This paper presents a modeling approach for analysis of Torque, Current and Voltage characteristics. Distributed Generation systems are becoming more popular everyday due to its greater efficiency and eco-friendly behavior. Another advantage of DG System is that it can operate independently or can be connected to a Grid system. In this paper a microturbine based DG System is created using MATLAB and the output is thus connected to the Permanent Magnet Synchronous Generator (PMSG) and the characteristics for Stator Current, Electromagnetic Torque and Rotor Speed are plotted down. Furthermore, the Voltage and Current is also measured across an isolated Resistive Load.

In spite of India holding the second position in production of fruits and vegetables in the world, about one third of these are wasted in post-harvest. Major chunk of post-harvest losses are attributed to lack of proper cold storage and cold chain facilities. The quality and life of the commodities are determined by their storage conditions. Hence, designing an intelligent cold storage system turns out to be very much essential in order to mitigate the post-harvest wastage of the perishable commodities. This enables remunerative prices to the cultivators in addition to making the commodities available at competitive and affordable prices to the consumers. Based on the technical standards for control atmosphere cold stores temperature, humidity, CO2 level and light intensity level are the essential parameters to be monitored and controlled for maintaining their quality and life. However, currently available cold storage systems in India do not consider controlling of all these essential parameters. With an intention to address this, a wireless sensor network based fuzzy logic controller for monitoring and controlling these essential parameters is proposed here.

Increasing level of environmental pollution, petroleum prices and depleting level of natural resources are major troubles caused by internal combustion engine based transportation system. Hybrid electric vehicles (HEVs) have presented the solution to these problems and are assumed to be future green and sustainable transport medium. HEVs utilizes engine and battery together to give power to the wheels. Since, presence of two sources causes the complexity at architectural level of vehicle, hence requires a judicious power split between them. To split power efficiently between engine and battery, an intelligent energy management scheme is required to be implemented. An efficient power split scheme may consequence in better fuel economy and performance of HEVs. Here, particle swarm optimization based intelligent energy management scheme is implemented and compared with genetic algorithm and dividing rectangle algorithms. Modified state of charge (SOC) estimation method and 1RC battery model are used for simulation purposes in advanced vehicle simulator (ADVISOR).

DC-Link Capacitors are one of the core constituents in many power electronic systems mainly DC-micro grids. They contribute significantly to the overall size. In this paper, a technique “Stacked Switched Capacitor” (SSC) proposed earlier is modified by using an array of electrolytic capacitors and switches as an alternative to a large electrolytic capacitor. The new topology is named “electrolytic SSC” (eSSC) and it effectively reduces the size of the converter. This technique replaces a large electrolytic capacitor with smaller capacitors and an array of switches to mimic the behavior of a large electrolytic capacitor. In this paper, the proposed topology is analyzed and different design requirements are taken into account for the proper functioning of the eSSC. The simulation results are presented and an estimate of the relative volume of the original SSC shows that the proposed eSSC indeed reduces the size by a reasonable amount and it can be inculcated into any system where capacitor bank is required which draws current at line frequency.

The higher shares of distributed generation (DG) sources lead to unpredictable rise in voltage level due to intermittent and stochastic characteristics of DGs. This paper intends to report the online Volt/Var control in a smart grid with multiple DG systems. The objective of Volt/Var control is to recover the network voltages within the admissible limits by coordinating the operation of the DG and the OLTC transformer. Firstly, voltage profile of the system is estimated by remote terminal units (RTUs) placed only at DG node. Next, a direct voltage sensitivity based method is developed to choose best DG for reactive power injection in multiple DG environments. Finally, OLTC transformer is employed in voltage regulation process when DGs reactive power is insufficient for maintaining the voltages within predefined limits. The reported method tested on 12-bus radial distribution network to validate the theory. The reported simulation results show that the presented method effectively maintains network voltages within admissible limits.

Recently the open-access and competitive market power policy has been adopted by the utilities. Now, the electricity consumers are in a position to demand and expect a higher quality of service. The utilities and power providers have to provide a high quality of service to remain competitive as well as to retain or attract the customers. To achieve this goal an efficient power quality (PQ) monitoring and analysis system is required. This paper presents an S-transform based technique for the detection of power system operational events and power quality disturbances associated with these events. The power quality disturbances associated with the power system operational events such as switching on and off the loads, switching on and off the capacitor banks, tripping and reclosing the transmission lines, outage of the generator and utility network has been investigated effectively. The detailed simulation study of power quality disturbances has been carried out in MATLAB/Simulink environment.

The relaying is an important aspect for the protection of transmission lines, generators, bus-bars, and transformers for reliable power system operation. The issue of protection has become critical due to increased grid integration of distributed energy sources. The relaying systems continuously monitor the voltage and currents in the power system and generate commands to isolate the faulty part of the network during the events of power system faults. These faults are common and more frequent in transmission and distribution systems. This paper presents an algorithm based on discrete wavelet transform (DWT) for the detection of power system faults in the presence of solar PV power generation system. The power system faults such as line to ground (LG), double line (LL), double line to ground (LLG) and three phase fault involving ground (LLLG) has been investigated. The current supplied by the solar PV system has been found to be key feature for the detection of power system faults. The study has been performed using a test system and results have been validated in MATLAB/Simulink environment.

This paper presents a strategy for the energy management for a hybrid PV/Wind/Battery (PWB) energy system using the adaptive network-based fuzzy inference system (ANFIS). The energy management system is aimed at reducing the fluctuations of power injected into the grid, which is one of the major problems in the renewable energy systems. Another objective is to maintain the battery state of charge (SOC) within the acceptable limits so that the lifetime of the batteries can be increased. The ANFIS has been used to manage the power among the grid, source and the batteries. The results demonstrate that the ANFIS is rendering good performance and the fluctuations are reduced considerably.

In the modern set up of generation, transmission, distribution and electric power utilization, dc to ac power conversion is a very important technology and multilevel inverter are the best choice for this converion as it has many advantages over two level inverter. In this paper, a new asymmetrical multilevel inverter topology for 7-level inverter is proposed which requires less number of switches, driver circuits and dc voltage sources as compared to other asymmetrical topologies and conventional multilevel inverter topologies. In the proposed topology, six power electronic switches and two dc voltage sources are required for generating 7-level in single phase output voltage. Performance of the proposed topology to generate positive, zero and negative level have been evaluated in terms of Total Harmonic Distortion (THD) in the output voltage using simulation in MATLAB environment. To validate the performance of proposed topology various waveforms and simulation results are presented in the paper. Fundamental switching control technique is used to operate the various switches.
