Abstract Recent development in the small scale power generation using distributed energy resources combined with application of power electronic systems initiated the researchers to the concepts of future power generation technologies such as microgrid. The paper presented involves the control techniques required for microgrid operation and implementation of a simple control strategy in a micro...
This paper presents an investigation of different islanding detection techniques which focus on operating parameters. These parameters are to decide whether the system will be islanded or not. The process is based on measuring the voltage, frequency and phase angle at the point of common coupling. The rate of change must be integrated to distinguish the changes in the system, the rate of change...
This paper presents an artificial neural network (ANN) based method for islanding detection of distributed synchronous generators. The proposed method takes advantage of ANN as pattern classifiers. It is capable of identifying the islanding condition based on samples of the voltage waveform measured at the distributed generator terminals only, which is an important advantage over other ANN-base...
In order to prevent the potential frequency instability due high Power Electronics (PE) penetration under an unintentional islanding event, this paper presents a novel microgrid scheduling approach which includes system dynamics as well uncertainty associated with renewable energy resources and load. Synthetic Inertia (SI) control is applied regulating active power output of Inverter-Based Gene...
Active distributed generations (ADGs) are more prevalent near consumer premises. However, the ADG penetration contribute a lot of dynamic changes in power distribution networks which cause different protection and control issues. Islanding is one crucial problems related to such ADGs; on other hand, islanding detection also challenging aspect. Therefore, an extensive review real-time depiction ...
In modern power systems the penetration of renewable energies has been growing dramatically. The combination of renewable energy and energy storage is seen as an opportunity to better exploit the intermittent and uncertain local generation in distribution systems, especially in the case of islanding. The main goal of this paper is to keep the load and generation units on-line under islanding co...
In this paper a passive Neuro-wavelet on the basis of islanding detection procedure for gridconnected inverter-based distributed generation has been developed. Moreover, the weight parameters of neural network are optimized by Interactive Honey Bee Matting optimization (IHBMO) to increase the efficiency of the capability of suggested procedure in tendered problem. Islanding is the situation whe...
Nowadays, high penetration of Distributed Generations (DG)s in power systems caused some protection issues. One of these issues is unintentional islanding. As regards IEEE 1547 standard, this situation must be recognized immediately, and DG must be separated from the load in less than 2 seconds. In this paper, to detection of islanding in an inverter-based distributed generation, a new hybrid m...
in recent years, based on the growing importance of clean energy in comparison with conventional energy production from fossil fuels, dg systems are gradually becoming more popular all over the world. these resources solve many problem of system. however, these resources create some other problems too. one of the most problem of dgs is unwanted islanding. this paper addresses reliable passive i...
