Coordinated voltage and power flow control in distribution network

The UK government is pushing for continuous increases in Low Carbon Technologies (LCTs) which consists of electrical loads and microgeneration in the UK low voltage (LV) distribution networks. This is likely to pose significant changes on the voltage and power flow in the LV networks and consequent challenges to network devices and infrastructure. To solve the voltage and power flow problem without upgrading entire distribution networks, a coordinated voltage and power flow control method is proposed in the paper. This proposed method is evaluated by simulation and Network-in-Loop (NIL) emulation in the Smart Grid Laboratory at Durham University and shows benefits over conventional methods.
