“…Nowadays, with the development of prediction, operation and control technologies, the penetration level of RES, such as photovoltaic and wind power, is gradually increasing, which means many synchronous generators are being replaced by power electronic devices. Due to the randomness and intermittency of the output power of RES generation, as well as the difference in grid-connected characteristics between power electronic devices and synchronous generators, large-scale RES generation will reduce the equivalent inertia and damping of the power system, and have negative impacts on the power system stability [3][4][5][6][7]. Therefore, it is of great theoretical and practical value to analyze the influence of RES generation on the damping characteristics of the system and propose the corresponding solutions.…”

Abstract:Aiming for large-scale renewable energy sources (RES) integrated to power systems with power electronic devices, the technology of virtual synchronous generator (VSG) has been developed and studied in recent years. It is necessary to analyze the damping characteristics of the power system with RES generation based on VSG and develop its corresponding damping controller to suppress the possible low frequency oscillation. Firstly, the mathematical model of VSG in a per unit (p.u) system is presented. Based on the single-machine infinite bus system integrated with an RES power plant, the influence of VSG on the damping characteristics of the power system is studied qualitatively by damping torque analysis. Furthermore, the small-signal model of the considered system is established and the damping ratio of the system is studied quantitatively by eigenvalue analysis, which concluded that adjusting the key control parameters has limited impacts on the damping ratio of the system. Consequently, referring to the configuration of traditional power system stabilizer (PSS), an auxiliary damping controller (ADC) for VSG is designed to suppress the low frequency oscillation of the power system. Finally, simulations were performed to verify the validity of theoretical analysis and the effectiveness of designed ADC.

Abstract-Photovoltaic Thermal (PV/T) combine the solar thermal and photovoltaic systems. This technique benefits from both light and heat of the solar radiation to produce electricity and hot fluids. Research in PV/T systems is rapidly growing with more methods and techniques to increase the overall efficiency, reduce the cost, improve the modeling, and maintain the system for long periods of time and employing them for suitable application. The paper aims to study some of the research conducted in this field in order to understand and derive key points to producing more research and providing constructive criticism for the work presented. Also a detailed explanation of PV/T systems' principles and operation is presented. Classifications of PV/T in terms of absorber design, shape of pipes, PV configuration, type of working fluid (base-fluid) and type of PV panels are all discussed in the literature survey. Finally, it is concluded that there is a clear lack in electrical, economic and environmental evaluations, where most of articles in PV/T are dominated by the thermal study of the system.
