Uncertainties in modern power systems
Data-driven robust stochastic optimization for power systems
In a modern power system, many decisions are "wait-and-see." The uncertain variables representing "wait-and-see" decisions depend on the portion of the real data that reveal itself before the moment when the decision is made. As one of the main uncertainties in power system, wind power is one of the "wait-and-see" decisions needed.
Why is uncertainty a problem in quantum physics?
The uncertainty relationships come out of the wave-like behavior of objects at the quantum scale, and the fact that it''s very difficult to precisely measure the physical position of a wave, even in classical cases.

Frequency control of power systems under uncertain
However, traditional frequency control studies did not consider the types of uncertainties in modern power systems and lacked corresponding analysis methods. To address these problems, studies in the field of system control generally focused on the control of variables based on state space models and control theory; this approach can account
What is uncertainty principle?
Uncertainty principle, statement that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory. The very concepts of exact position and exact velocity together have no meaning in nature. Werner Heisenberg first stated the principle in 1927.
Uncertainty handling techniques in power systems: A critical review
In modern power systems, the uncertainties mainly arise from random variations in input data, prediction errors, and network failures. In addition, the growth of intermittent REs exacerbates the uncertainties in a structured power system.
