ADMM-based Distributed Active and Reactive Power Control for Regional AC Power Grid with Wind Farms

A distributed active and reactive power control (DARPC) strategy based on the alternating direction method of multipliers (ADMM) is proposed for regional AC transmission system (TS) with wind farms (WFs). The DARPC optimizes distribution among WFs to minimize losses TS while tracking reference from operator (TSO), minimizes voltage deviation buses inside WF rated as well collection system. optimal flow (OPF) relaxed by using semidefinite programming (SDP) relaxation branch model used In strategy, large-scale strongly-coupled optimization problem decomposed ADMM, which solved in controller controllers parallel without loss global optimality. boundary information exchanged between controllers. Compared conventional OPF WFs, optimality accuracy operation can be improved. Moreover, efficiently reduces computation burden eliminates need a central controller. protection privacy enhanced. modified IEEE 9-bus two consisting 64 turbines (WTs) validate strategy.
