Power Grid Advantages And Disadvantages
ABSTRACT The generation and transmission capabilities of the power system cause stress due to the demand of energy increase. Distributed generation (DG), refers to the power generation at the point of consumption such as generating power o-site, rather than centrally, eliminates the cost, inefficient, interdependences, complexity associated with transmission and distribution. However, unplanned application of individual distributed generators might cause other technical problems to the society that used it. The islanded is to secure the operation of DG during the system disturbance. Islanded is not a forceful or robust system when it is compared to DG. The methodology uses simulation approach to study voltage stability index (VSI). A …show more content…
Micro gird also loads capable of operating in parallel with the main power grid. A microgrid generally operates while connected to the grid. It can break off and operate on its own using local energy generation in times of crisis like storms or power outages or other reason. Micro Grid islanding is the future of efficient. It also is fast restoration of power system. Distribution generation into the power system allows the high penetration. A microgrid can be powered by distributed generators, batteries, and / or renewable resources like solar panels. Depending on how it 's fueled and how its requirements are managed, a microgrid might run …show more content…
The main objective of this project is to study voltage stability in distribution system, in order to analyses the impact of distributed generation on islanded distribution system. The phases of the project are described in detailed. Flow charts of the project are displayed in figure 4 and figure 5. Gantt charts are displayed at Appendix A and B. Description of project phases There are five phases of development that use to complete the project:- Phase 1 Literature Reviews Phase 2 Model of Bus Test System Data Phase 3 Calculate Voltage Stability Index Phase 4 Simulation 3.2.1 Phase 1: Literature review on previous works in voltage stability in islanded system The impact of distributed generation on islanded system is important for this study. Therefore, studying the analyses and the impacts of DG penetration on voltage stability is significant to access to the problem formulation. 3.2.2 Phase 2: Model of Bus Test System Data The standard IEEE 14 bus test system is used as a model. Different types of DGs (wind and diesel) are installed in the islanded system. The simulation is run by using MATLAB and PSAT

624 Words | 3 PagesThis section discusses the results are obtained from Matlab/Simulink software. The simulation consequences are obtained in two scenarios with taking in account the variation of wind generation. The first scenario examines the test system with SSSC, set on Line 1 and between the buses 1 and 2, but without power oscillation damping (POD) role. This exam is conducted through applying three-phase fault at midpoint of Line 2. The fault is applied at 1.33 second and it takes 10 cycles to clear the fault by the two breakers at the end of Line 2.

574 Words | 3 PagesExperiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

179 Words | 1 PagesExisting basic unit is shown in fig.2.1. As shown in fig.2.1, the basic unit consist of three dc voltage sources and five unidirectional power switches. In this structure, power switches (S_2,S_4),(S_1,S_3, S_4, S_5), and (S_1,S_2,S_3, S_5) should not be simultaneously turned on in order to protect the dc voltage sources from the short circuit. Table 2.1 shows the existing basic unit power switches turn on and off states, where the basic unit is able to generate three different voltage levels at the output that is 0, V_1+V_3, and V_1+V_2+V_3. It is important to note that the basic unit is only able to generate positive levels at the output.

If any sub-system's control system is shuts so in that case that sub-system area will effected. In addition, no need to shut whole system. In addition, if the fault is big so in that case that area power supply will start through another sub-station via grid system. Figure: decentralized system architecture
Pros And Cons Of Nuclear Power Plants
160 Words | 1 PagesPower plants burn fuel to produce heat to generate energy; however, nuclear power plants use the heat given off fission to turn water into steam. Nuclear energy is without a doubt a great way to power our homes because, Nuclear power plants are safer than other energy alternatives. Nuclear plants are safer than other energy alternatives. Coal is responsible for five times more deaths than nuclear power plants, coal also causes over one thousands more serious causes of illness than nuclear. Nuclear plants produce steam while coal plants, heat water by burning coal that produces greenhouse emissions.
