摘要：The technological development and the decline of PV investment have resulted in therapid growth of PV power plant. However, the power generated from the PV power plant cannot be controlled because it depends on the natural state of the sun. Therefore PV only suppliespower during the day. Consequently, the demand load supplied by the thermal generator becomessmaller during the day with greater PV penetration. When the penetration is too large, there is apossibility of a thermal generator scheduling failure. This paper presents a study of thepermissible photovoltaic (PV) power penetration related to generation scheduling by consideringsystem and generator units constraints. The unit commitment problem is solved using MixedInteger Quadratic Programming (MIQP). PV power plants with various sizes are put into thesystem until the algorithm fails to find a unit commitment solution. The infeasible solution ofunit commitment problem occurred at PV penetration 69% due to the load ramping needed bythe system at certain hours is higher than the maximum ramping capability of the thermalgenerator unit.
