Security Assessment of Bus Voltages in Electric Power Systems

摘要:Control room operators often deal with stressed system operating conditions and vulnerable networks. They need tools for continuous monitoring of system conditions to detect any untoward situation as quickly as possible. Security monitoring and assessment ensures that planned or unplanned outages do not lead to costly consequences such as loss of non-interruptible loads, equipment damage, and uncontrolled separation. Proposed method employs probabilistic load flow for bus voltage security assessment. Probability distribution and density function of the cumulants of the bus voltages is plotted. With the help of these distributions a fast and accurate contingency ranking for security assessment is made possible. The method has been applied to the IEEE RTS 7-Bus test system which consists of 7 buses and 10 lines as well as to the larger IEEE 24 bus system which consists of 24 buses and 38 lines.
