“…Recent works (see, for example, refs. [95][96][97]) also propose energy storage systems as influencers of grid electricity reliability and contribute to grid reliability enhancement. All electric power grid infrastructures depreciate over time and, therefore, face challenges as they age; for instance, [20,44,88,91] reported the aging of grid components as influencers of grid electricity reliability.…”

The reliability of the electricity supply is important since any interruption to the supply has direct and indirect consequences for its users. A reliable electricity supply requires a reliable electrical grid system to transmit and distribute the power from the generating plants to the consumers. This study reviewed the literature to find out how the reliability concept has been understood with a special focus on grid electricity reliability, what factors influence grid electricity reliability, what measures have been used to measure grid electricity reliability, which theories and methodologies have been applied to study grid electricity reliability and what are the likely research gaps that require future address. This review found that the literature documents four categories of factors that influence grid electricity reliability, and these are environmental, security, organizational and technical. The biggest influencers of grid electricity reliability were the technical-related factors followed by the environmental-related factors. In addition, we found that sixty studies focused on one subsystem, eleven on two subsystems while seven studies considered three subsystems. Most studies were found to address the distribution of subsystem reliability. As per the methodology adopted, this review found that eleven studies used a qualitative approach, forty-five studies used a quantitative approach, while eleven studies used a case study approach to study the concept of grid electricity reliability. In addition, we found that thirty-seven studies used the duration and frequency of power outages to measure grid electricity reliability.

“… 5 , 6 However, a deeper penetration of PV energy will only be implementable with scalable, affordable, and sustainable energy storage, owing to dramatic fluctuations in the PV power. 7 , 8 , 9 Therefore, tremendous efforts have been made to develop energy storage technologies, including electrochemical energy storage, phase change energy storage, flywheel energy storage, and compressed air energy storage. 10 , 11 , 12 However, the thermal storage capacity of building envelopes has largely been overlooked, despite the fact that the thermal energy loss of a building envelope is responsible for the majority of the total energy consumption and its thermal inertia has considerable thermal storage potential.…”

Gallium Nitride (GaN), as the representative of wide bandgap semiconductors, has great prospects in accomplishing rapid charge delivery under high‐temperature environments thanks to excellent structural stability and electron mobility. However, there is still a gap in wafer‐scale GaN single‐crystal integrated electrodes applied in the energy storage field. Herein, Si‐doped GaN nanochannel with gallium oxynitride (GaON) layer on a centimeter scale (denoted by GaN NC) is reported. The Si atoms modulate electronic redistribution to improve conductivity and drive nanochannel formation. Apart from that, the distinctive nanochannel configuration with a GaON layer provides adequate active sites and extraordinary structural stability. The GaN‐based supercapacitors are assembled and deliver outstanding charge storage capabilities at 140 °C. Surprisingly, 90% retention is maintained after 50 000 cycles. This study opens the pathway toward wafer‐scale GaN single‐crystal integrated electrodes with self‐powered characteristics that are compatible with various (opto)‐electronic devices.
