“…Photodiodes integrated in CMOS have been utilized as energy-harvesting devices for autonomous sensor nodes, identification tags, and implantable medical devices [1]- [3]. However, the open-circuit voltage of a silicon-based photovoltaic device (PV) is around 0.5 V, which is not high enough to drive transistors, particularly those made using old CMOS processes, which require a driving voltage of 1.8 V or higher.…”

This letter reports a localized substrate removal (LSR) process for on-chip electrical isolation to promote the generation of high voltages by backsideilluminated complementary metal-oxide-semiconductor (CMOS) photovoltaic (PV) devices. The proposed four-cell-cascaded CMOS PV module provides an open-circuit voltage of 2.05 V, a short-circuit current of 2.6 mA, and a conversion efficiency of 11% under 40-mW input laser intensity. The proposed LSR approach can also be used for the stacking of additional on-chip PV cells to generate even more voltage without the need for additional processing steps and without compromising device performance. High-voltage CMOS PV modules could be used in voltage-driven microelectronic circuits (>1.8 V) or currentdriven light sources (>1 mA) for a variety of applications. Index Terms-Complementary metal-oxide-semiconductor (CMOS), backside-illuminated photovoltaic device, localized substrate removal, micro-electromechanical systems (MEMS) process.

“…The usage of heterogeneous sensors, different computation engines, and a communication mechanism is widely applied in those systems. The authors of [6,7] proposed a Micro-controller Unit (MCU)-based device for monitoring photovoltaic (PV) power generation systems, where three types of sensors-temperature, irradiance, and humidity-were utilized to characterize the PV panels. The authors of [8] presented an MCU-based system that employed current and temperature sensors for monitoring thermal activities in power electronic converters of wind turbines.…”

Partial discharge (PD) is a major indicator of various failures in power grid systems. PD exhibits a physical occurrence where a localized electrical discharge happens in insulation materials. This phenomenon causes damage to the insulating parts and, in various circumstances, leads to complete insulation breakdown. As a consequence, it can produce more costly outcomes such as abrupt outages or lost production. Therefore, PD detection plays a vital role in preventing insulation failure. In this work, we propose a system that utilizes heterogeneous sensors for the PD detection along with multi-sensor interface, real-time advanced denoise processing, flexible system operation, and Bluetooth-low-energy (BLE)-based ad hoc communication. Among the variety of heterogeneous sensors, several are developed by the application of nanomaterials and nanotechnology, thus outperforming the regular types. The proposed system successfully identifies the presence of PD from sensor signals using a microprocessor-based processing system and effectively performs an advanced denoising technique based on the wavelet transform through field-programmable-gate-array (FPGA)-based programmable logics. With the development of the system, we aim to achieve a solution with low cost, high flexibility and efficiency, and ease of deployment for the monitoring of power grid systems.

Monitoring the thermal behavior of distributed energy resources (DERs) network explores the dualism between thermal effects and electrical power flow. This paper proposes a design concept that monitors thermal conditions of DER grids, using ZigBee/GSM wireless sensor networks (WSNs) for real-time monitoring in rural and remote areas. The concept seeks to improve upon existing designs by integrating composite functions. The functions comprise temperature conditions monitoring, data acquisition, and wireless data transmission including data storage and abnormal conditions alert/notification for control solutions. Thus, the concept determines the thermal impact on the DERs integrated network. WSNs with temperature sensors LM35 are utilized to complement ZigBee and Global System for Mobile Communications (GSM) technologies as a communication assisted link. Temperatures are measured from solar Photovoltaic PV modules, wind turbine, distribution cables, protection control units, and energy storage facilities. The ATMEGA328P microcontroller is assigned for signal and control processing. The circuit performance is coordinated and displayed on an LCD screen for normal conditions, whereas abnormal scenarios communicate through an alert/notification by GSM Short Message Service (SMS) protocol. The development analysis was performed through algorithm and circuit simulations. Proteus software was used for circuit design. Both the algorithm and circuit analysis passed the assigned simulation stages.Processes 2019, 7, 383 2 of 29 and material characteristics increases the power demand and hence causes severe thermal problems to the network. It then results in a reduced power quality [1,2]. Thermal behavior monitoring is relevant in electrical distribution networks for the performance of current, voltage, real power, and reactive power. It also influences the operation of protection and control systems.The thermal conditions scenario demands the DERs grid to have prompt system monitoring and potential self-healing schemes to address the development of faults using WSNs [2]. Discussions in [3,4] consent to the monitoring and reliable strategies of distributed power grid adapting to online monitoring to enhance system performance and integrity. The consent reflects the criteria for analyzing DER grid operations, hence involving Information Technology (IT) and Operational Technology (OT). The technological advancement for merging IT and OT improves data acquisition for system performance of DERs as smart grid [4]. Moreover, in [4,5] system planning, operation, and protection control, OT promotes efficiency in DER networks. The above discussions support online thermal conditions monitoring and controlling of the grid operations to achieve optimum performance. It is also consistent with the assertions in [3] which advocate that the DERs grid improvement cannot adequately be achieved without real-time and online conditions monitoring of components performance. Furthermore, active integration of the DERs network requires an innovativ...
