A novel approach is anticipated in this paper for optimal feeder reconfiguration and placement of DG units in distribution system with an objective of reduction of real power losses while satisfying operating constraints. Selective Particle Swarm Optimization algorithm (SPSO), modified version of Binary Particle Swarm Optimization algorithm, is used to obtain reconfigured distribution network. A novel...
Offshore wind farms are becoming an attractive solution for wind power in many developed countries. The voltage source converter (VSC) based multi-terminal high voltage direct current (MTDC) transmission system is an attractive technical option to integrate these offshore wind farms with the onshore grid due to its unique performance characteristics and reduced power loss via extruded DC cables. In...
This paper presents an approach for performance analysis of an induction motor utilizing the characteristics of slip power recovery schemes (SPRS). The performance is analyzed by using a three phase bridge recovery inverter without chopper and inverter with chopper. The simulation test for a 5.4 hp wound rotor induction motor is carried out on MATLAB/SIMULINK environment. The results of simulation...
Worldwide, wind energy is accepted as one of the foremost developed, cost-effective and proven renewable energy technologies to satisfy increasing electricity demands in an exceedingly sustainable manner. This paper investigates the fast AC fault recovery capability, fast and independent control of active and reactive power of the HVDC Light transmission system. These capabilities are most desired...
Currently, converter control is one of the major fields of present day research works in the area of HVDC Light transmission systems. In this paper, fuzzy logic controller is utilized for controlling both the converters of the HVDC Light transmission systems. The space vector pulse width modulation (SVPWM) concept is also used for better DC bus utilization and harmonic reduction. The proposed controller...
In an open accessed transmission system, the costs of each ancillary service will be unbundled. This paper presents two methods, i.e., a value based approach and tracing method of allocating the cost of reactive power purchased by contract or from a bidding market. These methods have gain importance as their solutions help in evaluating a fair and transparent tariff plan. The applicability of these...
Photovoltaic power plants pose some challenges when integrated with the power grid. The PV plants always focus on extracting the maximum power from the arrays. This makes the PV system unavailable for helping in regulating the grid frequency as compared to conventional generators. The objective of this paper is to introduce a pseudo power point tracking which provides frequency regulation functionality...
