In this paper, we will consider a midterm offer demand equilibrium model for electricity. This kind of model can be used for investment opportunity studies, wherein new assets are valued against obtained marginal costs on a restricted set of uncertainty scenarios. In order to correctly value peak-load assets, realistic marginal costs are required and hence dynamic constraints have to be added to the problem formulation. Unfortunately due to the size of the considered problem, formulating individual constraints would lead to a huge intractable mixed integer optimization problem. We therefore propose a formulation for aggregated units, therefore strongly reducing the problem size. We also demonstrate the feasibility of this formulation on a real-sized problem in a European context. © 2011 IEEE.
