The fields of power system engineering and operations research are growing rapidly and
becoming increasingly entwined. This survey aims to strengthen the connections between …

Abstract Purpose of Review Competitive electricity systems arose in the context of thermal
generation with dispatchable production and increasing variable costs. This paper …

We provide a comprehensive overview of mixed-integer programming formulations for the
unit commitment (UC) problem. UC formulations have been an especially active area of …

This paper summarizes the technical activities of the IEEE Task Force on Solving Large
Scale Optimization Problems in Electricity Market and Power System Applications. This Task …

In power system studies the unit commitment problem (UC) is solved to support market
decisions and assess system adequacy. Simplifications are made to solve the UC faster, but …

This article analyzes how the Unit Commitment Problem (UCP) complexity evolves with
respect to the number n of units and T of time periods. A classical reduction from the …

The presence of non-convexities in electricity markets has been an active research area for
about two decades. The—inevitable under current marginal cost pricing—problem of …

Unit Commitment is usually formulated as a Mixed Binary Linear Programming (MBLP)
problem. When considering a large number of units, state-of-the-art methods such as branch …

Near-optimal unit commitment (UC) scheduling is a practical reality in wholesale electricity
markets. This paper revisits previous work that has found that minor differences in cost …

We present a novel formulation for startup cost computation in the unit commitment problem
(UC). Both our proposed formulation and existing formulations in the literature are placed in …
