Voltage Control Strategy for Low-Voltage Distribution Network with Distributed Energy Storage Participating in Regulation under Low-Carbon Background

With the gradual advancement towards goal of carbon neutrality, photovoltaic power generation, as a relatively mature zero-carbon technology, will be connected to grid in an increasing proportion. A voltage control strategy, involving distributed energy storage, is proposed order solve deviation problem caused by high proportion PV low distribution network (LVDN). calculation method LVDN node with proposed. According nodes running throughout day, fuzzy cluster analysis was used partition LVDN. two-objective mathematical model for optimizing storage constructed, and particle swarm optimization algorithm model. strategy based on sensitivity proposed, established analyze relationship between current increment off-limit voltage. The among voltage, exchange derived, can suppressed adjusting injected storage. Through case analysis, it verified that reduce nodes, effectively deviation, active loss.
