Markov Decision Process-based Resilience Enhancement for Distribution Systems: An Approximate Dynamic Programming Approach
Chong Wang, Ping Ju, Shunbo Lei +2
Because failures in distribution systems caused by extreme weather events directly result in consumers' outages, this paper proposes a state-based decision-making model with the ob…
Mathematical representation of the WECC composite load model
Zixiao Ma, Zhaoyu Wang, Yishen Wang +2
The Western Electricity Coordinating Council (WECC) composite load model is a newly developed load model that has drawn great interest from the industry. To analyze its dynamic cha…
Secondary Voltage Control of Microgrids Using Nonlinear Multiple Models Adaptive Control
Zixiao Ma, Zhaoyu Wang, Yifei Guo +2
This paper proposes a novel model-free secondary voltage control (SVC) for microgrids using nonlinear multiple models adaptive control. The proposed method is comprised of two comp…
Counterexample to Equivalent Nodal Analysis for Voltage Stability Assessment
Bai Cui, Zhaoyu Wang
Existing literature claims that the L-index for voltage instability detection is inaccurate and proposes an improved index quantifying voltage stability through system equivalencin…
Optimizing Service Restoration in Distribution Systems with Uncertain Repair Time and Demand
Anmar Arif, Shanshan Ma, Zhaoyu Wang +3
This paper proposes a novel method to co-optimize distribution system operation and repair crew routing for outage restoration after extreme weather events. A two-stage stochastic…
Dynamic Game-based Maintenance Scheduling of Integrated Electric and Natural Gas Grids with a Bilevel Approach
Chong Wang, Zhaoyu Wang, Yunhe Hou +1
This paper proposes a dynamic game-based maintenance scheduling mechanism for the asset owners of the natural gas grid and the power grid by using a bilevel approach. In the upper…
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…
