| Abstract | The climate change problem raises more integration of variable renewable energy (VRE) sources such as wind and solar to power sectors. However, the intermittency of VRE sources not only induces various impacts to the power sector but also requires more power system flexibility. Therefore, this thesis intends to investigate the impacts of high VRE source penetration on power system operation and power plant operation. Moreover, the effects of Smart grid technologies demand response (DR) and plug-in electric vehicle (PEV) as power system flexibility measures are analyzed. The studied power system is Thailand's power system in the year 2037, the last year of the latest Thailand power development plan. Unit commitment economic dispatch (UCED) problem is formulated and solved by PLEXOS software every 30 minutes. In this study, the Smart grid allows end-users to participate in DR program by shifting their electricity consumption. Additionally, the innovation of PEV with smart charging capability can be either grid-to-vehicle (G2V) or vehicle-to-grid (V2G). The findings of the impacts of VRE sources show that higher VRE source penetration results in the reduction in electricity generation cost, CO2 emission and electricity price even though more VRE curtailment is also noticeable. VRE sources alter dispatch patterns by displacing expensive power plants and requiring frequent starting and ramping from other power plants. Moreover, they also cause power plants to generate electricity longer at the minimum power output level. DR can lower electricity generation cost, CO2 emission, VRE curtailment and electricity price during a peak period than without DR cases. Furthermore, they can reduce the utilization of expensive power plants and frequently relax, starting and ramping power plants. Additionally, DR is capable of decreasing power plant hours at a minimum. The advantages of PEV smart charging compared to uncontrolled PEV charging are also similar to the above described DR benefits both power system operation and power plant operation. |
