| Summary: | Recent years, increasing trends on electrical supply demand, make us to search for
the new alternative in supplying the electrical power. A study in micro grid system
with embedded Distribution Generations (DGs) to the system is rapidly increasing.
Micro grid system basically is design either operate in islanding mode or
interconnect with the main grid system. In any condition, the system must have
reliable power supply and operating at low transmission power loss. During the
emergency state such as outages of power due to electrical or mechanical faults in
the system, it is important for the system to shed any load in order to maintain the
system stability and security. In order to reduce the transmission loss, it is very
important to calculate best size of the DGs as well as to find the best positions in
locating the DG itself.. Analytical Hierarchy Process (AHP) has been applied to find
and calculate the load shedding priorities based on decision alternatives which have
been made. The main objective of this project is to optimize the load shedding in the
micro grid system with unlimited DG’s by applied optimization technique
Gravitational Search Algorithm (GSA). The technique is used to optimize the
placement and sizing of DGs, as well as to optimal the load shedding. Several load
shedding schemes have been proposed and studied in this project such as load
shedding with fixed priority index, without priority index and with dynamic priority
index. The proposed technique was tested on the IEEE 69 Test Bus Distribution
system. |
