With regard to the interval low-frequency oscillation problems in large-scale interconnected power system, a design method based on Fruit Optimization Algorithm (FOA) for the wide-area time-delay damping controller is proposed in this paper. Systems such as the New England 10-generator 39-bus system is employed to validate the effectiveness of the method presented. The system is linearized at first,...
The practical economic dispatch (ED) problems have many non-convex characteristics, which makes the searching of the global optimum difficult when using traditional mathematical methods. This paper presents a novel hybrid algorithm (HA) to the ED problems based on the particle swarm optimization (PSO) technique and differential evolution (DE) algorithm. Since the standard PSO has the adversity of...
To solve the order choice problem in Prony algorithm, active power or voltage signals are usually used by Prony algorithms based on singular values decomposition-total least square (SVD-TLS). Because of the difference in choosing the standard parameters in SVD-TLS method, a new improved Prony algorithm is presented. The new method uses two indexes-- dynamic variation ratio (DVR) and signal to noise...

Wide-area Measurement System can retrieval the real time dynamic and static information of the large scale power system under the same time reference, helping to resolve the problems of the dynamic analysis and control for an interconnected power system, especially the low-frequency oscillation. However, communication delay is a non-ignorable factor for the stability of wide-area control. In this...

A wide-area adaptive supervisory controller (WAASC) to enhance the damping of inter-area oscillations of multi-machine power systems using wide area measurement system (WAMs) is proposed. A damping controller based on the mixed-sensitivity linear matrix inequality (LMI) approach with pole-placement restriction is designed. WAASC uses the input information from located phase measurement units (PMU)...
