What is a voltage control strategy involving distributed energy storage?
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.
How do low-voltage distribution networks control voltage?
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.
What are the challenges faced by low-voltage distribution networks (lvdns)?
The increasing proportion of distributed photovoltaics (DPVs) and electric vehicle charging stations in low-voltage distribution networks (LVDNs) has resulted in challenges such as distribution transformer overloads and voltage violations.
How lvdn voltage is adjusted in a distributed energy storage system?
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.
Why does a low-voltage distribution network have a high proportion of PV?
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.
Can a voltage control strategy reduce voltage deviation of distribution network nodes?
Through case analysis, it is verified that the proposed voltage control strategy can reduce the voltage deviation of the distribution network nodes, effectively solve the problem of the distribution network voltage deviation, and reduce the active power loss. 1. Introduction
