A laboratory test bench has been setup to determine the dynamic properties of the system and to verify the proposed power flow control principle. Control board prototype has been developed and briefly described. Results of full reference power cycle tests have been summarized.

Simulation and Optimization of Solar Photovoltaic–Wind–Diesel Generator Stand-alone Hybrid System in Remote Village of Rajasthan, India

Abstract: This paper carries the study of an unelectrified remote village physically located at latitude: 25° 6′ N and longitude: 77° 21′ E with an altitude of 275 m above sea level identified as Mahoori of Rajasthan, India, having a population of 217 persons in 41 households with bad footprint on the socio-economic conditions. The hybrid renewable energy source (HRES) paradigm is proposed which includes a combination of solar photovoltaic (SPV), wind generator (WG), diesel generator (DG) and battery with real-time optimal cost based on emission of solar, variations of wind and load profile to meet average-scaled residential load of 97.5 kWh/day. The overall power generation by the scheme is 68,809 kWh/yr having cost of electricity as $0.144/kWh. The techno-monetary features along with improvised varied system structures at 0, 5 and 10% maximum capacity deficiency is calculated. Further research ideas appeared also acknowledged at last.

Shifting from Carbon to Hydrogen Economy: A Case Study of Rajasthan State in India

Abstract: Transportation sector is one of the major contributors for environmental pollution. Exhaust gases released from vehicles are one of the major sources of emissions of greenhouse gases like carbon dioxide. This paper presents the feasibility of CO 2 emission reduction in Kota, India by replacing the present fossil-fuel based internal combustion engine vehicles with hydrogen-fueled fuel cell electric vehicles. Hydrogen is produced by the electrolysis process due to its highest purity hydrogen production and the required electricity is generated by a solar photovoltaic power plant. Total CO 2 emission by 61,402 number of cars of Kota is calculated as approximately 4000 tonnes for an average driving distance of 500 km. 100 cars are taken into account in this paper for a pilot project calculation. 5000 litre of water and 25,183.45 kWh of electricity will be required for enough hydrogen production to run 100 cars. The required size of solar photovoltaic plant will be 5.5 MW and is also simulated by PVSyst software. For conversion of total cars into hydrogen-fueled fuel cell electric vehicle, solar photovoltaic power plant of size 3.5 GW and 3070 kilolitre of water will be required.

10 kW solar photovoltaic — Diesel hybrid energy system for different solar zones of India

Abstract: A 10 kW standalone power generating system is proposed and analyzed for different solar zones of India. The system consists solar PV, diesel generator, batteries and converter. Optimum sizing of diesel generator and solar PV system that fulfills the load demand is obtained by varying the capacity of diesel generator and solar PV system components individually. For system sizing, Hybrid Optimization Model for Electric Renewables (HOMER 3.4.3) is used. HOMER fulfills the system demand using two different methods or dispatch strategy (a) load following and (b) cycle charging. The output of the software for both the methods is compared on the basis of levelized cost of energy (LCOE), power produced and emission of greenhouse gases. On comparison Load Following method is found to be better than cycle charging method of simulation. Simulating the solar PV — diesel generator system using HOMER for different locations namely Chennai, Jaipur, Shillong and Srinagar locations are selected in different solar zones of India. For installation of hybrid energy system Jaipur is found to be better with minimum levelized cost of energy of Rs. 12.681/kWh and Chennai, Srinagar and Shillong follow the order, as Shillong has maximum levelized cost of energy of Rs. 14.205/kWh.

Functionality Testing of Object-Oriented Software Using UML State Machine Diagram

Abstract: This paper proposed automatic test scenario generation technique using UML state machine diagram. We have considered the state machine diagram as input for our proposed parser named XMLtoTS, which generates the Control Flow Graph (CFG) of the system. In this paper, we have proposed algorithm SMTSGA (State Machine to Test Scenario Generation Algorithm) for generating test scenarios. Proposed algorithm SMTSGA generate all test scenarios. The generation of test scenarios is important for test case generation of the system. We have used this process during the design phase of the software development prior the actual testing phase to reduce the cost of and time of testing and later it will also require less effort for testing of the system.
