Towards High-Efficiency Cascading Outage Simulation and Analysis in Power Systems: A Sequential Importance Sampling Approach
Jinpeng Guo, Feng Liu, Jianhui Wang +2
This paper addresses how to improve the computational efficiency and estimation reliability in cascading outage analysis. We first formulate a cascading outage as a Markov chain wi…
Distributed Optimal Gas-Power Flow Using Convex Optimization and ADMM
Cheng Wang, Wei Wei, Jianhui Wang +2
This paper proposes a convex optimization based distributed algorithm to solve multi-period optimal gas-power flow (OGPF) in coupled energy distribution systems. At the gas distrib…
Nonlinear Model Reduction in Power Systems by Balancing of Empirical Controllability and Observability Covariances
Junjian Qi, Jianhui Wang, Hui Liu +1
In this paper, nonlinear model reduction for power systems is performed by the balancing of empirical controllability and observability covariances that are calculated around the o…
Strategic Bidding and Equilibria in Coupled Gas and Electricity Markets
Cheng Wang, Wei Wei, Jianhui Wang +2
The wide adoption of gas fired units and power-to-gas technology brings remarkable interdependency between natural gas and electricity infrastructures. This paper studies the equil…
Comparing Kalman Filters and Observers for Power System Dynamic State Estimation with Model Uncertainty and Malicious Cyber Attacks
Junjian Qi, Ahmad F. Taha, Jianhui Wang
Kalman filters and observers are two main classes of dynamic state estimation (DSE) routines. Power system DSE has been implemented by various Kalman filters, such as the extended…
Estimating the Probability of Wind Ramping Events: A Data-driven Approach
Cheng Wang, Wei Wei, Jianhui Wang +1
This letter proposes a data-driven method for estimating the probability of wind ramping events without exploiting the exact probability distribution function (PDF) of wind power.…
