Abstract:
This thesis studies on voltage stability enhancement for 22 kV power distribution system in Chanthaburi province by installing distributed generators. The appropriate size and location of the distributed generators were calculated by using mathematical methods.
Chanthaburis 22 kV power system can be divided into 6 areas which are Muang district, Tha Mai district, Kaeng Hang Maew district, Soi dao, Khlung district and Laem Singh district. Power flow and power losses in each area were computed to estimate the optimal size and location of the generators by using particle swamp optimization methodology. The result shown that proposed installing generators could reduce the losses approximately 50% for each area and decrease losses in Chanthaburis 22 kV power system by 20%.
Moreover, this solution is not only able to cut down power losses in the system but also enhancing the voltage stability as well as increasing load capability.
