New algorithm may help mitigate unequal power curtailment
Developed by researchers in South Africa, the proposed technique is based on the water cycle algorithm (WCA), a population-based metaheuristic optimization algorithm that is inspired by the water cycle process in nature and how streams and rivers flow into the sea.
Chinese PV Industry Brief: NEA moves forward with curtailment plan
China’s National Energy Administration (NEA) says that utilization rates of solar and wind projects in specific provinces must not fall below 90%.
Texas curtailed 9% of solar generation in 2022
Transmission and energy storage limitations in Texas resulted in wasted renewable energy last year.
Curtailment is not the enemy
A new report by IEA-PVPS Task 16 looks at the use of “implicit storage” to transform intermittent renewable sources such as solar and wind into firm power generation. It shows that the total cost of the electricity system transformation could be lowered with the optimal use of capacity overbuilding and dynamic curtailment.
Grid constraints threaten to curtail more than 1 GW of solar projects in North Queensland
The northern Australian region this week added nine solar plants to the two already threatened – along with a wind farm – with having their output halted under certain conditions.
