| Resum: | The evolution of Protection and Control (P&C) systems has developed though analogue and digital generations, and is presently advancing towards the utilization of Virtualization of Protection, Automation and Control environments (VPAC). This article focuses on redefining the features of traditional and modern P&C systems, Centralized Protection Automation and Control (CPAC), and VPAC, focusing on the integration of Intelligent Electronic Devices (IEDs) with secure communication that is time-effective in the centralized distribution of power and prevention of network vulnerability. Though standards such as IEC 61850-9-2 LE have been adopted, the actualization of full interoperability between diverse IED manufacturers remains elusive. With the digitization of technologies, P&C systems are naturally transitioning to virtual environments, with timing precision, redundancy and security being imperative. Latency and resource management and allocation in VPAC systems are considerable global issues. This paper discusses the issues of maintaining low operational performance in virtual substation environments while satisfying the requirements for performance in real time. The impacts of large volumes of data and artificial intelligence on the management of the grid are studied, and AI-based analytics that predict system failures and automatically change load flows are shown, as they have the potential to increase the flexibility and stability of the grid. The use of big data enables electric power utilities to enhance their protection systems, anticipate disturbances and improve energy management methods. The paper presents a comparative analysis between traditional P&C and its virtualized counterparts, with strong emphasis placed on the flexibility and scaling of VPAC resources. |
