Fuzzy power flow solutions with reactive limits and multiple uncertainties
Electric Power Systems Research, 2005Importance of simultaneous modeling of diverse sources of non-statistical uncertainty in power system analysis and optimization is being increasingly realized. Keeping this in view, an attempt is made to obtain fuzzy power flow solution considering reactive power limit violations at voltage controlled buses, uncertainties in voltage-dependent load ...

An Optimal and Distributed Feedback Voltage Control Under Limited Reactive Power
2018 Power Systems Computation Conference (PSCC), 2018In this paper, we propose a distributed voltage control in power distribution networks through reactive power compensation. The proposed control can (i) operate in a distributed fashion where each bus makes its decision based on local voltage measurements and communication with neighbors, (ii) always satisfy the reactive power capacity constraint, (iii)

Hilbert space techniques for reactive power compensation with limited current bandwidth
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004The paper formulates and solves an optimization problem related to reactive power compensation with limited current bandwidth. The current bandwidth limitation is essential for all practical compensators that are built around switching power converters. We use the Hilbert space terminology stated in H. Lev-Ari and A.M. Stankovic (2003) to formulate and

Reactive Power Provision with Distributed Energy Resources: Limitations, Potentials and Losses
2019 IEEE Milan PowerTech, 2019Presently, reactive power is mainly provided by conventional power plants. As the utilization of these sources decreases, alternatives must be found. Generally, variable renewable energy power plants can be used to provide reactive power for the grid but the utilization possess several challenges.

Solution of interval reactive power optimization model through defining security limits
2018 International Conference on Power System Technology (POWERCON), 2018The model of reactive power optimization including interval uncertainty (RPOIU) is used to make a voltage control strategy for ensuring the interval state variables (including load voltages and reactive power generation) of the power grid within their safe operating limits, under interval active power generation and power load demand input data.

2017 12th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2017
Voltage stability is dominant in heavily loaded systems with large disturbances. This is typically the case in the deregulated environment wherein the transmission systems are operating under more stressed condition. This is due to increased transaction level associated with open access. Abnormal voltage instability has occurred in several countries in
