Abstract

Aiming at the status quo that the reactive control of photovoltaic （PV） inverters and active control of energy storage system （ESS） are not sufficiently coordinated in the low-voltage distribution network, a coordinated voltage control strategy for PV inverter and ESS group based on consensus algorithm is proposed. Firstly, according to the voltage-cost sensitivity F^U-F of different regulating devices, it is proposed to use the PV inverter reactive voltage regulation before using the energy storage active voltage regulation. Then, according to the F^U-F of different node regulating equipment, the regulating equipment is grouped, and it is proposed to prioritise the use of the group with larger F^U-F to participate in regulating. Then, in the PV inverter reactive regulating stage, reactive power utilisation is used as the consensus variable within the group, and in the ESS active control stage, the amount of state of charge （SOC） change is used as the consensus variable within the group, and the groups are coordinated through the coordinated control to jointly achieve the convergence of key node voltages to the set value. Finally, an example simulation is carried out using an IEEE 14 node low-voltage distribution network containing distributed PV and ESS to verify the effectiveness and correctness of the proposed group coordinated control strategy.
