“…Consequentially, such CPESs can be regarded as organic computing systems [27,34] as they continuously and dynamically adapt to exogenous and endogenous changes on various time scales -from significant changes in generation technologies driven by external regulatory and political factors to unforeseen demand fluctuations due to stochastic human behaviour. To cope with these dynamics, the system is characterized by self-* properties, e.g., self-organization of battery storage swarms [41], self-configuration of SCADA and protection systems [43], self-explanation, and context awareness [5].…”

Digitalization enables the automation required to operate modern cyber-physical energy systems (CPESs), leading to a shift from hierarchical to organic systems. However, digitalization increases the number of factors affecting the state of a CPES (e.g., software bugs and cyber threats). In addition to established factors like functional correctness, others like security become relevant but are yet to be integrated into an operational viewpoint, i.e. a holistic perspective on the system state. Trust in organic computing is an approach to gain a holistic view of the state of systems. It consists of several facets (e.g., functional correctness, security, and reliability), which can be used to assess the state of CPES. Therefore, a trust assessment on all levels can contribute to a coherent state assessment. This paper focuses on the trust in ICT-enabled grid services in a CPES. These are essential for operating the CPES, and their performance relies on various data aspects like availability, timeliness, and correctness. This paper proposes to assess the trust in involved components and data to estimate data correctness, which is crucial for grid services. The assessment is presented considering two exemplary grid services, namely state estimation and coordinated voltage control. Furthermore, the interpretation of different trust facets is also discussed.CCS Concepts: • Hardware → Smart grid; • Security and privacy → Trust frameworks.

“…SPVSs and microgrids consist of power electronic interfaces (PEI) which make these systems highly controllable and flexible for modifications [13,14,15]. The reconfigurable power system is one of the proposed concepts to increase the controllability of the existing power system [16,17]. It is expected that the SPVS based reconfigurable systems will play a major role in future distribution networks.…”

Even though solar power generation has become an emerging trend in the world, its penetration into the utility grid as a distributed generation source is not a satisfactory measure due to the inherent issues related to solar photovoltaic systems (SPVSs). In addressing these issues, microgrids have been identified as suitable integrating platforms for distributed, clean energy resources such as SPV. Different SPV and microgrid architectures are available for different applications depending on the resource availability and controllability. Reconfigurability is a concept that makes a system adaptable to two or more different environments by effectively utilizing the available resources. The review explains the applications of reconfigurable approaches on solar PV systems such as reconfigurable PV arrays, power conditioning unit (DC/DC converter, DC/AC inverter), microgrid controller and topology of distribution network with relevant studies. An analysis is also presented considering the unique features of reconfigurable systems in comparison to the static systems.

The digitalization of substations leads to a high degree of automation, which is referred to as Digital Substations with the use of the IEC 61850. An increase in cybersecurity is necessary, and technically enabled by detection and incident response systems – security-by-design is currently often secondary. The next transformation step of substations is introduced and outlined in this paper as a cyber-resilient digital substation. Based on a state-of-the-art description, this paper presents a definition of cyber resilience for digital substations as a basis for the introduced cyber resilience monitor. The monitor acts as a central instance for recording, assessing and responding to security threats and incidents. Furthermore, the requirements for the system structure of the cyber-resilient digital substation are shown and underpinned with current research approaches.
