The modern electric power grid is a complex interconnected network of independent physical and electronic devices that utilize myriad technologies for communication between other devices and with centralized control centers. These technologies may be compromised by malicious parties which may, in turn, lead to degraded performance or a failure of the communications infrastructure, ultimately re...

Electric vehicles (EVs) are an emerging type of mobile intelligent power consumption devices in Smart Grid as new green transport tools. In order to provide a powerful automation and intelligence support for wide area electric vehicles energy service network, we analyze the network infrastructure and communications demands of various terminals, devices and monitoring systems distributed in wide...

For the third time in a generation, our nation is focusing attention on the thorny questions of national energy security. This time, however, it isn't just concern about fuel shortages and price spikes; it is also about the potential impacts of deliberate attacks on energy facilities, including the nations power plants and electric grids. Regulators and other public officials must now assess an...

This paper presents a mathematical model and a methodology to analyze the losses in transmission expansion planning (TEP) under uncertainty in demand. The methodology is based on discrete particle swarm optimization (DPSO). DPSO is a useful and powerful stochastic evolutionary algorithm to solve the large-scale, discrete and nonlinear optimization problems like TEP. The effectiveness of the pro...

A model for blackouts in electric power transmission systems is implemented and studied in simple networks with a regular structure. The model describes load demand and network improvements evolving on a slow timescale as well as the fast dynamics of cascading overloads and outages. The model dynamics are demonstrated on the simple power system networks. The dynamics depend weakly on the networ...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...
