Predictive Prescription of Unit Commitment Decisions Under Net Load Uncertainty
Ogun Yurdakul, Feng Qiu, Sahin Albayrak
To take unit commitment (UC) decisions under uncertain net load, most studies utilize a stochastic UC (SUC) model that adopts a one-size-fits-all representation of uncertainty. Dis…
Adaptive Stochastic Optimisation of Nonconvex Composite Objectives
Weijia Shao, Fikret Sivrikaya, Sahin Albayrak
In this paper, we propose and analyse a family of generalised stochastic composite mirror descent algorithms. With adaptive step sizes, the proposed algorithms converge without req…
Adaptive Zeroth-Order Optimisation of Nonconvex Composite Objectives
Weijia Shao, Sahin Albayrak
In this paper, we propose and analyze algorithms for zeroth-order optimization of non-convex composite objectives, focusing on reducing the complexity dependence on dimensionality.…
Optimistic Optimisation of Composite Objective with Exponentiated Update
Weijia Shao, Fikret Sivrikaya, Sahin Albayrak
This paper proposes a new family of algorithms for the online optimisation of composite objectives. The algorithms can be interpreted as the combination of the exponentiated gradie…
Quantification of the Impact of GHG Emissions on Unit Commitment in Microgrids
Ogun Yurdakul, Fikret Sivrikaya, Sahin Albayrak
The global climate change creates a dire need to mitigate greenhouse gas (GHG) emissions from thermal generation resources (TGRs). While microgrids are instrumental in enabling the…
Kullback-Leibler Divergence-Based Distributionally Robust Unit Commitment Under Net Load Uncertainty
Ogun Yurdakul, Fikret Sivrikaya, Sahin Albayrak
The deepening penetration of renewable resources into power systems entails great difficulties that have not been surmounted satisfactorily. An issue that merits special attention…
A Distributionally Robust Optimization Approach for Unit Commitment in Microgrids
Ogun Yurdakul, Fikret Sivrikaya, Sahin Albayrak
This paper proposes a distributionally robust unit commitment approach for microgrids under net load and electricity market price uncertainty. The key thrust of the proposed approa…
