An integrated hybrid solar/wind converter for telecom applications

The control structure is framed to achieve power balance in the system along with basic functionality such as operating renewable sources PV and wind at maximum power point and charging and discharging of energy storage based on power availability.

The key highlights of the proposed configuration are: i Less number of switches, ii Voltage boosting, voltage regulation of supercapacitor and power-sharing among battery and supercapacitor are inherent, iii Simple control structure with a reduced number of sensors. The detailed analysis, modeling, and design of the proposed configuration and control structure are presented along with MATLAB simulations and experimental validations.

Article :. The solar array tilt is easily adjustable to maximize solar energy output. The systems are mounted on galvanized steel structures or containerized engineered to withstand harsh environments and high wind loads. These fully-integrated, galvanized units use DC primary power to charge a 12, 24 or 48 VDC sealed battery bank while powering the DC load, or AC load with integral inverter option.

In a Hybrid configuration the Systems allows the use of dual sources, DC primary and AC engine genset secondary, where load size makes it impractical to power by PV alone,. Because the peak operating times for wind and solar systems occur at different times of the day and year, hybrid systems are more likely to produce power when you need it.

Many hybrid systems are stand-alone systems , which operate "off-grid" -- that is, not connected to an electricity distribution system. If the batteries run low, the engine generator can provide power and recharge the batteries. Adding an engine generator makes the system more complex, but modern electronic controllers can operate these systems automatically.

An engine generator can also reduce the size of the other components needed for the system.
