| Solar power is a great potential of renewable energy to replace fossil fuel in the future. In recent years, new installed solar energy accounts for a very large proportion of the total renewable energy supplied to the load. However, the state of connecting large solar farms will affect the national power system stability and voltage quality in the local power system. Therefore, assessing impacts of solar farms on the power system is necessary to determine voltage stability, the limited capacity of solar power at each power system and the reliability of the power grid before and after solar power is installed. This study uses ETAP software to evaluate impacts of planned solar farms on the local power system in Hau Giang province in 2025. The simulation results show that the power system is stable in terms of power flow after solar farms operation, in which the system loss is significantly reduced. The voltages of the power system are not disturbed when the solar farms are available according to results of transient stability analysis. Power system reliability improves significantly after operating solar farms for specific loads. It is shown that SAIDI, SAIFI and CAIDI before and after solar farms are installed are 5,8524 and 4,9847 hours/customer/year respectively, 0,4134 and 0,3955 times/customer/year respectively and 14,157 and 12,602 hours/customer respectively. The results show that when 07 solar farms with total capacity of 265MW are put into operation, the solar farms have a positive impact on the power grid of Hau Giang province. | ||
