A security-constrained energy and spinning reserve markets clearing system using an interior-point method

A model and solution approach to a daily energy and spinning-reserve electricity markets clearing system is presented in this paper. The model considers offers for energy supply and spinning reserve, bids for demand of energy and re-schedulable bilateral contracts. System security is taken into account by using a direct-current model. The model represents the clearing system used by an ISO in charge of both the market and system security, The clearing system is formulated as an optimization problem which is solved using an interior-point method (IPM), taking advantage of the problem's special structure.
