| Summary: | Transmission network expansion planning (TNEP) is a classic issue in power system studies that has been studied many times. Aim of TNEP is providing enough capacity to transfer power from generation section to load centers in a reliable and economically efficient manner. The mission of this problem is identifying where, when and what type of new transmission lines should be installed in transmission network.Purpose of this article is comparing the IGDT, TOAT and STC methods in robust TNEP (RTNEP) in the presence of load and wind power generation uncertainties. Using these methods, robust expansion plans for the modified 6-bus Garver test system are determined and compared. The simulations results confirm validity of these methods in RTNEP. Therefore, these methods can be easily implemented on any large and real scale power system. Moreover, different types of uncertainties can be easily considered in this planning. Simulation results show, the IGDT method has more computational burden, which considering that the RTNEP problem is a long-term problem, the CPU running time and computational burden are not important. Therefore, the IGDT method is preferable to the TOAT and STC methods due to the ability to find the optimal expansion plans with less investment cost.. |
