In the low-voltage distribution network with a high proportion of PV, the voltage of the distribution network nodes increases, and some nodes exceed the limit during the photovoltaic output period, because the PV output is not synchronized with the load demand.
A voltage control strategy, involving distributed energy storage, is proposed in order to solve the voltage deviation problem caused by the high proportion of PV connected to the low voltage distribution network (LVDN). A voltage calculation method of the LVDN node with a high proportion of PV is proposed.
As explored by the authors of , according to the high R/X ratio of the low-voltage distribution network, the voltage is controlled by controlling the output power of photovoltaic power generation in the overvoltage period, but the active power of photovoltaic power generation output is reduced.
By controlling the injected power of the distributed energy storage, the LVDN voltage is adjusted, which is more conducive to dealing with the voltage exceeding the limit caused by the imbalance of the internal load in the partitions.
Real medium–low voltage test system This distribution system integrates the primary and secondary networks. The medium voltage network has 92 nodes, 2 substations, and 91 primary feeders. The low voltage network has 138 nodes, 32 DTs, and 106 secondary circuits.
The mathematical relationship among the node off-limit voltage, node off-limit power and energy storage exchange power is derived, and the voltage deviation of the distribution network can be suppressed by adjusting the injected power of the distributed energy storage.
