Can a voltage control strategy improve low voltage distribution grid performance?

This study presents a novel voltage control strategy for low voltage (LV) distribution grids, addressing the lack of coordination between photovoltaic (PV) reactive control and energy storage system (ESS) active control. The proposed strategy concentrates on group coordination of PV and ESS to improve LV grid performance.

Can LV grid simulation improve voltage control performance?

Validated strategy with IEEE 14-node LV grid simulation, improving voltage control performance. This study presents a novel voltage control strategy for low voltage (LV) distribution grids, addressing the lack of coordination between photovoltaic (PV) reactive control and energy storage system (ESS) active control.

How to control voltage deviations in a PV system?

Hence, in instances of voltage deviations, the suggested approach is to prioritize the utilization of PV reactive power for voltage regulation, followed by tapping into the active power reserves of the ESS for further voltage control measures. 2.2.2. Voltage cost sensitivity factor for different nodes

How do ESS and PV control strategies reduce voltage violations?

As depicted in Fig. 7, the approach advocated in this study effectively eliminates the issue of voltage violations by coordinating the control of both PVs and ESSs. Compared with control strategy S2, control strategy S2 requires the ESSs to absorb 50.81 (kW·h) of power during simulation.

What is a control strategy for PV system voltage regulation?

Initially, a control strategy was suggested through a comparative analysis of the voltage cost sensitivity factor (VCSFs) associated with the PV system and the ESS. This strategy emphasized the prioritized use of reactive power from the PV for voltage regulation, followed by the utilization of active power from the ESS for the same purpose.
