A hybrid strategy of network reconstruction and voltage control based on N-1 security verification

The existing planning scheme for the distribution network has the drawback of single strategy, leading to the difficulty of meeting the N-1 security operation verification. The paper proposes a hybrid strategy involving network reconfiguration and voltage regulation using distributed photovoltaic to improve the N-1 security verification results of the distribution network. Through case studies, it is demonstrated that this approach can effectively address the problem of traditional methods failing the N-1 security check, thereby enhancing the supply reliability and stability of the distribution network.
