With the rapid development of power system technology, the requirements for the stability of power equipment operation are higher and higher. In order to ensure the stability of power equipment operation, this paper puts forward the dynamic detection method of long-distance communication fault of power information acquisition terminal. Through the collection of remote communication fault dynamic information, data preprocessing. And the fault area is accurately located to determine the fault location. Through the power information acquisition terminal to determine the abnormal value, the detection effect of communication fault can be realized. According to the experimental comparison, it can be seen that compared with the traditional fault detection methods, the large interval dynamic detection method of power information acquisition terminal remote communication fault has higher detection accuracy and significant advantages.

“…Design, control, protection [16,17], security [18], operation status (grid-connected or/and island mode), and energy management [19] are the main areas of the MG field. The LAMBDA MG LAB consists of several sources: a 12 kW three phase PV system (PV1), a single-phase PV system (PV2) with 2 kW rated power, an emergency generator set (EGS) with 5.2 kW installed for island mode, a battery energy storage system (BESS) with 6.5 kWh of rated capacity (2.2 kW charge, 1.8 kW of AC discharge), and an uninterruptible power supply (UPS) to supply the electronic components [20].…”

Currently, despite the use of renewable energy sources (RESs), distribution networks are facing problems, such as complexity and low productivity. Emerging microgrids (MGs) with RESs based on supervisory control and data acquisition (SCADA) are an effective solution to control, manage, and finally deal with these challenges. The development and success of MGs is highly dependent on the use of power electronic interfaces. The use of these interfaces is directly related to the progress of SCADA systems and communication infrastructures. The use of SCADA systems for the control and operation of MGs and active distribution networks promotes productivity and efficiency. This paper presents a real MG case study called the LAMBDA MG testbed laboratory, which has been implemented in the electrical department of the Sapienza University of Rome with a centralized energy management system (CEMS). The real-time results of the SCADA system show that a CEMS can create proper energy balance in a LAMBDA MG testbed and, consequently, minimize the exchange power of the LAMBDA MG and main grid.

“…The control and measurement signals close the loop between the cyber and the physical layers, thus representing the key technologies for achieving a stable, reliable, and resilient CPS-based power system architecture [22,23]. In this framework, the development of different computing methodologies, e.g., adaptive real-time scheduling [24] or novel hierarchical control techniques for power systems (from micro-grids to power distribution and transmission systems) [25][26][27], are active areas of research in modern power systems in order to analyze the multiple layers of the CPS framework.…”

Towards the Integration of Modern Power Systems into a Cyber–Physical Framework

The cyber–physical system (CPS) architecture provides a novel framework for analyzing and expanding research and innovation results that are essential in managing, controlling and operating complex, large scale, industrial systems under a holistic insight. Power systems constitute such characteristically large industrial structures. The main challenge in deploying a power system as a CPS lies on how to combine and incorporate multi-disciplinary, core, and advanced technologies into the specific for this case, social, environmental, economic and engineering aspects. In order to substantially contribute towards this target, in this paper, a specific CPS scheme that clearly describes how a dedicated cyber layer is deployed to manage and interact with comprehensive multiple physical layers, like those found in a large-scale modern power system architecture, is proposed. In particular, the measurement, communication, computation, control mechanisms, and tools installed at different hierarchical frames that are required to consider and modulate the social/environmental necessities, as well as the electricity market management, the regulation of the electric grid, and the power injection/absorption of the controlled main devices and distributed energy resources, are all incorporated in a common CPS framework. Furthermore, a methodology for investigating and analyzing the dynamics of different levels of the CPS architecture (including physical devices, electricity and communication networks to market, and environmental and social mechanisms) is provided together with the necessary modelling tools and assumptions made in order to close the loop between the physical and the cyber layers. An example of a real-world industrial micro-grid that describes the main aspects of the proposed CPS-based design for modern electricity grids is also presented at the end of the paper to further explain and visualize the proposed framework.
