Extreme disasters seriously threaten power system security and stable operation. Power system resilience is an important means to evaluate the system response to low probability and high impact events. This paper proposes a resilience enhancement strategy based on cyber physical power system to cope with extreme natural disasters and restore the power system. At first, a defense framework for natural disaster is given to show stages and techniques used in resilience enhancement strategy. Secondly, a zone division based power flow adjustment method is proposed to adjust the transmission power with high failure probability, which can reduce the risk of cascading failures. Finally, two resilience evaluation functions considering load restoration and equipment restoration are proposed respectively to guild collaborative communication lines and transmission lines restoration. Simulation results of the New England 39-bus test system demonstrate the effectiveness. |
