“…Future systems require redesigning to accommodate uncertainties in power flows and in injections, as well as more distributed energy resources (DERs) [10]. Uncertainties will further increase as the inverter-based resources (IBRs) add novel dynamics to grid operation, lowering the inertia available to balance autonomously grid stability with novel control complexities [11]. Unfortunately, the past design paradigms to build stronger grids to ensure the security of supply while transporting more electricity are not suitable anymore [12].…”

Today's power systems are seeing a paradigm shift under the energy transition, sparkled by the electrification of demand, digitalisation of systems, and an increasing share of decarbonated power generation. Most of these changes have a direct impact on their control centers, forcing them to handle weather-based energy resources, new interconnections with neighbouring transmission networks, more markets, active distribution networks, micro-grids, and greater amounts of available data. Unfortunately, these changes have translated during the past decade to small, incremental changes, mostly centered on hardware, software, and human factors. We assert that more transformative changes are needed, especially regarding humancentered design approaches, to enable control room operators to manage the future power system. This paper discusses the evolution of operators towards continuous operation planners, monitoring complex time horizons thanks to adequate real-time automation. Reviewing upcoming challenges as well as emerging technologies for power systems, we present our vision of a new evolutionary architecture for control centers, both at backend and frontend levels. We propose a unified hypervision scheme based on structured decision-making concepts, providing operators with proactive, collaborative, and effective decision support.

“…Therefore, there are some serious concerns about frequency stability and control related to fully or mainly IBR-based larger power systems [26]. For example, [27] presents a system operator research agenda for future power systems and one of the six main research themes is related to inverter design.…”

Universal Grid-Forming Method for Future Power Systems

Power system inertia typically refers to the energy stored in large rotating synchronous generators. Dynamics and stability of the traditional power system is closely linked to the natural inertia of these synchronous generators. In recent years, increasing amount of synchronous generators have been replaced by high amount of different type of inverter-based generating units connected at different voltage levels of the power system. Therefore, the dynamics and stability of future low-inertia power systems will be increasingly dominated by the control and synchronization of these inverter-based resources. One essential issue is that the typical grid-following control with phase-locked-loop (PLL) -based synchronization of inverter-based generation is not enough to guarantee frequency stability in future low-inertia power systems. Therefore, different grid-forming inverter control and synchronization methods have been proposed and developed. Currently there does not exist any universal grid-forming control and synchronization method. Therefore, this paper tries to propose a new universal frequency-locked-loop (U-FLL) -based synchronization method which is grid-forming for inverter-based generating units and grid-supporting for inverter-based loads. Advantageous operation of the new U-FLL synchronization and control strategy is confirmed by multiple simulations with different shares of inverter-based resources and synchronous generators in MV and HV hybrid power systems as well as with 100 % inverter-based LV, MV and HV networks.

“…In turn, this means a lot has to be studied to obtain the power systems ready for the transition as such changes can compromise the main objective of the energy service. For instance, as more inverters are introduced into the system, some services, such as inertia response or high-fault current, can be compromised and may affect the stability of the system [3,16]. Furthermore, the variability of renewable energy resources or the behaviour of smart consumers drastically changes the traditional planning and operational paradigms.…”

In order to succeed in the energy transition, the power system must become more flexible in order to enable the economical hosting of more intermittent distributed energy resources (DER) and smart grid technologies. New technical solutions, generally based on the connection of various components coupled to the power system via smart power electronic converters or through ICT, can help to take up these challenges. Such innovations (e.g., decarbonization technologies and smart grids) may reduce the costs of future power systems and the environmental footprint. In this regard, the techno-economic assessment of smart grid technologies is a matter of interest, especially in the urge to develop more credible options for deep decarbonization pathways over the long term. This work presents a literature survey of existing simulation tools to assess the techno-economic benefits of smart grid technologies in integrated T&D systems. We include the state-of-the-art tools and categorize them in their multiple aspects, cover smart grid technology, approach methods, and research topics, and include (or complete) the analysis with other dimensions (smart-grid related) of key interest for future power systems analysis such as environmental considerations, techno-economic aspects (social welfare), spatial scope, time resolution (granularity), and temporal scope, among others. We surveyed more than 40 publications, and 36 approaches were identified for the analysis of integrated T&D systems. As a relatively new research area, there are various promising candidates to properly simulate integrated T&D systems. Nevertheless, there is not yet a consensus on a specific framework that should be adopted by researchers in academia and industry. Moreover, as the power system is evolving rapidly towards a smart grid system, novel technologies and flexibility solutions are still under study to be integrated on a large scale. This review aims to offer new criteria for researchers in terms of smart-grid related dimensions and the state-of-the-art trending of simulation tools that holistically evaluate techno-economic aspects of the future power systems in an integrated T&D systems environment. As an imperative research matter for future energy systems, this article seeks to contribute to the discussion of which pathway the scientific community should focus on for a successful shift towards decarbonized energy systems.
