Heating Systems by Solar Photovoltaic Power Generating with Low Cost
Jiang Zhijian,Zhou Dan,Yin Zhenyong(School of Electricity and Information Engineering,BUCEA Beijing 100044)
In this paper,low-cost heating scheme of photovoltaic solar with grid as an auxiliary power is proposed.As the heating in winter has the low power supply quality and the great demand for power with long-term stability,the battery of the general photovoltaic power generating system is eliminated.During the heating process,the photovoltaic solar system pursuits the maximum utilization of solar energy,and grid only plays a supplementary role. The power of the solar-power output and the grid rectifier output are jointed at the DC bus to supply for the standard heating appliances via the inverter.The cost will be further reduced if the power of DC bus is directly given to special resistive heating appliances with no inverter.
