Abstract-More than 1.3 billion people in the world lack access to electricity and this energy poverty is a major barrier to human development. This paper describes a new concept of peer-to-peer electricity sharing which creates a marketplace for electricity. In this marketplace, the people who can afford power generating sources such as solar panels can sell electricity to people who are unable to afford generating sources or who might have access to electricity but require more electricity at certain times. These adhoc microgrids created by sharing of resources provide affordable electricity and are enabled by a Power Management Unit (PMU) described in this paper.

“…This improvement might result to the new standardization in home and commercial electrification, which can even revolute the manufacturing specifications of most daily used appliances. Garbesi [13,14] investigated the potential energy efficiency gain if household appliances are used in DC systems. Their study aimed to gain insight on the impact of modifying the appliances used in households and industries.…”

Electrical power systems are undergoing highly significant changes in their structures. The emergence of renewable energy units in the power generation sector, the use of high-voltage DC in the power transmission sector, and the prevalence of islanded or integrated microgrids in the distribution sector are the strongest evidence supporting this claim. These changes are mostly the consequences of the increasing energy demand rate, climate change, and environmental challenges, as well as the high investment and maintenance cost of the previous structures. Considering these new conditions and according to the recent development in DC/DC conversion topologies and control techniques, different studies have been conducted on how and why DC microgrids outperform AC microgrids. This study discusses the feasibility of the DC microgrid system according to recent developments in power systems. The efficiency and power loss reduction in DC distribution systems are then analyzed, some of the common strategies and devices for protection systems in such networks are reviewed, and the possible and existing challenges in developing the DC microgrids are highlighted. The mathematical calculations and theories for this evaluation are presented to determine the reliable justification for selecting the appropriate microgrid systems.

“…Important factors that favor the use of DC is the growing number of electric appliances that operate internally on DC and the fact that these new 'DC-internal' technologies tend to be more efficient than their AC counterparts [6]. 'DC-internal' appliances include communication technologies and all consumer electronics, such as computers, telephones, televisions, compact fluorescent lighting with electronic ballasts, light-emitting diodes (LEDs), and efficient DC motors [7].…”

“…Fluorescent and LED lighting uses one-quarter of the power, or less, than the traditional incandescent lighting it is replacing in the residential and commercial sectors. Brushless DC permanent magnet motors can save 5-15% of the energy used by traditional AC induction motors, and up to 30-50% in variable-speed applications for pumping, ventilation, refrigeration, and space cooling [6]. DC-motor-driven heat pump technologies for water and space heating can also displace conventional resistance heating with a savings of 50% or more.…”

“…Resistance heating applications like electric space heaters and water heaters can use either AC or DC as input power. All other major applications use motors, compressors, pumps, or fans, all of which proved to be most efficient in their DC-internal form [6]. Therefore, with energy efficiency guiding the selection of the hypothetical suite of appliances for both houses, it was decided to:…”
