This paper presents a design and simulation of a controller circuit for Power Factor Correction applied to BLDC Motor Control. To achieve accurate and dynamic performance from a BLDC motor, it is usually fed from a Voltage Source Inverter (VSI). Such drives have to deal with problems in power quality and poor power factor at AC mains input as they include a diode bridge rectifier. To overcome such problems and provide faster dynamic performance a power factor correction One Cycle Controlled Ćuk converter is proposed to feed the Voltage Source Inverter based BLDC motors. The Ćuk PFC converter inherits many advantages like low output current and voltage ripple, near unity power factor with simple control. The One Cycle technique provides excellent power source disturbance rejection, fast dynamic response, automatic switching error correction and robust performance.

A consistent research is being carried out in studying Power System stability as more and more renewable resources are replacing conventional generation. It becomes easier to integrate renewables to the grid because of the advancement in power electronics devices. Such huge amount of penetration can cause severe problems to stability of power system. Hence this paper analyzes the influence of large size solar and wind resource on small signal stability. IEEE 14-Bus system has been chosen as a base case. Eigenvalue analysis is performed on base case and afterwards with the replacement of conventional generation by equivalent size of renewables. It is observed that use of combination of renewables has a better damping than alone. The simulation results confirms and demonstrates the same. The simulation models are developed and analyzed in PSAT software package.

In the present day scenario the energy demand is going on increasing. It is expensive to import electricity from the generation far from load centers because of the cost of power loss. It is therefore more economical to use electricity generated by local distributed generators. In this paper power generation from wind, Combined Heat Power (CHP) and utility for a complete day is considered. This paper discusses different methods like Simple Additive Weighting (SAW) method, Weighted Product (WP) method and Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) multi-criteria decision making technique to evaluate the optimal generation of a particular day. The Analytic Hierarchy Process (AHP) method is used to verify the weights' selections. The results obtained by the multi-criteria evaluation using the presented methods, gives the possibility of identification and evaluation of the optimal generation in a particular day.

The objective of this paper is to analyze Southern Regional Grid of India(SRGI). The main focus is to stabilize SRGI from the worst possible fault scenario, for which a comprehensive study of SRGI is done with the help of PSAT. The power system is reviewed with main focus on stability and power system modeling. The main concern is to maintain integrity of the system during disturbance so that whole system remains intact with all the parameters bounded within limits. Transient stability of the system is thus thoroughly studied and appropriate measures are suggested during occurrence of any disturbance. Primary contributions of this work include transient state analysis of the system for evaluation of the effects of limitations on system stability, analysis of worst case scenario, and provision of appropriate measures to avert such a scenario, with the help of advanced controllers such as TCSC(Thyristor Controlled Series Compensator), AVR(Automatic Voltage Regulator).

As compared to conventional inverter topologies like diode clamped and capacitor clamped inverters, the cascaded multilevel inverter has lesser harmonics as well as lower switching stress. The cascaded topology has more number of power switches leading to greater heat losses, larger size, higher cost and more gate drive circuitry. The proposed configuration contains less number of switches and produces lesser harmonics in the output voltage than the cascaded topology. A comparison between four different types of pulse width modulation (PWM) techniques, namely, In-phase disposition (IPD), Anti-phase disposition (APD), Carrier Overlap (CO) and Variable Frequency (VF) PWM methods, has been done. The results have been verified through simulation study in MATLAB/Simulink in order to select the best PWM method that provides minimum THD in the output voltage. An LC filter has been designed to improve the harmonic profile.

Renewable Energy Sources (RES) based Distributed Power Generation use Power Electronic Converters for grid interfacing. This paper deals with a multiobjective control strategy for a current controlled three phase Distributed Generation (DG) inverter. The DG inverter incorporates active filter functionality in forward and reverse power flow modes when connected to a nonlinear load. The multifunctional grid connected inverter (MFGCI) can compensate for load current harmonics, load unbalance and load reactive power demand with closed loop active power control. The proposed closed loop power control scheme achieves accurate power tracking with zero steady state errors under ideal and non-ideal supply conditions. A hysteresis band current controller is used to generate the switching pulses for the interfaced inverter. Extensive simulation studies are done in MATLAB/Simulink software to validate the effectiveness of the proposed control strategy.

The development of far-offshore wind farms and other large-scale renewable energy sources at long distances from load centers will rely on HVDC transmission. Due to the capability for operation in isolated AC grids and integration into multi-terminal DC grids (MTDC), Voltage Source Converters (VSCs) are becoming the preferred technology for HVDC systems. However, most HVDC transmission schemes are currently constructed as point-to point connections, and there is not yet any clear standardization of voltage levels. Thus, DC/DC converters will become necessary if existing or emerging HVDC links should later be interconnected into MTDC configurations. DC/DC converters might also be needed for power flow control in meshed MTDC grids. In this paper, the general requirements for DC/DC converters in different MTDC grid configurations are briefly analyzed before particular attention is dedicated to converters without galvanic separation for power flow control in meshed MTDC grids. The control and operation of a 4-quadrant DC/DC converter for power flow control with voltage ratio close to unity is then analyzed and demonstrated by simulations in a 4-terminal configuration based on the Cigré DC grid test system.

This paper investigates the impact of static synchronous series compensator with energy storage (SSSC-ES) on Hopf bifurcations of Subsynchronous resonance (SSR). The effect of injecting real and reactive voltage by SSSC-ES on SSR is investigated using bifurcation analysis. The IEEE first benchmark model with static exciter and power system stabilizer is considered for the analysis. The results obtained are validated by eigenvalue analysis and transient simulation. The effect of adding SSSC-ES into the power system on the stability boundary is analyzed.

This paper focuses on grid connected PV inverter incorporating the improvement of power quality issues in its controller design. Proportional resonant (PR) controller is used for eliminating steady state error and for the fast dynamic response. A repetitive controller is used for tracking periodic reference signals and to compensate harmonic disturbances. To attain low THD and quick steady state process, feed forward approach is implemented in controller design. The stability of the voltage and current controller is examined in bode plot. Phase locked loop (PLL) synchronization technique with LCL filter is also examined. A single phase Grid connected 3Kw PV inverter is modeled and simulated in MATLAB/Simulink/PLECS environment with the accurate results in its waveform.

For the development of smart grid more and more distributed generation like wind, solar, fuel cell are introduced to the distribution networks in the power systems. Among them wind power generation is identified as the most advantageous and promising source for the future. Wind resource assessment and analysis is a crucial step in gauging the potential of many areas to produce electrical energy. After analyzing the potential, identifying a suitable turbine for a potential site is very significant in wind energy conversion system (WECS). Usually the turbine selection for a potential site is done on the basis of capacity factor, which is the ratio of the average power output to the rated power of the turbine. The intermittent nature of wind calls for its attention for reliability evaluation to integrate the same to the conventional system. The commonly defined reliability indices like Loss of Load Expectation (LOLE), Loss of Load Probability (LOLP), Expected Energy Not Supplied (EENS) give indication about the insufficiency of the power generation to meet the load, but it does not give indication about the consistency of operation. A new reliability index, Turbine Reliability Index (TRI) is proposed to evaluate the performance of turbines in the selected sites. The wind data of a potential site, Kayathar in Tamil Nadu in India was collected for the analysis. Along with the capacity factor, which is the basis of selection of a turbine, if we include the newly proposed index also for the selection of a turbine for a particular site, the performance of the wind energy conversion system can be improved.
