Wind-solar hybrid for outdoor communication base stations
The invention relates to a wind and solar hybrid generation system for a communication base station based on dual direct-current bus control, comprising photovoltaic arrays, a wind-power
A hybrid system may usually connected to electricity grid. However, these hybrid systems can also be employed in stand-alone mode (Mannah et al., 2018). As mentioned earlier, energy storage devices provide energy balance and energy when no other power supply option is available.
Dahono et al. (2009) proposed a hybrid system comprises of 4.8kWp solar PV and 2.5 kW wind turbine along with 750 AH battery and a DG set to power telecom tower with an average load of 36 kWh per day. They have suggested that system performed stable and more economical over conventional options.
Similarly, modalities of optimally using hybrid systems for powering telecom towers should also be identified. Since the past two decades, conventional power supply options including the grid, batteries, and diesel generators have dominated the telecom towers' electricity supply.
A variety of hybrid power supply systems installed by various telecom operators are examined. Solar PV alone, solar PV and wind, wind alone, and fuel cell-based systems are popular among the various combinations studied. All of these hybrid systems are typically powered by battery storage.
