FAQS about Risks of the wind-solar complementary industry for communication base stations

Is the complementary operation of wind and photovoltaic power a good idea?

The complementary operation of wind, photovoltaic and hydropower systems has the potential to increase the integration of renewable energy sources into an existing grid. However, the high variability and forecast uncertainty of wind and photovoltaic power may pose potential risks to the grid and cascade reservoirs.

Why is spectrum sharing a problem in solar powered BS?

Spectrum sharing in solar powered BSs is motivated by the fact that for a given rate requirement and channel noise (e.g. in an AWGN channel), the transmit power may be reduced by increasing the bandwidth, and vice-versa. The problem of energy and spectrum sharing may also be considered jointly.

How does the range of base stations affect energy consumption?

This in turn changes the traffic load at the BSs and thus their rate of energy consumption. The problem of optimally controlling the range of the base stations in order to minimize the overall energy consumption, under constraints on the minimum received power at the MTs is NP-hard.

How do solar powered BSS share energy?

To share resources so that outages are minimized or the quality of service (QoS) of users is improved, solar powered BSs may share energy either directly through electrical cables, or indirectly through power-control/load-balancing/spectrum- sharing mechanisms .

How to evaluate the risk and benefit of complementary operation?

To evaluate the risk and benefit of the complementary operation, the first step is to simulate the operation of the HS.
