碩士 / 國立臺灣科技大學 / 電機工程系 / 107 / In order to cope with the development of the renewable energy policy in the Republic of China in recent years and promote energy transformation, the power generations of firepower and nuclear power and other traditional units are reduced to increase the amount of renewable energy generation. Among them, the construction of offshore wind power has gradually matured and become the development focus of renewable energy in various countries. This thesis uses the PSS/E simulation software to simulate the locations with the potential of the offshore wind farms. With reference to the current policy plan, The offshore of Taoyuan, Miaoli, Changhua and Yunlin is selected as locations for offshore wind farms. The D/S substations of the seas are set to be the joint of the offshore wind farms. The 161kV buses are selected in the areas are connected to the network in a centralized, average decentralized and the line carrying rate manners. First, the maximum grid-connectable capacity of the system without adding additional lines and adopting the N-1 accident criteria is found, and it compare with the planning goals of Taipower in 2025. The simulation results show that if the transmission lines are not added, the regional congestion of transmission lines will happen, and the amount of the offshore wind farms connected to the grid will be limited. Therefore, it is unable to meet the government's goal of setting 5.5GW of offshore wind farms in 2025. In the second half of the thesis, the Changhua area was used as a simulation object. The three ways to find additional transmission lines were found to find the optimum point for the transmission line to solve the problem of regional transmission congestion and increase the grid connection. The final simulation results show that the addition of three transmission lines can meet the government's planning goals and improve the congestion of the line. Finally, the benefits, advantages and disadvantages of the three search methods are compared. The results can also be used as a reference for system construction and improvement when offshore wind farm planning is incorporated into Taiwan's power system.
Keywords: large offshore wind farms, steady state stability analysis, Power System Simulator for Engineering (PSS/E), new added transmission lines.
