This paper presents a single phase standalone two stage photovoltaic (PV) system using seven level inverter. The first stage of conversion in the proposed system uses basic boost converter which ensure Maximum power point tracking(MPPT) and inverter dc bus voltage regulation. A hybridised seven level inverter with less number of components is used as the second stage of conversion that provides ac voltage of required magnitude and frequency. The modulation scheme used for the inverter is level shifted multi carrier pulse width modulation (LS-PWM). A central controller is designed to maintain the dc bus voltages within the reference band irrespective of variations in solar irradiance and load demand. The validity of proposed inverter in PV system is verified through simulation.

High voltage DC Transmission has been alternatively used for large amount of bulk power point to point transmission over long distance. Recent advancement in converter technology has further increased the power carrying capacity of transmission even more. Most of these projects uses Earth electrode as a return path, during the operation DC ground potential rises which sometime has adverse effects on buried objects. Most of the HVDC Projects are Bipole type, first only one pole is built and run which is analyzed and after successful operation further paves a way for second pole or both the poles are built simultaneously Paper suggest dedicated metallic return instead of earth return. Modelling of equipments is done used in UHVDC transmission. UHVDC Transmission model with metallic return is built on matlab and studied. A fault on metallic return is simulated. Simulation results are studied and conclusion are made.

This paper presents a high performance, energy efficient implicit pulsed triggered flip flop based on direct coupled pass transistor (DCPT) approach. This approach directly couple input D to output Q of the flip flop to alleviate the worst case delay. It reduces input to output travelled path hence reduces D-to-Q delay and power consumption. It also includes an extra NMOS for latch designing to reduce the crossbar current. The simulation results presented are obtained by using SAED90nm CMOS technology with supply voltage 1V at 25°C temperature. It operates at 500MHz of clock frequency. By this technique it improves D-to-Q delay by 2% and power-delay-product by 22% for the proposed implicit pulsed flip flop.

An innovative approach to Guidance and Control of Spacecraft Docking System is introduced. Rendezvous and docking or berthing (RVD/B) is a key operational technology, which is required for any mission involving more than one spacecrafts, which successively bring the active vehicle (chaser) into the vicinity of, and eventually into contact with, the passive vehicle (target). A translational exponential Guidance plan is proposed based on the relative range of chaser spacecraft with respect to target. Optimal control loops are developed and simulated using integral LQR strategy to control the relative translational motion between the spacecraft and the space station with minimized thrust profile.

Short term load forecasting plays a vital role in the daily generation, efficient power system planning, unit maintenance, determining unit commitment and secured power system operation. There are number of approaches for short term load forecasting but it is observed that time series approach is most feasible and provides more reasonable accurate forecast. The present paper discuses the Autoregressive (AR) approach of time series analysis for short term load forecast for Tamilnadu (India) load data. The time series Autoregressive gives better forecasting results for 4 to 6 Hours ahead.

Many researchers have analyzed and gave mathematical equations for the motion of the kite. Different mathematical models for the estimation of kite power has been made by Lloyd, Houska, Argatov I. et al., Jerome Marchand, Pauli Rautakorpi et al. between 1980 to 2013. However in their models for estimation of power and maximum power from kite, they have considered density as constant and is equal to the density of air at the sea level (density of air equals to 1.225 Kg/m3). In this paper, effect of air density on kites flying at high altitude was considered and calculations were made for the estimation of maximum power with air density at the sea level and the air density at the flying height of the kite. For this purpose data given by Pauli Rautakorpi et al. has been considered for estimation of maximum power of the kite. Results were compared for each of the five models, density being constant and density varying with height of the kite. All the five models are compared each other for maximum power with actual air density.

Environmentalist fraternity puts in myriad of great effort to mitigate environmental hazard caused by energy craving industries. Solar energy is the best clean alternative energy resource. During shading condition arrays can be treated as an asymmetrical DC source for multilevel inverter, based on insolation level, sets of PV panels are formed to act as DC source. During shading condition, based on insolation level sets of PV panels are allocated to multilevel inverter to as asymmetric source. With the growing research in multilevel inverter there are many topologies have been conceptualized which are having advantage over the conventional inverters. By allocating as asymmetric source the MPPT complexity can be reduced, also with lesser source higher number of levels can be synthesized. The focus of study presented here is toward the exhaustive analysis of conventional and novel cross connected source MLI topologies with reduced count for asymmetric source configuration for PV application, as all cross connected source MLI cannot be implemented for asymmetric source configuration. For the purpose of comparative analysis universal modulation scheme is implemented which enables the switches to operate at fundamental frequency and the results are simulated on MATLAB/Simulink platform.

In recent years, implementation of smart grid technologies has been a prime focus in many countries. To have an accurate and precise information of vital power system parameters, PMUs play a major role in the wide area monitoring, protection and control (WAMPAC) of a smart grid. The placement of phasor measurement units (PMU) in electric transmission system has gained a lot of importance. This paper addresses the various aspects of optimal PMU placement using binary integer linear programming(BILP). Cases with and without zero injection buses have also been considered. Minimum PMU placement problem may have multiple solutions, therefore, two indices viz. BOI (Bus Observability Index) and SORI (System Observability Redundancy Index) have been proposed to further rank these solutions. Results on IEEE 14, 24, 30 and NE 39 bus systems have been presented. Simulation results show that the proposed algorithm can be used efficiently in optimal PMU placement.

International reports show about 25 to 35% energy saving potential in commercial buildings. Many buildings in India, situated in different climatic zones are energy inefficient since they were not constructed following energy conservation building codes and techniques of solar passive architecture. It is impractical to redesign and reconstruct such buildings. In such cases retrofitting of utilities provides a cost effective solution than going for altering the existing building structures. The aim of this paper is to present the results generated from a detailed energy audit study conducted in an office buildings to propagate the awareness of energy saving potentials in Indian buildings. Based on data collection and measurement undertaken, the present case study envisages many energy-saving measures to be considered for implementation towards achieving the energy saving potential in the identified areas. The identified areas were Air conditioning, Lighting, UPSs, Power factor improvement and installation of Energy Management System (EMS). The analysis revealed that the public office building in which the detailed energy audit was carried out has the annual energy saving potential of 231656 kWh, in terms of cost saving; it would be Rs. 16.2 Lakhs. In order to achieve this benefit, it requires one time investment of Rs. 27.5 Lakhs, resulting the payback period of 1.7 years.

(College of Engineering, Pune) COEP-MICROGRID, project by the students of COEP, Pune aims at establishing a microgrid in the college campus. Proposed microgrid has a AC-bus and DC-bus, interconnected together with a tie line DC-AC converter. AC-bus is connected to wind power plants, pico-hydro plant, STATCOM, local AC-loads. In order to maintain required power quality, a low THD on the AC bus side is required. Space vector pulse width modulation (SVPWM) technique is used to drive 2-level voltage source inverter. Microgrid has intermittent generation on DC BUS. Control strategies are so designed as to regulate power and maintain the demand supply balance between DC BUS and AC BUS. To start with, we discuss the basic philosophy of SVPWM and also the design and implementation of its algorithm on a Digital Signal Processor for its generation. The basic architecture of the PWM modules of the DSP is explained and the specific use of the registers in those modules to generate SVPWM is elaborated. The inverter is simulated with the existing architecture of COEP-microgrid and its response in various microgrid scenarios is discussed. This paper also describes implementation of the designed inverter and the corresponding results.
