Research on Reactive Power Optimization Voltage Regulation Strategy for Active Distribution Networks

To address the issue of frequent node voltage exceeding limits due to insufficient or excessive reactive power support capacity in long-term operation of distribution networks, as well as the increased difficulty of centralized optimization scheduling, a reactive power zoning voltage regulation strategy for active distribution networks is proposed. This paper relies on electrical distance for zoning and constructs a reactive optimization model aimed at minimizing the active network loss and equipment output cost of the distribution network. A parallel synchronous ADMM algorithm is proposed, which couples and regulates each zone by scheduling reactive power equipment in the distribution network. Finally, simulation verification is conducted on an IEEE33-node distribution network.
