A Wide Area Monitoring System Using Neuro Control Technique for Load Restoration

Abstract: System restoration following a blackout is one of the most important tasks for power system planning and operation. The restoration process returns the system back to a normal operating condition following an outage of the system. With the development of the wide area monitoring system (WAMS) using neuro control technique, voltage can be controlled and power system operators are capable of accessing to more accurate data in the restoration stage after a major outage. In this work, a restorable load estimation method is proposed by employing WAMS to monitor the system parameters in case the newly recovered system becomes unstable again. The concept of power conversion from renewable energy sources is included to compensate voltage sag during addition of new loads are analyzed and simulated using MATLAB. This improves the overall system reliability and avoids cascaded blackout during fault occurrence.
