Summary: This article discusses methods for enhancing the accuracy of micro phasor measurement units (mu PMUs) sampling instants in distribution grids. The start of each second of all mu PMUs is synchronized by the puke per second (PPS) signal of the global positioning system (GPS). The internal clock of each mu PMUs then determines the sampling instants till the next PPS. Accumulation of error due to clock inaccuracy and drift leads to excessive phase error. A lightweight algorithm is proposed to correct the sampling period by fine-tuning the timer count. Experimental results show that the maximum phase error is lower than the accepted phase error by about two orders of magnitude.

Summary: With increasing energy demand worldwide and the availability globally being lesser than the demands, Sub-Saharan Africa's richness in solar radiant has been looked into as a means of electricity generation. By covering just 1% of its land area with solar panels, countries in the region can generate over 2000 TWh of electricity daily. This necessitates reducing dependence on fossil fuel and upgrading existing grid systems into a Smart Grid to integrate renewable energy sources.

Summary: The increase in population and adoption of new power appliances has led to a significant rise in electrical demands, causing challenges for utilities in maintaining supply-demand balance and resulting in issues like load-shedding and power quality drops, particularly in developing countries. By implementing efficient demand-side management algorithms in metering instruments, it is possible to mitigate these issues and increase consumer awareness of energy consumption. Introducing IoT-based smart meters can provide solutions for monitoring, bidirectional data transmission, and load-clipping, helping to maintain power quality parameters within standard limits and improve the balance between supply and demand.

Summary: In the energy sector, IoT plays a role in improving the stability, efficiency, and utilization of power grids. This is achieved through advanced communication networks between smart meters and utility servers, allowing for secure and efficient power distribution. The proposed protocol ensures secure communication by delegating complex cryptographic operations to servers and managing the workload on smart meter nodes using lightweight primitives, such as Physically Unclonable Functions. The security of the protocol is proven using well-established cryptographic assumptions. Additionally, a countermeasure is proposed to protect against a physics-based attack called load modification attack.
