Transfer learning based dynamic security assessment

Transient stability based dynamic security assessment indices

As power systems become increasingly stability constrained, the need for dynamic security assessment (DSA) becomes important. However, the resources and technology required to achieve on-line DSA at reasonable cost for utility companies are not easily come by. Therefore, an offline method is needed to examine and screen all likely contingencies to determine those that may lead to instability. S...

Transfer Learning based Dynamic Multiobjective Optimization Algorithms

One of the major distinguishing features of the dynamic multiobjective optimization problems (DMOPs) is the optimization objectives will change over time, thus tracking the varying Pareto-optimal front becomes a challenge. One of the promising solutions is reusing the “experiences” to construct a prediction model via statistical machine learning approaches. However most of the existing methods ...

Hybrid Simulation / Measurement - Based Framework for Online Dynamic Security Assessment

Security-Constrained Power System Transfer Capability Assessment

Till now, many transfer capability techniques are performed in a simplified manner, with limited consideration of security constraints. This is unacceptable as the risks for not evaluating security impacts are high. There have been doubts on whether current techniques could provide secure transfer capability assessment and thus introducing a new challenge. This paper presents an optimal power f...
