Distributed solar photovoltaic panels (PV) installed on the roofs of domestic houses generate electricity from sunlight, which is important for both decarbonization and electricity bill reduction. This paper proposes a new control approach to enable high density solar PV generation to be connected to low voltage (LV) networks more efficiently by working closely with in-home battery. The charging and discharging periods are crucially important for improving the efficiency of the PV battery. An optimal control scheme for energy storage systems in LV networks is introduced to facilitate demand response (DR). The method described also regulates thermal violation and voltage violation caused by PV generation. Finally, the paper uses a five node LV network and typical household profiles to demonstrate the effectiveness of the proposed control strategy. The benefits in terms of load shift are shown under three different configurations by using a selected lithium-ion battery.
