  The aim of distribution networks is to meet their local area power demand
with maximum reliability. As the electricity consumption tends to increase
every year, limited line thermal capacity can lead to network congestion.
Continuous development and upgradation of the distribution network is thus
required to meet the energy demand, which poses a significant increase in cost.
The objective of this research is to analyze distribution network topologies
and introduce a topology reconfiguration scheme based on the cost and demand of
electricity. Traditional electrical distribution networks are static and
inefficient. To make the network active, an optimal dynamic network topology
reconfiguration (DNTR) is proposed to control line switching and reconnect some
loads to different substations such that the cost of electricity can be
minimized. The proposed DNTR strategy was tested on a synthetic radial
distribution network with three substations each connecting to an IEEE 13-bus
system. Simulation results demonstrated significant cost saving in daily
operations of this distribution system.
