Abstract
Total Transfer Capability (TTC) was defined to provide information for energy trading management and transmission system planning in a deregulated environment. Although TTC calculation has been well researched and conducted, a new method is still required to take into account the presence of generation from renewable energy sources. Among the renewable energy sources used nowadays, wind and solar energies have received the most attention. The increasingly widespread use of wind and solar power generation is expected to have an impact on the TTC due to the fluctuating output strongly depending on the wind speed and climate. This paper primarily investigates such impact on the system TTC. The uncertainty from wind and solar power generation outputs is integrated into the calculation by using the Monte Carlo simulation. Based on the risk concept, the TTC at risk is selected. The validity of the proposed method is illustrated through the numerical simulation conducted on the modified IEEE 30-bus test system.
