| Abstract | This thesis studies the impact assessments on the technical side of the An Phong wind project when connected to the national power system, and analyze the feasibility of the project financially. For technical effects, by using the PSS/E and PSAT simulations, the results obtained will evaluate the change in voltage, power flow on the branches, losses and small signal stability of the regional power system when the wind generation is connected to the modified 18-bus 110/220kV Vietnamese system. Due to the fact that the wind farm absorbs reactive power from the system when producing active power, all voltage profiles surrounding buses of An Phong wind farm decrease slightly, but these voltages are within acceptable limits, and the total system loss also increases accordingly. On the other hand, the power transmitted from the 220kV national system to supply the local loads through the two 220kV substations is reduced, ensuring the system generation can meet the load demand if either 220kV substation is outage. In addition, from the results of small signal stability analysis by eigenvalue technique, the system will have damped oscillations and get stable if having a small disturbance. For financial analysis, through the study of the preferential policies of the government of Vietnam for wind power projects, the determination of the financial targets of the project such as IRR, NPV, B/C ratio and payback period are indicators for investors to determine the feasibility of the project. The IRR, NPV and B/C ratio indicators are acceptable to invest, whereas the payback period is quite long (16 years). And therefore, the recommendations have been given such as the proposals about the preferential policies, especially for the selling price of the electricity so that the financial norms would be preferable by which the wind project becomes more attractive to the investors. |
