Capacity withholding assessment in the presence of integrated generation and transmission maintenance scheduling

摘要

In oligopoly power markets, maintenance of equipments may be scheduled strategically for exercising capacity withholding. In this study, an approach for analysing the capacity withholding of generation companies (GenCos) considering integrated generation and transmission maintenance scheduling (IGTMS) is proposed. This approach is based on some indices, which compare different types of power markets to analyse the effect of IGTMS on the capacity withholding of GenCos. The indices provide valuable information about capacity withholding, nodal price distortion, wealth transfer and loss of social welfare. The complex interactions of IGTMS with the capacity withholding of GenCos are provided with assessing extensive numerical simulations on two IEEE test systems.
