Voltage Optimization Method for Distribution Network Based on Multi Resource Collaboration

With the increasing penetration of distributed generation (DG) in modern distribution networks, voltage regulation becomes a critical challenge. This paper proposes a voltage regulation optimization strategy based on multi distributed resource collaboration, integrating photovoltaics, energy storage systems, and reactive power compensation devices. Firstly, the regulation potential boundaries of each resource are evaluated. Secondly, a multi-resource regulation priority determination and voltage regulation model are proposed. Simulation based on the IEEE 33 system show that the proposed method significantly enhances voltage quality compared to traditional single-resource regulation methods, ensuring that voltage levels remain within acceptable limits across varying loads and PV output fluctuations.
