An Online Preventive Control Method for Power Flow Unsolvability

LIU Mingsong1, WU Wenchuan1, ZHANG Boming1, WU Sunong2, LIU Yingshang3(1. State Key Lab of Power Systems, Department of Electrical Engineering, Tsinghua University, Beijing 100084, China;2. Dispatch Center of Jiangxi Power Grid, Nanchang 330077, China;3. Southern China Power Grid Company, Guangzhou 510623, China)  
The function of static state security analysis for the traditional energy management system (EMS) is enhanced, and a static state security early warning and preventive control subsystem is designed and implemented. The subsystem can evaluate power system operation’s security level and identify insecure cases in real time. Further more, countermeasures for the insecure cases are also given. The problem of power flow unsolvability due to heavy load for certain contingencies, which represent the most severe cases, is investigated. Based on the minimum mismatch function and successive linear programming method, a practical algorithm is developed to restore power flow from unsolvability. A digital simulation on an actual provincial power system is made to demonstrate feasibility and applicability of the method proposed. The method proposed has been embedded in an early warning and security countermeasure system running in a control center of a provincial power grid.
