N2  - This thesis provides an assessment on voltage profiles of a distribution system in the presence of  high level of solar rooftop PV penetration. Each household solar rooftop PV power generation is  calculated  by  PVWATTs  online  calculation  tool. Average  load  profile  in  northern  part  of  Provincial Electricity Authority (PEA) of Thailand is selected for the simulation. Simulation  results indicate the  maximum allowable PV installation per  house in which  voltage level do  not exceed standard operating  limits . Finally,  optimal  voltage regulation strategy using particle  swarm  optimization  (PSO - Q(U) method )  is used to minimize the total inverter reactive power  injection  subject  to  power  balance  equation,  inverter  reactive  power  injection  limits,  and  voltage  limits  are  shown.  Test  results  on  the  19  buses  radial  system  indicate  that  the  total  inverter reactive power injection of PSO - Q(U) method is lower than the simple Q(U) method , leading to a higher real power output capability of solar PV inverter
