Abstract

Aiming at the issue that the reactive power compensation of large-scale wind power integration grid mainly focuses on voltage deviation, which can not adapt to the voltage imbalance operation condition, this paper proposes a comprehensive voltage compensation method based on split-phase power flow optimization （SPPFO）. Firstly, a SPPFO model is established, which takes the minimum mean value of voltage unbalance, the minimum mean value of three-phase voltage deviation and the minimum total compensation amount of centralized reactive power compensation equipment as the optimization objectives. After that, an improved multi-objective particle swarm optimization（MOPSO） algorithm is used to solve the optimization model with high performance. Furthermore, for the obtained quasi-optimal compensation schemes as the solutions of SPPFO, the optimal compensation scheme is determined by the combination of order relation analysis method and the technique for order preference by similarity to an ideal solution method （TOPSIS）. Finally, an actual wind power integration grid in north China is taken as a case study to verify the effectiveness of the proposed strategy and the advantages of the proposed improved MOPSO.
