The current U.S. electrical power grid is an out-of-date infrastructure, and the Smart Grid is an upgrade that will add many new functionalities to meet customers’ new power requirements. Updating a system as complex as the electrical power grid has the potential of introducing new security vulnerabilities into the system. This document presents a review of the work related to Smart Grid cyber ...

An optimization methodology for the combination of several green technologies is introduced in this paper. These are smart meters, smart appliances, solar power systems and time-of-use (TOU) pricing. These technologies are collectively and widely utilized in the recent smart grid, which is rolling out all over the world to facilitate greener power generation and distribution. Adaptive particle ...

The response time of the smart electrical vehicle (EV) charging infrastructure is the key index of the system performance. The traffic between the smart EV charging station and the control center dominates the response time of the smart charging stations. To accelerate the response of the smart EV charging station, there is a need for a technology that collects the information locally and relay...

Smart grid is a new developing concept in power system. This technology observes the state of power system and intelligently take decisions to quickly clear faults, restores power and monitor demand to preserve the stability and performance of the electric power network formerly done by engineers. This paper discusses the technologies of smart grid and presents a developed model to illustrate t...

As an integral part of the Smart Grid, smart transformers both work independently to constantly regulate voltage and maintain contact with the smart grid in order to allow remote administration if needed and to provide information and feedback about the power supply and the transformers themselves. Through a process known as voltage optimization, a smart transformer provides the exact amount of...

An UPQC (Unified Power Quality Conditioner) is anequipment composed by two active conditioners operating in a combined way. One of the active conditioners is connected in series with the electrical power system, allowing the compensation of problems in the system voltages. The other active conditioner is connected in parallel with the electrical system, and allows the compensation of current ha...

Smart grid enhances optimization in generation, distribution and consumption of the electricity by integrating information and communication technologies into the grid. Today, utilities are moving towards smart grid applications, most common one being deployment of smart meters in advanced metering infrastructure, and the first technical challenge they face is the huge volume of data generated ...

Under the background of smart grid’s real-time electricity prices theory, a real-time electricity prices and wireless communication smart meter was designed. The metering chip collects power consumption information. The real-time clock chip records current time. The communication between smart meter and system master station is achieved by the wireless communication module. The “freescale” micr...

Smart grid has been introduced to address power distribution system challenges. In conventional power distribution systems, when a power outage happens, the maintenance team tries to find the outage cause and mitigate it. After this, some information is documented in a dataset called the outage dataset. If the team can estimate the outage cause before searching for it, the restoration time will...
