Techno-economic dispatch model to combine pumped hydro with solar, wind power
A research team in Spain has developed an hourly mathematical model that reportedly allows for the optimal management of grid-connected renewable generation facilities and pumped hydro-energy storage with reversible pump turbine. The scientists tested the model on a potential pumped hydro-solar-wind complex in northern Spain and found that the combination of the three technologies may achieve considerable savings.
The weekend read: Bigger modules yes, but better…?
It is now a well-established trend. After the switch to larger wafer sizes played out in 2019, this year has seen virtually all of the biggest PV manufacturers introduce new modules in dimensions above the 2-meter mark, and with power ratings in excess of 500 W – in some cases, as high as 800 W. As these modules begin to roll off production lines in larger quantities, it’s vital to take a look at the challenges and opportunities they bring to system design, installation, and long-term operation.
