Abstract
With the increasingly serious energy crisis and environmental pollution, the development and utilization of renewable energy resources have become an indispensable choice to ensure secure and sustainable energy supply. In recent years, the installed capacities of renewable generations such as wind power and photovoltaic are rapidly increasing, changing power generating sources of power systems from predominantly fossil power generation to high penetration of renewable generations. Unfortunately, the inherent uncertainty and variability of renewable energy sources will pose huge operational challenges in today’s power systems. At the same time, new emerging techniques, such as smart inverters, advanced communication protocols, and machine learning, provide more regulatory means available for better integration of high-penetration renewables. This paper deals with a mini-review of several emerging technologies for high-penetration renewable integration (HPRI). The main aim of this paper is the introduction of the basic concepts, principles, as well as the presentation of the main applications of these technologies in smart grids. Additionally, the challenges faced and future prospects of these technologies are also discussed. In this paper, an attempt has been made to present a comprehensive review of the research on emerging technologies in the field of renewable integration in recent years.
Highlights
With increasing concerns on energy crisis and environmental pollution, clean and low-carbon energy transition has become a broad consensus around the world (Flore et al, 2019)
Interoperability is an important basis for participating in the formulation of international standards, such as IEC 61850 and IEEE P2030, which stipulates technical terms, evaluation criteria and applications of engineering principles for smart grid interoperability in the energy and information technology, and some network standards like transmission control protocol
Speaking, future smart inverters are developing toward higher efficiency and smaller size; the application ranges of interoperability and communication protocols are supposed to be expanded; regarding machine learning (ML), deep integration of ML methods to make them more effective, intelligent, and interprein the application of high-penetration renewable integration (HPRI) should be further studied
