Risk-constrained optimal power flow with probabilistic guarantees [PDF]

open access: yes2014 Power Systems Computation Conference, 2014
Higher penetration of renewable energy and market liberalization increase both the need for transmission capacity and the uncertainty in power system operation. New methods for power system operational planning are needed to allow for efficient use of the grid, while maintaining security and robustness against disturbances.

Comparison of solving probabilistic optimal power flow methods in the presence of wind and solar sources

open access: yesMehran University Research Journal of Engineering and Technology, 2022
Power system control and operation studies have been experienced essential changes due to increasing the penetration of uncertain renewable energy resources. One of the most critical issues in this regard is the optimal power flow (OPF). As a result, the

Loss Reduction in Distribution Networks With DG Units by Correlating Taguchi Method and Genetic Algorithm [PDF]

open access: yesIranian Journal of Electrical and Electronic Engineering, 2022
Optimal power flow is an essential tool in the study of power systems. Distributed generation sources increase network uncertainties due to their random behavior, so the optimal power flow is no longer responsive and the probabilistic optimal power flow ...

Probabilistic Optimal Power Flow Analysis with Undetermined Loads [PDF]

open access: yesJournal of International Council on Electrical Engineering, 2012
AbstractThe load in power system usually can be fluctuated, sometimes awfully, due to sudden disturbance, measuring and forecasting error, or even its inherent nature. Therefore, the conventional deterministic generation dispatch problems are not enough to operate power system.

Probabilistically Robust AC Optimal Power Flow

open access: yesIEEE Transactions on Control of Network Systems, 2019
The increasing penetration of renewable energy resources, paired with the fact that load can vary significantly, introduce a high degree of uncertainty in the behavior of modern power grids. Given that classical dispatch solutions are "rigid," their performance in such an uncertain environment is in general far from optimal.

Analyzing probabilistic optimal power flow problem by cubature rules

open access: yesTurkish Journal of Electrical Engineering and Computer Sciences, 2022
This paper is devoted to revealing some properties of the probabilistic optimal power flow (POPF) problem. In conjunction with Hermite polynomial model, Nataf transformation is introduced to map POPF problem to the independent standard normal space. Firstly, a multivariate polynomial model is employed to represent the function relationship between POPF
