要約(日本語): Energy storage systems are being installed into the power systems in response to the massive integration of renewable energy generation. Energy storage systems installation is also beneficial for securing voltage stability, which faces to some practical difficulties due to line contingency occurrence and more stressed loading conditions. This paper proposes a multistage-based preventive scheme considering operational strategy of energy storage systems. A stochastic security-constrained optimal power flow considering uncertainties in renewable energy generation, operation of reactive power compensator, rescheduling of energy storage systems operation and load shedding are hierarchically implemented in the proposed method. The rescheduling of energy storage systems operation increases the network flexibility to ensure voltage stability and security for uncertainties in renewable energy generation and line contingencies, especially in the stressed loading condition. Several case studies based on a modified IEEE 57-bus test system are carried out to demonstrate the effectiveness of the proposed method. The simulation results show that the proposed method can make an important contribution to improve voltage stability and security performance under severe conditions.
