To ensure the voltage stability of power grid under large disturbances, this paper proposes a voltage stability emergency control coordination strategy based on convolutional neural network (CNN) and long short-term memory (LSTM) network.
The rapid voltage stability emergency control actions must be applied in case of safety damages resulting from continuous abnormal operating conditions. The goal for power system emergency control is to quickly maintain the voltage at an acceptable level after large disturbances.
Therefore, the traditional method of power grid stability control decision-making can not fully consider a variety of factors, making it unable to satisfy the high-efficiency requirements of today's large-scale power grid online security and stability decision-making response.
A main factor that directly imperil the stable operation of power grid is the mismatch of traditional emergency control with ODOP mode. To address the above key issue, the influencing factors of control mismatch is extracted, and the coordination principle between voltage stability emergency control strategies is proposed.
The voltage stability of power grid will deteriorate, and the traditional emergency control strategy may mismatch. The mismatch scenario is set as follows: Increase the renewable energy penetration rate in Qinghai from 60% to 70%.
Emergency control is the control strategy performed to ensure stable and safe running when the power system is seriously malfunctioned. It is usually thought of as the last resort for ensuring the power system operates steadily.
