Highlights This paper reviews the progress made in solar power generation by PV technology. Performance of solar PV array is strongly dependent on operating conditions. Manufacturing cost of solar power is still high as compared to conventional power. Abstract
A solar photovoltaic, wind turbine and fuel cell hybrid generation system is able to supply continuous power to load. In this system, the fuel cell is used to suppress fluctuations of the photovoltaic and wind turbine output power. The photovoltaic and wind turbines are controlled to track the maximum power point at all operating conditions.
Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been underway since very beginning for the development of an affordable, in-exhaustive and clean solar energy technology for longer term benefits.
Another problem of solar systems is less voltage production which is improved by introducing a wide voltage gain-boost converter circuit. The features of this converter circuit are less development cost because it does not require more power electronics switches.
A PV HVDC grid connected system realizes PV power collection and voltage step-up through DC/DC converter of PV generation unit, making the output voltage directly reach the appropriate transmission voltage level. The typical structure of a HVDC collection and grid-connection PV power plant system is shown in Figure 2.
Here, one cell unit produces 0.85 V which is a negligible production source. The present PV energy supply networks are designed by integrating the multiple number of sunlight cells to enhance their energy production capability. The series cells integration provides the high current rating of the PV system.
