Abstract

This chapter assesses the reliability of a generation system (HL-I) using the Monte Carlo Non-Sequential (MCNS) simulation method and probabilistic indicators, as well as the static sense of a secured generation–transmission system (HL-II) on the basis of its voltage stability. For the purpose of mathematically modeling the system’s adequacy, two-state generator models are applied; and for the purpose of the load curve, a relative cumulative frequency histogram, with polynomial interpolation among classes, is used. The security assessment discussed herein is based on the continued load flow charts obtained using the Newton–Raphson method that can monitor the voltage system’s behavior to load increases. A modal analysis is also conducted in order to identify, from an overall perspective, the nodes that most contribute to loss of voltage stability in the system. Both assessments take into account the performance of the system stability limits. These limits are established on the basis of certain state variables, such as voltage range at each node, thermal limits on the transmission lines, and the reactive power limits of the generating units.
