Electrical Effects of Wind Energy Generation on Power System in Area of the Central II Part, Lao People’s Democratic Republic
Keywords:
Wind power generation, Voltage stability, Renewable energyAbstract
Currently, the hydropower plants are the important energy resources in Lao People’s Democratic Republic (Lao. PDR). However, the hydropower plants may have some disadvantages of generation and capacity depending on the water volume during the rainy season; therefore, the government has promoted the utilization of other renewable energy resources to increase the power stability. One project is the construction of the wind farm for renewable energy source to supply energy in Central II part, Lao PDR. In this paper, the electrical effects of wind energy generation on the power system were analyzed for installation in an area of Central II part, Lao PDR. The DIgSILENT software based on load flow analysis with the installed capacity at 20, 40, 60, 80, 100 and 120 % of energy lacking demand was used for the analyzer. The results indicated the dependence of the power flow, voltage, power factor and power loss of the system on the different installed capacities. The total power generation and power loss in this area of 126.24 MW and 5, respectively. The increased wind power generation of 40 % of energy demand can cause increment of power supply of 215.56 MW and power loss of 6% of total power generation. However, it can be reduced the import energy of 77.17 MW.
