Transient Stability Improvement Of Power

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.

Scientists have been in a researching marathon to find the newest energy source to expand the variety of energy options. The alternative energy is used to call all the energy sources that replace using of fossil fuel. This tradition al kind of energy has enormous impact on the environment and threat the existence of living species. Specifically, renewable energy is unique type of energy that can’t be exhausted and be constantly renewed. This includes water, sunlight, geothermal heat, tides, and biomass. Being outstanding, wind power is now a major source of renewable energy in the US. As of April 2011, more than 41 GW of wind capacity has been installed, all of which is on land (Dhanju, Firestone, and Kempton). A single 1 MW turbine on land can provide enough electricity to

The greatest problem for wind power production integration into the electrical grid is intermittency. The wind is variable on different timescales, as turbulent gusts change the hourly production, and climate/temperature fluctuate the daily and sometimes seasonal power contained by the wind. This instability needs regulation and different operational reserves, in order to maintain grid stability and avoid electricity spillage/shortage.

Distributed generation in straightforward term can be characterized as a small scale generation. It is an active power generating unit that is connected at distribution level.

Voltage instability problems play a great role in power systems planning and operation. Nowadays, power systems are being performed closer to their steadiness limits due to economic and environmental constraints. Preserving a fixed and secure operation of the power system is hence a very vital and challenging issue.

The penetration level of distributed generators is increased due to the restructuring in electric power system.

Permanent Magnet Generators for wind systems are an integral part of the overall system, converting the mechanical energy from the turbine into electrical energy. But since wind is an inconsistent source of power, the generator must be able to adapt itself to power fluctuations, such as excess or shortage of load. Furthermore, standalone wind systems are provided with batteries which must be kept charged under all conditions when the power is available. Thus, a controller is necessary for wind generator to adapt itself to these fluctuations.

Abstract - With increasing load demand and global warming, an environment-friendly type of energy solutions to preserve the earth for the future generations has become a prerequisite. Other than hydro power, many such energy sources like wind and solar energy is highly potential sources to meet our energy demands. Systems which uses two or more renewable energy sources is is better than the single source system in terms of cost, efficiency and reliability. Standalone Wind/solar hybrid generation system offers a reliable and better solution to distributed generation for remote areas and localities where power from grid is not available. Natural energy-based power generation systems are always equipped with storage batteries to give

Distributed generation in straightforward term can be characterized as a small scale generation. It is an active power generating unit that is connected at distribution level.

Abstract— The purpose of this paper is to analyse the impact of three different Flexible Alternating Current Transmission System (FACTS) devices on a power system and to analyse their capabilities with respect to various disturbances. FACTS devices discussed in this paper are Static Var Compensator (SVC), Thyristor Controlled Series Capacitor (TCSC) and Unified Power Flow Controller (UPFC). The impact on power-flow and Power Oscillation Damping due to these devices is analysed in detail. Simulations based on different choices of Power Oscillation Damping (POD) signal are simulated for small and large disturbance incurred on the system. Effect of Linear (residue method) and Non-linear (CLF) based POD signals on the system is shown in the paper. Impact of each device is considered separately followed by a comparative study between them. All simulations are done with the help of SIMPOW© and all figures are plotted in MATLAB©.

Renewable power systems, which are capable of harvesting energy from, for example, solar cells, fuel cells, wind, and thermoelectric generators, are found in many applications such as hybrid electric vehicles, satellites, traffic lights, and powering remote communication systems. Since the output power of renewable sources is stochastic and the sources lack energy storage capabilities, energy storage systems such as a battery or a super capacitor are required to improve the system dynamics and

With increased additions of renewable sources in our existing infrastructure, major challenges are arising, as their supply is generally unstable and unpredictable. Too often, integrated renewable sources are curtailed and the energy is wasted for the safety of our existing electrical grid [1-6]. A logical solution would be to include large-scale energy storage systems, which would reduce the curtailment and increase the utilization of these clean sources, such as wind turbines and photovoltaics. A large-scale energy storage system would allow the renewable sources to store excess power during periods of low demand, and provide the stored energy during periods of peak electricity demand. Therefore, allowing renewable sources to provide
