Distributed generation and low carbon loads are

already leading to some restrictions in the operation of distribution networks

and higher penetrations will exacerbate such problems. Therefore, increased

real-time monitoring and control becomes a necessity. In the future,

distribution network operators will have smart meter measurements available to

them to facilitate safe and cost-effective operation of distribution networks.

This research investigates the application of domestic smart meter measurements

to extend the observability of distribution networks. An integrated load and

state estimation algorithm was developed and tested using residential smart

metering measurements and an a hypothetical distribution network. Simulation

results show that smart meter measurements, both real-time and

pseudo-measurements derived from them, can be used in conjunction with state

estimation to extend the observability of a distribution network. The

integrated load and state estimation algorithm was shown to produce accurate

voltage magnitudes and phase angles at each busbar of the network. As a result,

the algorithm can be used to enhance distribution network monitoring and

control.
