A Necessary Condition for Power Flow Insolvability in Power Distribution Systems with Distributed Generators
Zhaoyu Wang, Bai Cui, Jianhui Wang
This paper proposes a necessary condition for power flow insolvability in power distribution systems with distributed generators (DGs). We show that the proposed necessary conditio…
Clearing and Pricing for Coordinated Gas and Electricity Day-ahead Markets Considering Wind Power Uncertainty
Runze Chen, Jianhui Wang, Hongbin Sun
The natural gas and electricity systems are now becoming more and more strongly coupled. While gas-fired units (GFUs) are replacing the retired coal plants, the power systems are a…
An SQP Method Combined with Gradient Sampling for Small-Signal Stability Constrained OPF
Peijie Li, Junjian Qi, Jianhui Wang +3
Small-Signal Stability Constrained Optimal Power Flow (SSSC-OPF) can provide additional stability measures and control strategies to guarantee the system to be small-signal stable.…
EV Dispatch Control for Supplementary Frequency Regulation Considering the Expectation of EV Owners
Hui Liu, Junjian Qi, Jianhui Wang +3
Electric Vehicles (EVs) are promising to provide frequency regulation services due to their fast regulating characteristics. However, when EVs participate in Supplementary Frequenc…
Robust Defense Strategy for Gas-Electric Systems Against Malicious Attacks
Cheng Wang, Wei Wei, Jianhui Wang +4
This paper proposes a methodology to identify and protect vulnerable components of connected gas and electric infrastructures from malicious attacks, and to guarantee a resilient o…
Wind Power Providing Flexible Ramp Product
Runze Chen, Jianhui Wang, Audun Botterud +1
The deepening penetration of renewables in power systems has contributed to the increasing needs for generation scheduling flexibility. Specifically, for short-term operations, fle…
Robust Integration of High-level Dispatchable Renewables in Power System Operation
Hongxing Ye, Jianhui Wang, Zuyi Li
The increasing penetration of Renewable Energy Sources (RES) requires more Flexibility Resources (FR), generally thermal units and storages, must be kept in the system to accommoda…
Robust Risk-Constrained Unit Commitment with Large-scale Wind Generation: An Adjustable Uncertainty Set Approach
Cheng Wang, Feng Liu, Jianhui Wang +4
This paper addresses two vital issues which are barely discussed in the literature on robust unit commitment (RUC): 1) how much the potential operational loss could be if the reali…
Dynamic State Estimation for Multi-Machine Power System by Unscented Kalman Filter with Enhanced Numerical Stability
Junjian Qi, Kai Sun, Jianhui Wang +1
In this paper, in order to enhance the numerical stability of the unscented Kalman filter (UKF) used for power system dynamic state estimation, a new UKF with guaranteed positive s…
