As per present power crisis small micro-hydro, non conventional plants may be planned to work during the peak demand. Integrated generation and distribution for rural area on fuel availability, small hydro capacity on run of the river, shall improve the availability and reduce energy cost. This paper presents eight case studies of micro hydro plants in rural area of India, Madhya Pradesh, Chattisgarh having different site conditions as on Irrigation canals, Dam toe and return canals of Thermal Power Stations. Calculation of net head and discharge is given. Various types of Turbines and Generators are discussed with their suitability under different head and discharge conditions. The reliability of Power output from the mini/micro hydel power station is found out by river flow and rainfall estimation. Detail economic analysis is also done giving effective measures to reduce the cost. Comparisons of small/mini /micro hydel with other Non-Conventional energy sources are also presented. A simplified model with turbine, Generator and Mechanical Coupling as the major equipments has been demonstrated and its working is been explained. The output of the model has been tested and usefulness of this research is highlighted.

This paper aims an objective to study Economic Analysis of Mini hydel schemes. This study facilitates to take effective measures for reducing the cost which are also given. Analysis of two mini hydel schemes, Bhimgarh small hydel and Chargaon-Jatlapur Mini hydel project in India, constructed on dam toe and canal fall respectively is given. Parameters like cost of Civil work, by pass canal, intake structure and cross regulation has been worked out. Cost benefit ratio and Annual return is calculated. Estimate for electrical and mechanical equipments is prepared. The constraints and problems arising in development of power hydel schemes are known. Comparing with other alternative sources of energy, economics of Non-Conventional energy schemes is given. Because of limited availability of coal and other fossil fuels and for total upliftment of country, growth of remote places is must. Whereas to transmit power to such places is very costly. This gives rise to Pico-hydro Plant that does not require construction of dams and considered as run off river. Hence, simplified model has been demonstrated and working is been explained. The output has been tested and usefulness of research is highlighted.

The use of Photovoltaic (PV) systems is increasing rapidly due to its various advantages. The performance of PV system depends upon in plane radiation and temperature. A PV module is designed in MA TLAB-SIMULlNK using the S-function builder and controlled current source. The proposed PV module enables us to obtain its P-V and I-V characteristics at different temperature and radiations. The main disadvantage of the PV system is its variable voltage. To obtain the stable voltage, the different DC-DC converters are connected with the PV modules. An intermediate dc-dc converter can increase efficiency of the system by providing impedance match between PV system and load. This paper presents the design and simulation of DC-DC converters. In this paper, Boost converter, cascaded Buck Boost, Cuk converter and Single ended primary inductance converter (SEPIC) are modeled in MATLAB and their results are compared.
