In test system-II, primarily a two area multi source power system is considered with three GENCOs and two DISCOs in each area is shown in Fig. 8. The control area 1 and control area 2 comprises of reheat thermal, hydro and gas power system with the inclusion of non-linearities such as boiler dynamics, time delay (TD), governor dead band (GDB) and generation rate constraint (GRC). Boiler dynamics configuration is incorporated in thermal plants to generate steam under pressure. Changes in the…

The bending Factor The approach proposed by VAN DE WIEL (2003) considers plants as flexible elements and, therefore, incorporates mechanical aspects in the analysis. In his work, VAN DE WIEL (2003) refers to the study carried out by RAHMEYER et al. (1999), in which mechanical and resistance properties of different plant species were tested. RAHMEYER et al. (1999) stablished a relationship between the force required to bend the plant to an angle of 45 degrees in terms of the plant’s modulus of…

A Detectives Life Have you ever woken up one morning and decided you wanted to become a detective? I am researching this career because it is something I might want to do later on in life. It has always interested me and it is a super exciting career. This paper will explore the job description, requirements, and salary expectation, including the career path for a detective position. First, the job description for a detective includes many aspects. To begin, the general duties include several…

METHODOLOGY To optimize the losses of given system which will simultaneously upgrade the voltage at every bus, following methodology is opted which also includes the calculation of required shunt compensation. There are two cases: Case 1: Base case The problem formed is a non linear constrained optimization problem. Interior point method is used to solve this problem. The interior-point approach to constrained minimization is to solve a sequence of approximate minimization problems. It reaches…

“As a young boy, I was taught in high school, hacking was cool.” - Kevin Mitnick Tell me what is the first thing that comes to your mind when you hear the term ‘hacking’? Brighten up your imagination a bit more and tell me how do you portray a ‘hacker’? Well, I am sure most of the will imagine a hacker as a geek, who is mysteriously attractive and is surrounded by many computers with codes running in them. One term that is used by the majority of the population to describe a hacker is ‘cool’.…

The real danger of blackouts and brownouts is the unexpected computer shutdown. Operating systems are complex and they must go through a “Shutdown Sequence.” An unexpected loss of electricity can interrupt important threads, and leave your computer in an inoperable state. The biggest certain are the computer files because you’ll have to reboot the whole computer after that, losing those files. When it comes to frequent outages and surges, you lose the physical lifespan of a hard drive. Including…

working on wireless power transmission at his tower near Pikes Peak in Colorado Springs, Colorado. According to an article he wrote for Collier's Weekly in 1901, Tesla was conducting an experimenting at the site when he began to notice periodic electrical changes: "It was some time afterward when…

Have you heard about Benjamin Franklin? He is the one that discovered electricity. He is one very important person. If it wasn't for him, we wouldn’t be warm in the winter and we wouldn’t be cooled in the summer. He also invented the lightning bolt, bifocal eyeglasses, and the armonica. He also invented the franklin stove to keep houses warm. Benjamin Franklin was born January 17, 1706 in Boston Massachusetts. His father (Josiah Franklin) had 17 kids. Josiah Franklin had two wives, Abiah Folger…

What would you do if you were one of the smartest humans on earth in the 19th century? Could you invent things that defined modern era as we know it? What if I told you about a man who was one of the smartest and did made a significant change in the world history. Shouldn’t you know about him? Well, I think you should. Nikola Tesla was a Serbian American inventor born in 1856 in a small village in Serbia during the Austrian regime. In 1884 Tesla emigrated into the United States to work for…

plugged in along it a curling iron and maybe one of two more electrical items plugged in? Did you know what to do? Have you ever dropped something into water while it was plugged into an outlet in your kitchen and it again popped the little button out? If so, then the GFCI was doing what it is supposed to do. A GFCI or ground fault circuit interrupt is there for your protection. It is the first line of defense when using an electrical appliance in a potentially hazardous location in your home.…
