Traditionally, candidate lines for the transmission expansion planning are manually selected, which faces great challenges in terms of multi-regional planning and large penetration of renewable energy sources (RES). In this paper, an approach is proposed to select candidate set of transmission lines automatically. The utilization level of RES can be ensured by the created candidate set. Through the...
As the increasing integration of renewable energy sources (RES), the problem of transmission expansion planning (TEP) is facing more and more challenge from the uncertainties of loads and RES generations. In this paper, a two-stage mathematical model for the TEP problem is presented to minimize the sum of investment costs and generation costs. To ensure the utilization level of the RES generation,...
The Chinese government plans to establish ultra-high voltage (UHV) systems to transmit an additional 250 GW of electricity by 2020. The plan includes prioritizing the development of 60 GW of hydropower in the western part of China. To transport power from the west to the eastern and southern industrial centers in Shanghai and Guangdong, the government intends to utilize UHV 800 kV DC for bulk power...
