Development of a Forward/Backward Power Flow Algorithm in Distribution Systems Based on Probabilistic Technique Using Normal Distribution

Advances in Electrical and Electronic Engineering, 2014
There are always some uncertainties in prediction and estimation of distribution systems loads. These uncertainties impose some undesirable impacts and deviations on power flow of the system which may cause reduction in accuracy of the results obtained ...

Probabilistically Robust AC Optimal Power Flow

IEEE 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.

A probabilistic resilience assessment method for distribution system operation with probabilistic optimal power flow

Energy Reports, 2022
The modern power distribution systems are vulnerable to natural disasters and malicious attacks, while the uncertainty of a large amount of renewable energy sources (RESs) further increases their operational risk in extreme events.

A probabilistic power flow calculation method considering the uncertainty of the static frequency characteristic

Global Energy Interconnection, 2019
In a power system, power generation and load have frequency response characteristics, which randomly fluctuate with changes in operating status. This study investigates a probabilistic power flow method that considers the unit and load uncertainty of the

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

Mehran 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
