4 Frequently Asked Questions about “Wind power photovoltaic power and hydropower generation - ID Solar Energy Systems”
Are hydropower and photovoltaic regulated?
Wind power and photovoltaic are non-regulated power sources, and hydropower is not obliged to cooperate with them for access to the power grid under hydropower-wind-photovoltaic separate operation (HWPSO). At the moment, cascade hydropower stations only need to follow fluctuations of the system load in the power generation.
How does integrating wind and PV power affect hydropower efficiency?
The decrease in hydropower efficiency caused by integrating wind and PV power means lower water resources utilization efficiency under the complementary operation, which implies the 'sacrifice' of hydropower for operating more frequently in the low-efficiency conditions.
How to calculate hydropower generation in hwpes?
The derived comprehensive K H curves under different ranges of total daily wind and PV power can be used for the calculation of hydropower generation in the daily operation of the HWPES. Afterward, the curtailed wind and PV power can be estimated by the piecewise power curtailment function.
How does intermittent wind and PV power affect hydro unit generation efficiency?
In the short-term operation, the complementary operation with intermittent wind and PV power leads to changes in the operating patterns of hydro units , which further impact the hydro unit generation efficiency (i.e., the conversion efficiency from water resources to electricity of a hydro unit).
