Power utility companies are required to supply
customers with power within specified voltage limits. Voltage
rise in networks with distributed generators therefore poses a
challenge. This paper presents a coordinated network
controller whose objective is to maintain an optimal voltage
profile across the power network. The operations of
distributed generators, on-load tap-changing transformers
and reactive power sources are controlled. The controller is
modelled as an optimisation problem which is solved using
Particle Swarm Optimisation. The IEEE 30-bus test network
is then used to verify the effectiveness of the controller. The
results obtained show that this controller can greatly improve
the voltage profile of a power network by varying the
parameters of existing generation and voltage control
equipment.
