| Summary: | This study focused on the development and novel application of a new version of NARP (N-Area Reliability Program) to evaluate and search for an effective and economic way to maintain and improve power systems reliability under deregulated environment. A revised Monte Carlo simulation model (NARP-II) has been developed for accurate assessment of reliability of bulk power systems under deregulation. The revised simulation model incorporates a newly developed detailed transmission network model based on the use of the REI equivalent that permits accurate modeling of transmission networks while substantially reducing computational burden. The accuracy of using REI Equivalent in reliability study has been extensively tested and verified by using IEEE Reliability Test System. The use of the model and the potential impacts of deregulation on power systems reliability were illustrated using the Electric Reliability Council of Texas (ERCOT) system as it existed in 1998. For the study of the impact of a deregulated environment on power systems reliability, six different unit commitment policies or scenarios and two different transmission pricing methods have been modeled. Transmission price has been considered in the unit commitment for a better and more accurate system modeling under deregulation. Results show that the deregulation may have a significant adverse impact on the reliability (adequacy) of bulk power systems depending especially on the distribution of generating units and their commitment priorities over the system and the topology and capacity of the transmission network. A new transmission pricing method has been presented which reflects both owning and operating costs and the costs of unreliability. For the first time, the costs of reliability are directly considered on the same economic basis as other transmission costs. To further improve system reliability, an Expansion Fund has been introduced to provide more economic incentive for transmission system expansion. Case study shows that the combination of the unified transmission use charge and the Expansion Fund should provide economic signals encouraging both the proper use of the transmission system in the near term and the expansion of the network over time for the overall benefit of consumers. |
