The electric vehicle charging load bring serious problems to the operation of power system. In this paper, a coordinated electric vehicle charging strategy is proposed to settle problem of load unbalance in three-phase distribution system. By monitoring the real-time power flow via the current sensor in each phase, the charging power is adjusted to implement the coordinated charging. Numerical results...
This paper presents an investment funds allocation model for distribution system upgrade based on data-driven technique. First, a bilevel programming evaluation system is established, which takes upgrade measures as element layer indices and comprehensive evaluation parameters as performance layer indices. In order to mine the correlation between these indices, enormous indices data generated by a...
Assessing security margin of operation is vital in situation awareness for power systems with centralized wind farm integration. Total transfer capability (TTC) can be used as an indicator referring to the maximal loadability of transmission corridors. However, the calculation of TTC considering wind generation is a computation-intensive procedure. In order to assess TTC, an estimation approach based...
In order to achieve online awareness of the transient stability of power systems, 10 different transient indicators that can be directly obtained or indirectly calculated using WAMS measurement data were chosen as original covariates for regression analysis of stability margins. Furthermore, feature covariates were consequently selected via a method called Nonparametric Independence Screening (NIS)...
