Zhaojian Wang, Feng Liu, John Z. F. Pang +2
This paper addresses the distributed optimal frequency control of power systems considering a network-preserving model with nonlinear power flows and excitation voltage dynamics. S…
Optimal Power Flow in Stand-alone DC Microgrids
Jia Li, Feng Liu, Zhaojian Wang +2
Direct-current microgrids (DC-MGs) can operate in either grid-connected or stand-alone mode. In particular, stand-alone DC-MG has many distinct applications. However, the optimal p…
An Adjustable Chance-Constrained Approach for Flexible Ramping Capacity Allocation
Zhiwen Wang, Chen Shen, Feng Liu +2
With the fast growth of wind power penetration, power systems need additional flexibility to cope with wind power ramping. Several electricity markets have established requirements…
Breaking Diversity Restriction: Distributed Optimal Control of Stand-alone DC Microgrids
Zhaojian Wang, Feng Liu, Ying Chen +2
Stand-alone direct current (DC) microgrids may belong to different owners and adopt various control strategies. This brings great challenge to its optimal operation due to the diff…
Risk-limiting Load Restoration for Resilience Enhancement with Intermittent Energy Resources
