C. R. Fuerte-Esquivel Universidad Michoacana de San Nicolás de Hidalgo, Morelia, Mexico Abstract A general approach to real-time transient stability control is described, yielding various complementary techniques: pure preventive, open-loop emergency, and closed-loop emergency controls. Recent progress in terms of a global transient stability-constrained optimal power flow is presented, yieldin...

With an increasing number of photovoltaic (PV) power stations integrated into the power grid, a model which is suitable to be used in the power system electromagnetic transient simulation is required. So in this paper, a detailed PV power system model is provided. In the model, the core components, such as PV array and inverter are all considered. Then in a certain case, which contains a PV pow...

In this paper, Automation of a power system fault detection using multi resolution analysis (MRA) wavelet transform is proposed and the various coefficients obtained from wavelet transform are given as an input to the probabilistic neural network (PNN). This PNN will classify and find the nature of fault occurring. Later, the decisions obtained from the output of PNN can be used to tune the pow...

Control Agent Prediction Agent Abstract-This paper proposes transient angle stability agents to enhance power system stability. The proposed transient angle stability agents divided into two strategy agents. The first strategy agent is a prediction agent that will predict power system instability. According to the prediction agent’s output, the second strategy agent, which is a control agent, i...

In this paper, a robust decentralized excitation control scheme is proposed for multimachine power system transient stability enhancement. First, a direct feedback linearization (DFL) compensator through the excitation loop is designed to eliminate the nonlinearitles and interconnections of the multl-machine power system. Then, a robust decentralized controller IS proposed to guarantee the asym...

Abstract— A new development of voltage control scheme for power quality improvement such as voltage sag, swell, harmonics, and transient conditions in three-phase power systems has been proposed. Faults occurring in power distribution systems or amenities can inject the voltage sag or swell. This fault can damage or affect the power transmission and distribution. For sensitive loads, the short ...

The article presents the transients analysis of the substation grounding systems and transmission line tower footing resistances which can affect to the back-flashover (BF) or overvoltage across insulator chain in an HV power systems by using EMTP-RV software. The related transient modeling of the grounding systems is based on a transmission line (TL) model with considering the soil ionization....

Transient stability of a power system is concerned with the system’s ability to remain in synchronism after the disturbance is cleared. Occurrence of a fault in a power system causes transients. The disturbances subjected to the system may be occurrence of fault, sudden change in load etc. This paper describes the improvement of transient stability with phase shift insertion by phase shifting t...

ABSTARCT Transient stability is increasingly important for secure loading. Transient stability evaluation of large scale power systems is an extremely intricate and highly non linear problem. An important function of transient evaluation is to appraise the capability of the power system to with stand serious contingency in time, so that some emergencies or preventive control can be carried out ...
