Numerical Modeling, Simulation and Validation of Hybrid Solar Photovoltaic, Wind Turbine and Fuel Cell Power System

The objective of this paper is to design a multi-input dc-ac inverter integrated photovoltaic array, wind turbine and fuel cell in order to simplify the hybrid power system and reduce the cost. The output power characteristics of the photovoltaic array, wind turbine and fuel cell are introduced. The operational principle and technical details of the proposed multi-input dc-ac inverter is then explained. The proposed inverter consists of a three input flyback dc-dc converter and a single phase full bridge dc-ac inverter. The control strategy for the proposed inverter to distribute the power reasonably to the sources and it achieved a priority of the new energy utilization is discussed. This multi-input dc-ac inverter is capable of being operated in five conditions and power delivered to the ac load can be either individually or simultaneously. First to third condition occurs when the power delivered from either renewable energy sources individually, fourth condition happens when power is demanded from two sources simultaneously, and finally when power are available from three sources simultaneously. The proposed inverter has been simulated by employing NI Multisim 12.0 circuit simulator.

Climatic Cycle

In this paper, the performance analysis of a floriculture greenhouse having a fan-pad ventilation system is presented. The greenhouse is powered by integrated solar photovoltaic–electrolyser–fuel cell system. Electrical energy is generated in an array of roof mounted solar photovoltaic modules and energy back up is provided through a combination of polymer electrolyte membrane (PEM) electrolyser and fuel cell system. Excess energy, after meeting the requirements of greenhouse during peak sunshine hours, is supplied to an electrolyser bank to generate hydrogen gas, which is consumed by PEM fuel cell stacks to support the power requirement during the energy deficit hours. The performance of greenhouse and its power system are analyzed for representative days of different seasons of a climatic cycle. The study shows that temperature inside the greenhouse can be maintained within permissible limits for cultivation of target flowers like varieties of rose using fan-pad ventilation. From the performance analysis of power system, it is observed that there is net accumulation of hydrogen gas for representative days of all seasons of a climatic cycle, the daylong cumulative gas generation being maximum in the month of December. The study reinforces the viability of a standalone, grid-independent greenhouse powered through solar energy.

Viable Option

The application of greenhouse technology for cultivation of flowers, vegetables and horticultural plants is rapidly expanding worldwide. But at present the requirement of grid connectivity imposes a restriction on the emanation of this technology to areas which are remote. In a developing country like India, where a significant number of villages are yet to be connected to any national or regional grid, this restriction assumes considerable significance. Due to abundant availability of solar energy in the plains of Indian subcontinent, its use in powering a greenhouse provides for a viable option. But due to the intermittent availability of solar energy, the provision of some form of back up arrangement to power the greenhouse becomes necessary. In the present paper a model for the power system of a greenhouse powered by solar photovoltaic system is presented and the back up arrangement is provided through a combination of electrolyser fuel cell system. The presented model shows that this integrated system comprising of greenhouse-solar photovoltaic module-electrolyser & fuel cell will provide a viable option for the design of stand alone greenhouses.
