Before revision:  The aim of this paper is to present a  heuristic-free , exact and computationally tractable model, which solves the market clearing problem in the presence of both curtailable block orders and the UPP.
After revision:  The aim of this paper is to present a non-iterative and heuristic-free , exact and computationally tractable model, which solves the market clearing problem in the presence of both curtailable block orders and the UPP.
