Abstract:
An integrated power and energy loss optimization scheme consisting of Capacitor placement,
Network Reconfiguration(NR) and Distributed Generation(DG) placement for
the power and (lynanhic energy loss reduction and voltage profile improvement in pri-
- mary radial distribution systems is proposed here. Individual power and energy loss
reduction scheme i.e. Capacitor placement, NR and DG placement and combinations of
these are tested on IEEE-33 and IEEE-69 bus systems and are analyzed comparatively.
The different patterns of load types are taken into consideration to perform a practical
study. The variable output of DG is considered by connecting the solar PV units into
the distribution systems. Capacitors or the reactive power sources are considered if the
DG units are unable to inject the reactive power. The developed backward/forward
load flow method is used considering DGs as constant power sources. A meta heuristic
Harmony Search Algorithm (HSA) is used for simultaneously determining the optimal
reconfiguration and capacitor and DG sizes and locations. Different scenarios of Capacitor
and DC placement and reconfiguration are considered to study the performance of
the proposed method.
The objectives of this dissertation work are:
To propose an optimal dynamic power and energy loss optimization scheme.
Simulate the proposed scheme with IEEE-33 and IEEE-69 bus radial distribution
systems.
