A novel DRO model for self-scheduling problem
What about this project/study?
This study proposes a novel moment-based distributionally robust optimization (DRO) model with
conditional value-at-risk (CVaR) for self-scheduling problem under elecyticity price uncertainty.
This model comprehensively considers electricity price fluctuations, unit parameters and load re-
quirement, and it can be adjusted by adjusting the size of the ambiguity set, so it provides a
suitable and adjustable self-scheduling strategy for generation companies (GENCOs), decision makers
can adjust the strategy according to the actual scenarios for the scheme to be accepted by independents
system operators (ISOs) while maxmizing the generation profit. Such DRO models are usually translated
into semi-definite pro-gramming (SDP) for solution, however, solving large-scale SDP needs a lot of com-
putational time and resources. For this short-coming, two effective approximate models are proposed:
one ap-proximate model based on vector splitting and another based on alternate direction multiplier me-
thod (ADMM) algorithm, both can greatly reduce the calculation time and resources. In order to verify the
correctness and effectiveness of our proposed model, we apply them on a various of numerical case studies,
and compare with the model in [1].Simulations of three IEEE test systems (6-bus system, 30-bus system and
118-bus system) are conducted.
