Real-time microgrid economic dispatch based on model predictive control strategy

Journal of Modern Power Systems and Clean Energy, 2017
To deal with uncertainties of renewable energy, demand and price signals in real-time microgrid operation, this paper proposes a model predictive control strategy for microgrid economic dispatch, where hourly schedule is constantly optimized according to

Mixed-integer second-order cone programming for lower hedging of American contingent claims in incomplete markets [PDF]

, 2013
Cataloged from PDF version of article.We describe a challenging class of large mixed-integer second-order cone programming models which arise in computing the maximum price that a buyer is willing to disburse to acquire an American contingent claim in an

Multi-period Market Operation of Transmission-Distribution Systems Based on Heterogeneous Decomposition and Coordination

Energies, 2019
The integration of shiftable/curtailment distribution generators (DGs) along with quick-response storage has not only increased the transaction’s flexibility but also puzzled the bidding willingness of transmission-connected market players (TMPs ...

Conic approach to quantum graph parameters using linear optimization over the completely positive semidefinite cone [PDF]

, 2015
We investigate the completely positive semidefinite cone $\mathcal{CS}_+^n$, a new matrix cone consisting of all $n\times n$ matrices that admit a Gram representation by positive semidefinite matrices (of any size).

Exact duality in semidefinite programming based on elementary reformulations [PDF]

, 2015
In semidefinite programming (SDP), unlike in linear programming, Farkas' lemma may fail to prove infeasibility. Here we obtain an exact, short certificate of infeasibility in SDP by an elementary approach: we reformulate any semidefinite system of the ...
