Integration of alternative energy sources into digital micro‐grids

Abstract

We overview different alternative energy resources and comment on their benefits and challenges. We highlight some features of alternative and sustainable energy resources and discuss some challenges for their integration into the power grid. In view of global trend toward blending alternatives and conventional energy resources in electrical power grids, a more robust energy distribution approach is necessary. Here, we present an alternative to the power grid with great potential for integrating alternative energy sources and defining microgrids-the Controlled-Delivery Grid (CDG). We comment how this new digital approach enhances the distribution of energy may help to resolve those challenges. We also examine the role of energy storage elements (batteries, super-capacitors), and sustainable energy resources in this new approach to the power grid. We provide some numerical analysis on the performance of energy distribution of the CDG and some experimental results that highlight some of its features.

Supersonically Sprayed Zn2SnO4/SnO2/CNT Nanocomposites for High-Performance Supercapacitor Electrodes

“…Rapid economic development based on increased use of nonrenewable fossil fuels has driven climate change and led to many types of pollution that harm the environment. Major changes in patterns of energy production and utilization will be required to avoid catastrophic effects. − Alternative and inexpensive renewable and clean energy sources are needed to solve this environmental and energy crisis . Electrical energy storage devices such as lithium-ion batteries and supercapacitors are needed for the effective use of solar and wind energy, which are inherently intermittent sources.…”

Active carbon based supercapacitors with Au colloids: the case of placing the colloids in close proximity to the electrode interface

“…S-C are used in a wide-range of applications, such as consumer electronic products, memory back-up devices, hybrid electric vehicles, power supply system [12][13]. They were also proposed as buffers to highly fluctuating power grids that are equipped with sustainable sources [14]. Our intent is to gain basic knowledge on the capacitance changes when incorporating very low dispersion of gold colloids with active-carbon (A-C) electrodes; these are deposited on a current-collector, made of grafoil.…”

Optically Controlled Supercapacitors: Functional Active Carbon Electrodes with Semiconductor Particles

“…They have found many energy applications due to their fast charging and discharging capabilities. Applications have also been proposed for the future digital micro-grid [ 10 , 11 ] and optical modulators [ 12 ]. Though much effort has been invested in the material, chemistry and electrical properties of batteries [ 13 ], and of S-C [ 14 , 15 , 16 ], surprisingly little research has been devoted to optoelectronic effects in S-C [ 17 ].…”
