| Summary: | 碩士 === 國立中正大學 === 電機工程學系 === 86 === This thesis proposes a new method for long-term capacity
expansion planning of composite power systems. The proposed
method applies the techniques of MonteCarlo simulation, network
flow approach, and dynamic programming. It has the capability of
determining the timing, size, and location of additional
requiredin the studied system to accommodate the expected load
growth over the planningperiod. The proposed method uses the
Monte Carlo approach to Simulate the outages of generations and
transmission lines and the variation of bus loads. Through
application of the network flow approach, it is capable of
handling the economic dispatch and power flow evaluation. The
network flow approach selects a minimumincremental-cost path of
the topological graph transformed from source to sink.
Incremental cost of the genrators and transmission lines on the
path selected isthen re-evaluated. Similar procedures are
repeated until all bus loads have beensatisfied or no more
available paths can be found. The system capacity expansion
planning is accomplished by employing dynamicprogramming and the
network flow method. A scheme based on the economic
benefitcomparison for alternative selection is used to determine
the additonal capacityneeded for each stage of the planning
period.
