementation in terms of data quality.
