An indirect adaptive fuzzy power system stabilizer (IDFPSS) is proposed in this paper. It consists of A fuzzy identifier and a feedback linearizing controller. The objective is to damp local and inter-area oscillations that occur following power system disturbance. The effectiveness of the proposed technique is illustrated by applying the IDFPSS to a two-area four-machine system that is typical...

In this paper, an evolutionary algorithm-Invasive Weed Optimization (IWO) based power system stabilizer (PSS) is proposed for multi-machine power system. IWO is a derivative-free real parameter optimization technique that mimics the ecological behavior of colonizing weeds. Owing to its superior performance in comparison with many other existing meta-heuristics, it has used to search for optimal...

The impact on the stability of power systems is rising as penetration level renewable energy with sporadic natures rises rapidly grid. However, different types sources (wind, solar) and their combination system varies even same level. This paper concentrates mainly analysis multi-machine connected to various sources. study presents a simple novel control technique named automatic reactive suppo...

-In this paper the concept of synchronous stability is introduced to study the transient stability problem of an operating process for a multi-machine power system. Necessary and sufficient conditions for an orbit of the system to be synchronously stable are obtained. Condition of non-synchrony and control of the synchronous stability are discussed. Key-Words: Synchronous stability, multi-machi...

In this paper, the theory and modeling of large scale photovoltaic (PV) in the power grid and its effect on power system stability are studied. In this work, the basic module, small signal modeling and mathematical analysis of the large scale PV jointed multi-machine are demonstrated. The principal portion of the paper is to reduce the low frequency fluctuations by tuned stabilizer in the atten...

this paper presents a novel indirect adaptive power system stabilizer (pss) via a developed synergetic control methodology and fuzzy systems. fuzzy system is utilized in an adaptive scheme to estimate the system using a nonlinear model. the synergetic control guarantees robustness of the controller and makes the controller easy to implement because of using a chatter free continuous control law...

organic manure plays an important role in the improvement of soil structure by decreasing bulk density and increasing porosity. however, the method of manure spreading influences its beneficial impact on soil structure. in this study, a novel helical manure distributor machine capable of spreading manure with different moisture contents at maximum distribution width was developed and the machin...
