| Summary: | This dissertation describes the development of two hybrid methodologies for the reliability analysis of interconnected power systems. These hybrid techniques combine the ad vantages of the state space decomposition technique and Monte Carlo simulation to provide multi-area and composite system reliability analysis tools which allow improved system modeling by including DC load flow constraints. The first, the method of decomposition-simulation including DC flow constraints, uses simultaneous decomposition-simulation, and accommodates all generation contingencies and a limited number of tie-line contingencies. The second, the method of pruning and simulation, consists of pruning of the state space prior to simulation, and accepts all generation and tie-line contingencies. Both techniques can deal with arbitrary network configurations, and can treat arbitrary probability distributions of generation and transmission systems. The applicability of both methods to multiarea systems is tested using several multi-area configurations of the IEEE Reliability Test System, while the applicability of the second method to composite systems is tested by using a modified form of the IEEE-RTS. The efficacy of both methods is demonstrated by comparing their performance, in terms of speed as well as accuracy, with that of pure Monte Carlo simulation methods. The benefits and capability of both methods are described, and possibilities of extending and enhancing them are suggested. |
