A electric grid works as a power distribution system and carries electric powers through different power lines. Since grid cannot store any power anyplace within the system. We got several customers consuming megawatts of power at any moment. At that very same moment, we have got dozens of power plants manufacturing precisely the correct amount of power to satisfy all of that demand. And you've got all the transmission and distribution lines sending the power from the power plants to the customers
to store electricity Of all the storage technologies, the energy storage battery is the one with the widest range of applications. Batteries are used for electric vehicles, portable electronics, electric utility energy storage,

I am greatly inspired to accomplish my aspiration to become a professional in the field of Power and Energy Systems. Beside aspiration the other reason I am choosing electrical power is of job perspective that the jobs related to electrical power are almost in every industry from smaller to a multinational. In under-graduation program I learned THEORY
1.1 Introduction The benefits of introduce Electric Vehicle (EV) into power network have been demonstrated in vast amount of literatures. Functionalities such as damping out the oscillation of electricity quality, responding to demand schedule, acting as the back-up reserve and accommodating the penetration of wind power generation are sufficiently analysed based on the assumption of perfect prediction and management of EV mobility. However, there exist many drawbacks of oversimplified assumption
Electric Lineman The importance of an electrical lineman is huge, not only in the community but also in most of the world. Their education, training, and correct use of equipment help them in their different and dangerous work conditions to accomplish the tasks of providing power to their communities. To be a lineman one would first have to go through the apprenticeship program. The apprenticeship program involves approximately 7,000 hours of training over a four-year period and includes both classroom
universal in the operation and control of electric power transmission. It consists of making synchronized measurements of phasor quantities of voltages and currents at several points spaced hundreds or thousands of kilometers points. Phasor Measurement Unit (PMU) technology provides phasor information (both magnitude and phase angle) in real time. The importance of data provided by PMUs has been well recognized after a number of major blackouts in many power systems in different parts of the world

In this section, The basics of electromagnetic transients, HV Capacitors banks and their relations and functions in the power system are presented. Electromagnetic Transients (EMT) Electromagnetic transient (EMT) phenomena occurs in the power system when the network changes from one steady state into another which creates a disturbance in the power system that involve destructive high magnitudes of current and voltage or even both, as per (ANSI std. 1100-1992) the EMT is defined as “a sub-cycle
2.3 Power Flow Analysis 2.3.1 Introduction The power flow problem, or load flow problem, is the problem of determining the operating characteristics of a power system in steady-state [19, 36]. A power system usually has plenty of pathways, the power flow analysis technique is expected to compute the power flows over all the pathways and the voltage magnitude and angle at each bus with the help of a certain number of non-linear mathematical equations[10]. Besides the calculation of electrical
privatising the generation, transmission and distribution of electricity. According to Young (2001), the considerable number of privatisations can be explained by the intention of improving the efficiency and a more economic reason concerning the proceeds of the flotation. As far as the case of electricity is concerned, David Parker (1999) argues that the main reason was to promote competition and that all the producers of the four activities (generation, transmission, distribution and supply), could

When a short-circuit fault occurs on a transmission line, it should be located rapidly and correctly in order to repair the faulted section, minimize the transmission line outage time, and restore power delivery as soon as possible. Therefore, development of a robust and accurate fault location technique under various fault conditions is a highly important research area. In some low power densities areas, utilities are connected to an existing transmission line using a tapped line because of economic
