“…On one end, the high cost of an EMS directly affects the grid transformer. Alternatively, the performance of the transmission and distribution transformers in the power system might be compromised by the use of less expensive materials 155 . Power transformer economic cost reduction requires a combination of strategic planning, effective operation, and wise investment selections.…”

This paper develops a technical framework for the next‐generation power grid transformer (NGPGT) for grid renewables. This framework is structured to overcome the environmental challenges produced by the explosive use of nonrenewable base energy generation sources. The use of these sources cannot meet the required electricity for the world's growing community due to their availability, cost, and lack of flexibility. However, modern energy systems focus on the use of renewable energy sources, where the grid transformer's interaction plays an essential role in their generation, transmission, and distribution. The lack of centralization, local monitoring, interoperability, authenticity, and precise bi‐directional flow may limit the application of current framework power grid transformers in grid renewables. In this paper, a new technical framework, called NGPGT, is developed by introducing some extended features for addressing the challenges shown in current‐generation transformers. This is structured by enabling some advanced technical features with the existing framework, which includes automatic condition monitoring, intelligent inverters, edge computing, automatic controlling, and intelligent management. This paper also illustrates the benefits and scope of the NGPGT compared to the existing transformer by assembling essential requirements and obligatory components. Additionally, this paper highlights a few difficulties of implementing NGPGT in terms of operational, communication, energy management, and economic points of view, which may enable further research scopes for the researchers.

This paper develops a technical framework for the next-generation power grid transformer (NGPGT) for grid renewables. This framework is structured to overcome the environmen-tal challenges produced due to the explosive use of non-renewable base energy generation sources. The use of these sources cannot meet the required electricity for the world’s growing community due to their availability, cost, and lack of flexibility. However, modern energy systems focus on the use of renewable energy sources where the grid transformer’s interaction acts the essential role in their generation, transmission, and distribution. The lack of central-ization, local monitoring, interoperability, authenticity, and precise bi-directional flow may limit the application of current framework power grid transformers in grid renewables. In this paper, a new technical framework, called NGPGT, is developed by introducing some ex-tended features for addressing the challenges shown in the current-generation transformers. This is structured by enabling some advanced technical features with the existing frame-work which includes automatic condition monitoring, intelligent inverters, edge computing, automatic controlling, and intelligent management. This paper also illustrates the benefits and scopes of the NGPGT compared to the existing transformer by assembling essential re-quirements and obligatory components. Additionally, this paper highlights a few difficulties of implementing NGPGT in terms of operational, communication, energy management, and economic point of view which may enable further research scopes for the researchers.

“…This will result in a two-way flow power grid, in which passive non-monitored consumers will pass to monitored & controlled "prosumers", with massive probabilistic energy injection at all system levels. That is why, behind the scene, smart grid [1], [2] concepts were developed in the past twelve years, to maximize IED & systems integrated intelligence, and that is nowadays simply mandatory [3], [4]. It seems to be a business revolution that highly ushers an improved utility intelligence at all levels, in a so much higher level, for sure more than nowadays monitoring, automation and control.…”

Recognizing that to survive in 21 th century, utilities must take advantages of smart platforms, IEC has provided a homogeneous IT landscape based on CIM/XLM standardized data format for source data. It allows utilities to vitally combine their large number of autonomous IT systems, with great potential for optimizing their core processes. But this landscape itself will not be enough, unless utility actually and smartly connects IEDs and systems at that surviving critical level. This article presents an approach that tries to make easier the utility improve core processes, based on substation "smartizing", by means of creating in smart substations, key-value operating and functional data, information and knowledge, in a continuous upstream add-value process, making them suited to each IED, System and decision maker at every utility level. "Smartizing" architecture is fully IEC compliant. The approach is being applied in a 25 MVA distribution substation in Brazil, in a 10 GW demand peak utility group.  
