Description
Summary:•A piecewise-linear formulation of the emission function of a generating unit.•A two-stage UC model for electricity production under stochastic emission limits.•Comparing the cost and emission using this model with those of alternative models.•Analyzing the effect of stochastic emission limits on power system scheduling. In some highly populated areas of the planet, air quality is an issue. Since power plants in those areas significantly contribute to air pollution due to SO2 and NOx emissions, it is appropriate to operate such power plants enforcing admissible emission limits. Since emissions directly impact the air quality index, which is highly uncertain 24h in advance, admissible emission limits should be modeled as stochastic parameters.To represent the stochastic nature of such admissible emission limits, we propose a two-stage stochastic programming model for the commitment of power plants. The first stage represents the day-ahead scheduling, and the second stage represents the real-time power system operation under different weather and thus admissible emission limit conditions. We show the effect of stochastic emission limits on power system operations using a simple example and a 118-node case study.
