Renewable energy sources are becoming more and more important for power systems. With increasing sizes and a mandate to operate as financial entities seeking to maximize benefits in an electricity market, power systems require highly effective planning tools. In this paper, an optimal capacitor planning method based on optimal power flow is proposed for a power system with wind generators and PV arrays...
In this paper an alternative method is provided to analyze typical un-symmetrical faults in a power system. It uses equivalent sequence current sources to represent the faulty point currents. Then superposition principle is introduced to decompose the three-phase power system with an un-symmetrical fault into three sequence networks with respective equivalent sequence current source connected. The...
This paper endeavors to present a comprehensive summary of the causes and effects of three-phase unbalance and discusses the energy efficiency in the balance condition and the unbalance condition. To correct the unbalance problems, a new topology structure of SVC is proposed. The energy efficiency is analyzed by an actual experiment with the compensation of the new SVC. And the experimental result...
In the present study, we proposed a new schedule of the lighting control at Kogakuin University located in Shinjuku. In addition, verification about an energy-saving effect on the lighting schedule management is executed. Consequently, it becomes clear that the reduction of the electric energy will be achieved if the classroom lighting is managed by the proposed schedule.
To determine the presence and location of faults in a transmission by the adaptation of protective distance relay based on the measurement of fixed settings as line impedance is achieved by several different techniques. Moreover, a fast, accurate and robust technique for real-time purposes is required for the modern power systems. The appliance of recurrent neural network in transmission line protection...
This paper proposes Taguchi's method for design of experiments to test market splitting algorithm of an electric power exchange. Such a mechanism is required because price-volume pairs of a trader are usually bound by confidentiality requirement and hence not available as test data. We also propose a novel and simple market splitting heuristic considering congestion management problem in a meshed...

For every state utility in India, along with state owned generation there are two major sources of power available to fulfill the load demand. They are, Central Govt owned generation i.e. central sector generation and power purchased from power trading market. For optimum scheduling, additional sources of power need to be incorporated in the generation scheduling algorithm, along with their individual...
This paper investigates the application of SVC hybrid controller for improving damping inter-area modes of oscillations. The proposed controller comprised fuzzy logic proportional and derivative controller with the conventional proportional and integral controller (FUZZY PD+PI) turn by genetic algorithm techniques. The proposed control scheme implements the characteristics of the GA's global optimization...
India is struggling to meet the electric power demands of a fast expanding economy. Restructuring of the power industry has only increased several challenges for the power system engineers. A major chunk of the power losses is a direct derivative of the poor management of distribution networks. Distribution automation (DA) has been aimed at reducing losses, and improving reliability and financial...
