| Summary: | 碩士 === 明新科技大學 === 電機工程研究所 === 95 === As wind power penetrations increase in isolated power systems, more innovative and sophisticated approaches to system operation will need to be adopted due to the intermittency and unpredictability of wind power generation. Wind power penetration in Taiwan power system faces significant barriers due to limited transmission capability. One of the most important future challenges seems to be the management of the integration of fluctuations in the electricity production from wind energy sources. This development will cause a severe change in the demands on the power reserve due to the high fluctuations and the limited predictability of wind power generation. To assess the impact and economic benefits of the installation of wind farms, a particle swarm optimization with improved inertia weight (PSO-IIW) is developed in this dissertation to facilitate economic sharing of generation and reserve across areas, and minimize the total generation cost in the multi-area wind-thermal coordination dispatch problem. The PSO-IIW algorithm is to further modify the particle swarm optimization (PSO) to enhance its search capacity that leads to a higher probability of obtaining the global optimal solution. The effects of tie-line congestion and area spinning reserve requirement are consistently reflected in the total production cost. Several technique constraints are applied to determine the optimal proportion of wind generator capacity that can be integrated into the multi-area isolated system. Numerical experiments are included to understand the effects of wind generator capacity in production cost analysis and to illustrate the impacts of transmission capacity limits on wind power penetration level in each area.
