Description: This a power generating method from sunlight.This method of power generation is simple and is taken from natural resource. This need only maximum sunlight to generate power. This project helps for power generation by setting the equipment to get maximum sunlight automatically. This system is tracking for maximum intensity of light. When there is decrease in intensity of light , this system automatically changes its direction to get maximum intensity of light.
Here we are using two sensors in two directions to sense the direction of maximum intensity of light. The difference between the outputs of the sensors is given to the microcontroller unit.

Description: 优秀论文配套源码。分布式电源的接入使得配电系统从放射状无源网络变为分布有中小型电源的有源网络。带来了使单向流动的电流方向具有了不确定性等等问题，使得配电系统的控制和管理变得更加复杂。但同时，分布式电源又具有提高电网可靠性，绿色节能，等等优点，所以为更好的利用分布式电源为人类造福，我们必须对其进行研究与分析。
本文采取通过利用仿真软件Matlab编写计算潮流程序模拟分布式电源接入配电网的模型进行潮流计算的方法对分布式电源的稳态影响进行探索与分析。
选取了34节点的配电网网络模型，通过对单个以及多个分布式电源的接入位置以及容量的不同情况对34节点配电网的网损以及节点电压状况进行了分析。
-The distributed generation access to distribution system makes passive radial distribution network to active medium-sized power distribution network. It brings uncertainty to one-way direction power flow, etc., and it makes the control and management of the distribution system more complicated. Otherwise, it can bring a lot of benefits, such as more reliable, and it is green power. The distributed generation should be better known , so we can benefits more.
So the program called Matlab was used to compile a program to solve the power flow problem. By this program, we can text which factor can influence the distributed generation’s access to the distribution system.
The IEEE 34 Node model was chosen to be discussed how different factors can influence the power quality. This article analyzes distributed generation’s influence to the distribution system of energy lost and voltage level.

Description: The paper gives an overview regarding power
electronics control of wind energy. The development of
modern power electronics has been briefly reviewed.
The applications of power electronics including control
in various kinds of wind turbine generation systems and
offshore wind farms are also illustrated, showing that
the wind turbine behavior/performance is significantly
improved by using power electronics. They are able to
act as a contributor to the frequency and voltage control
by means of active and reactive power control.
Finally, a status of the wind turbine market is given
and some future trends are highlighted. Wind energy
will be an important power sources in the future power
system.

Description: Abstract—In this paper a current reference generation
method for a voltage source shunt active power filter is
examined. The proposed method improves the harmonic
filtering by compensating the delays in the system. In
stationary operating point of the load the method uses
measurement data sampled in previous periods to generate a
reference prediction. Since in transient state of the load the
prediction no longer holds true, a computational control delay
compensation algorithm is used in the reference generation
instead of the prediction in this situation. Changing the
algorithm according to the operating point guarantees effective
harmonic compensation in all operating points. In this paper
the system performance is examined with an active filter
simulation model. Platform: |

Description: Frequency control as a major function of automatic generation control is one of the
important control problems in electric power system design and operation, and is
becoming more significant today because of the increasing size, changing structure,
emerging new uncertainties, environmental constraints and the complexity of power
systems.
In the last two decades, many studies have focused on damping control and voltage
stability and the related issues, but there has been much less work on the power
system frequency control analysis and synthesis. While some aspects of frequency
control have been illustrated along with individual chapters, many conferences and
technical papers, a comprehensive and sensible practical explanation of robust frequency
control in a book form is necessary Platform: |
