IIi.features Of A Smart Grid

Our society today is ever more dependent upon electricity in all aspects of life. Keeping the power infrastructure throughout the United States secure and functioning properly should be considered a high priority for both private sector and government. Lacking properly functioning power caused by an outage has widespread impact not just on common conveniences being unavailable but also on critical areas such as emergency services, transportation, water distribution, communication and food production and storage.

The DOE was established to organize disjointed regulatory processes and create a national energy plan (Kuder et al., 2010). One of the main functions of the DOE is to monitor and report on the security of the smart grid. The primary objective of the reports are to provide data that may be

The Distributed is electrical power generation in small scale (usually 1MW to 50MW) near the load centre using either conventional techniques such as Diesel generators and micro turbines or using non-conventional techniques such as Photo-Voltaic, wind turbines and small hydro power. This modern concept of power system is very advantageous as it reduces the load on the grid, consumers get a reliable power of better quality, and consumers can supply surplus power to the grid and earn a considerable profit. Thus, adopting this modern concept of power system is not only beneficial for consumers but also to the utilities.

For the purpose of this discussion, the specifics of the electrical energy system in the United States are not important, rather an introduction to the basic elements of the system, who they serve, how they relate the larger whole and how they are regulated will suffice. On a most basic level the electrical grid, or system, in the United States is comprised of three basic components; the generation of electrical energy, transmission of this energy, and the distribution of this energy to end consumers.

The United States has an extremely well developed and maintained power grid which in its current state is configured primarily for non-renewable power generation. As the cost of green power comes down there will be an increasing amount of green power generation on the grid. This new, cleaner source of energy unfortunately has disadvantages that more traditional methods of power generation don’t suffer from, namely consistently. Photo-voltaic cells will only work when the sun is shining and wind turbines only spin when wind is present. I will be examining the readiness for renewable power of the power grid within the United States as well as investigating improvements that would allow for a larger national power generation percentage of renewable

With grid-tied renewable energy systems, there is no absolute need to conserve electricity or change your lifestyle. Your system will offset some or all of your usage, and your daily life can continue unchanged.

The core of this framework has five basic functions as it relates to cybersecurity: identify, protect, detect, respond, and recover (Framework for Improving Critical Infrastructure Cybersecurity). With regard to required compliance versus voluntary security, compliance with regulations does not ensure security. The BES consists of both generation and transmission assets and devices, but does not include system distribution. There are also potential risks associated with the technologies and operations of the distribution system though, so the distribution system must be included in the cybersecurity discussion. One such distribution security risk involves the increasing popularity of smart meters and the fact that there are no cybersecurity regulations associated with them. Of all the BES components, cyberattacks on transmission assets and devices pose the greatest risk to public safety due to a greater potential impact than attacks on other types of BES components. For example, the knockout of a transmission substation that is only the connection between multiple power lines, would have a higher

Everyone dreads going to the mailbox when you know your utilities bill will be in there any day. But what if I told you that their is new technology out there that will actually save you hundreds of dollars every year. Down below are just a few of many gadgets and tips. They range from home auditor's looking at your house to new thermostats. They will not only make bill time less stressful but turn a house into a home.

The DVR is one of the most common and effective solutions for protecting critical load against voltage sags [10] [11]. The DVR is a power electronic device used to inject three-phase voltages in series and in synchronism with the distribution feeder voltages in order to compensate for voltage sags. Moreover, it can be efficiently used to augment the fault ride through capability in wind applications. Detection time is an important factor in the voltage restitution process. Fast detection

Most people who live on the grid will see great benefits from a small system, sometimes even one that takes care of 20% of their bill.

Recently interest in Distributed Energy Systems (DES) is increasing, particularly onsite generation. This interest is because larger power plants are economically unfeasible in many regions due to increasing system and fuel costs, and more strict environmental regulations. In addition, recent technological advances in small generators, Power Electronics, and energy storage devices have provided a new opportunity for distributed energy resources at the distribution level, and especially, the incentive laws to utilize renewable energies has also encouraged a more decentralized approach to power

According to the case study written by Jurek, Bras, Guldberg, D’Arcy, Oh, and Biller, energy costs were steadily rising and were predicted to continue this trend going into the future. At the same time, utility companies were beginning to implement Smart Grid technologies to increase the efficiency of energy distribution. One resulting program to emerge from

One of the benefits of investing in this $100 million project includes rerouting power around bottlenecked lines. This allows Xcel Energy to deliver electricity to areas in Boulder that have a very high demand that the previous conventional electrical grid was unable to service effectively. This smart-grid system also enables Xcel Energy to detect and reduce power outages, identify false alarms more quickly and read customer meters remotely. This in return will lead to a reduction in the number of times the service crews are sent out to those locations, thus making the service crews more productive.

SmartNode SN4110 Series just like any typical electronic is made of the main circuit board with several different digital signal processor chips that allow the unit to maintain its functionality and it also runs a Linux based kernel as its operating system that allows human interaction capability via Graphic User Interface (GUI) on web browser or use command line interface such as Putty software terminal.

To the best of our knowledge, the variability and uncertainty impacts of excessive renewable energy generation on the unit commitment decisions and real-time dispatch of a micro grid with controllable DGs in the presence of ESS, demand response (DR) and interruption loads have not been investigated before. Thus, this paper examines probabilistic coordination of DERs on micro grid operation considering the associated uncertainties and hourly interruptible loads for a variety of customers. The work presented in this paper can be summarized as follows:
