Abstract:
|
The electric power distribution network has traditionally been operated in a passive mode
where most of the electricity was generated by large power plants, delivered to the customers
through distribution networks. Thus the flow of real and reactive power was from the higher
to the lower voltage levels. Recently, distributed generations (DG) with renewable energy are
expected to play an increasing role in emerging electric networks in response to the climate
change challenge and the need to enhance fuel diversity. With the introduction of the DG, the
power flows may become reversed since the distribution network is no longer a passive circuit
supplying loads but an active system with power flows and voltages determined by the
generation as well as load.
Due to the fact that distribution network has been designed to work in the passive form,
increasing power injections from DG units results in numbers of negative impacts. Voltage
control problem can be addressed as one of the major impacts of using DG units in power
system and the voltage rise effect is regarded as a key factor that limits the amount of
additional DG capacity that can be connected to the distribution networks.
The aim of this project is to study the different techniques of voltage control, which are
employed on the distribution networks including DG units.
The first part of this project consists of overview about the traditional structure of powers
system and its characteristics. After that, we study the impacts of using DG units in
distribution system. On the next part, different voltage control techniques will be presented
and their main advantages and disadvantages will be introduced. For a better understanding of
these techniques, different simulations will be done using NEPLAN software. |
