Distributed generation integration in the distribution system is a challenging issue in context of optimal placement of DG and improvements in the system operation in terms of losses reduction and voltage profile improvement. In this paper, The main objective of the paper is: (i) finding out the optimal DG location and size using various techniques at unity and 0.9 pf lag, (ii) calculation of total energy losses and cost of active and reactive power supplied by the DG and (iii) comparison of sensitivity and optimization based techniques. The analysis has been carried out for an IEEE 33 radial bus test system.

Power converter is an important technology in industrial process, train traction and ship propulsion powered by different electric drive system. In this paper, sub-multilevel inverter is used to obtained multilevel waveform which uses reduced number of switches in comparison of other conventional multilevel inverter for same output levels. A comparison of THD produced in the output voltage generated using 7 level sub-multilevel inverter by employing two switching schemes i.e. nearest level control and selective harmonic elimination have been made. Simulation studies in MATLAB/SIMULINK environment have been carried out for 7 level sub-multilevel inverter. Based on simulation results, it is observed that THD in output voltage is less when selective harmoni elimination technique is employed as compared to nearest level control technique.

Recent advancements in shipboard power system have focused on Medium Voltage DC Distribution System in Navy Ships. This system requires the use of high input to output voltage DC-DC converters to act as buffer between the MVDC bus and the load centers within the ship. The load lines to these converters which often involve other DC-DC converters and inverters, will be powering complex machinery and other sensitive systems. So, proper regulation and control of the DC-DC converter is necessary. This paper proposes a Fuzzy Logic Controller implemented on Buck Converter used in an MVDC Distribution System and compares the performance with a conventional PI controller. The simulation results using MATLAB illustrates the usefulness of FLC over the conventional PI controller.

The conventional sources and central generation systems are becoming outdated. Moreover, they don't seem to be capable of fulfilling the growing energy demand in future and are major cause of pollution and Green House effect. In recent years, Renewable Energy and Distributed Generation systems have become a hot topic and a lot of research is carried out in these fields. In this paper, a renewable energy micro-grid containing PV and wind energy sources with Micro-Turbine, Fuel cell, Battery and Grid as backup sources is studied. The total operational cost and emissions of the micro-grid(MG) are minimized to obtain the optimal power schedule of a day. For this purpose, a mixed integer non-linear programming (MINLP) method is used and results are compared with other programming algorithms like Particle Swarm optimization (PSO) and Genetic algorithm (GA).

The Static Synchronous Compensator (STATCOM) is one of the most widely used Flexible AC Transmission System (FACTS) device which is based on a voltage source converter with a dc link capacitor. This paper presents the mathematical modelling of STATCOM in dq domain, with the Q-Vdc controller to control the reactive power flow in the system and to maintain the dc voltage at a constant value. The control of the voltage source converter(VSC) is achieved by controlling the duty cycle of the inverter devices in Park's domain (dd and dq). Design, analysis and comparison of Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) controllers for this scheme is presented.

The fruitfulness of the microgrids' installation depend upon the design of effective control system that can commendably handle various uncertainties such as renewable energy intermittencies, dynamic variations of nonlinear/reactive loads, disturbances during connect/disconnect with utility grid, faults, inverter failures, etc. There are many simulation tools available for microgrid modeling and testing its controllers before the actual system is deployed. Howbeit, for best validation, it is always recommended to test in a real-time rather than in simulation. But, testing with real equipment is not affordable for research purpose. Further, many real-time simulators such as RTDS, RT-Lab, eMEGAsim, Typhoon-HIL, HRTSim, dSPACE, etc., brought a concept called hardware-in-the-loop (HIL) setup, that possess the advantages of both simulation and experiment. However, all these existing HIL setups are still expensive to use them for the research conducting in academic institutions. With this intent, this paper suggests some alternative and low cost HIL setups with COTS units usually available in laboratories of academic institutions such as MATLAB, LabVIEW, PLC, RTU, SCADA to simulate and test the microgrids in real-time.

An Ant Colony Optimization (ACO) based Fractional Fuzzy PID controller is proposed in this paper. The resulting controller Ant Colony Fractional Fuzzy PID (AFrFPID) Controller incorporates the characteristics of the Ant Colony System and Fuzzy Control for controlling integer and fractional order plants. Fractional Order PID (FOPID) controllers show better performance for systems that have non-linear and time varying variables. However; the complexity of designing FOPID parameters is increased due to increase in tuning parameters (from 3 to 5). To obtain an initial estimate of these five parameters; the bio-inspired ACO algorithm is used. Ant Colony Optimization is a population based meta-heuristic technique which from the behavior of real ant colonies to find solutions to discrete optimization problems. Fuzzy Control is used to further fine tune the parameters for better control. MATLAB Simulations are presented and the performance of the AFrFPID controller is validated.

This paper proposes a new technique of state estimation (SE) for electric power systems. In the proposed scheme, the Phasor Measurement Units (PMU) are first placed optimally using Greedy Algorithm for cost reduction, while complete observability of system is also obtained. The SE uses a linear measurement model to obtain the estimated states directly, without any iteration, thereby improves the quality of the estimated data base. To reveal the efficacy of the proposed scheme it has been tested on standard IEEE 5-bus, 14-bus, 30-bus, 57-bus and 118-Bus test systems and the test results are presented.
