Reliability nodal pricing considering CO2 emissions in a multi objective function

Abstract

This paper proposes a pricing model based on reliability which considers CO2 emissions using a multi-objective optimization criterion. The model performs a reliability analysis for the order of up to N-2 contingencies, the nodal prices per contingency are grouped into two user classes to have prices that reflect reliability and CO2 emissions. The first prices for reliability are class A which considers contingencies of the order N-1 and class B which considers emissions of the order N-1 and N-2. The objective functions to be optimized in this research work are: 1) prices for reliability and 2) CO2 emissions for contingency, because they have a greater impact on the reliability of the transmission system. In this case the price for emissions is reflected to the end user according to the type of contingency you want to have. The methodology determines the ENNS and contingency emissions to obtain the expected values per class. The methodology proposed in this article was implemented to optimize reliability and CO2 emissions in the 24-node test system proposed by the IEEE achieving satisfactory results.
