“…Energy is forwarded to local segments toward granted users by a power switch. A power switch has been considered but for direct current (DC) [25]. However, handling of alternating current (AC) and energy storage interfaces as a feasible deployment are of interest.…”

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.

“…A basic transmission grid represents a current bulk power supply system from the power plant to mainly the pole transformer. A conventional wide-area synchronized grid is subdivided into small or medium sized cells, and connected through asynchronous and coordinated control power exchanges and the subdivided grid is called digital grid cell as in [1]. Some of the consumers inside the cell have PV generators.…”

“…We consider a smart grid to be integral to the realization of such a system. A digital grid [1] and informatization of energy [2,3] have also been proposed as components of such a system. Common specifications of smarttaps [4], on-demand power supply [5], power coloring [6], power packetization, and routing technology [7][8][9] have been examined practically.…”

Abstract-The present paper describes the feasibility of the FDM system using Mach-Zehnder filters for a power control system in a smart grid. The interconnection of large quantities of the distributed power sources, such as PV power sources, to the current bulk power grids is anticipated, and as a result, fluctuations of voltage and frequency will increase and make the adjustment of the power demand-supply balance difficult. By applying information communication technology to a power supply system in order to control the digital grid routers, energy-savings, and a stable power supply, the widespread use of renewable energy is expected. The digital grid cell includes numerous consumers, such as houses, office buildings and factories, which may or may not have PV power sources. The proposed FDM system enables the processing of a great deal of information to be exchanged incoherently between consumers and power generators, because the FDM system has the capability of 2 N transmission channels and the transfer functions of which can be expressed as the basis of the plain representation of the transfer function of the Mach-Zehnder filter. Using the FDM system, it will be possible to control a power supply system in a smart grid in order to maintain a stable power supply, energy savings, and a suitable adjustment of the power demand-supply balance.

“…Close monitoring of the grid's performance may be achieved by deploying parallel (auxiliary) sensing networks [4]- [13]. Concerns about ensuring working paths, which are perpetually energized translate into additional management complexity [11], [14]. Therefore, the adoption of a controlled distribution of power, which is seamlessly coupled with grid monitoring, becomes an important part of grid management.…”

“…Approaches to verify customers identification with an address before the start of an energy transmission can be applied to determine the electricity path [11]. However, the one-to-one interconnection required by these approaches limits its scalability, in terms of the number of connected customers.…”

Abstract-The present electrical grid uses two properties for the distribution of electrical power: perpetually energized and with discretionary access to power amounts. These two properties, although functional and practical, expose the grid to overload and consumption forecasting uncertainty. In addition, the distribution of electricity may be difficult to manage; sudden demand surge or supply shortage may ultimately lead to failures.To overcome this, we adopt a recently proposed approach whereby electricity is delivered in discrete amounts, through what is named here as a controlled-delivery power grid. In this grid, the customer's addresses are embedded in the electrical signal, and smart loads are used to limit the supplied electrical power. These smart loads not only control the consumed amount of power but also provide reactive stability to the distribution loop. We discuss an architecture of the controlled-delivery power grid and analyze a management scheme for the distribution of power, where the capacity of the distribution loop is capped to the average of the requested power, adopting a round-robin schedule of power deliverance. We show that the efficiency of power distribution satisfies over 98% of the power requests in such scenarios of energy scarcity.
