Although significant private investment is absorbed in different sectors of power systems, transmission sector is still suffering from appropriate private investment. This is because of the pricing policies of transmission services, tariffs, and especially for investment risks. Investment risks are due to the uncertain behaviour of power systems that discourage investors to invest in the transm...

Transmission network expansion planning (TNEP) is a basic part of power system planning that determines where, when and how many new transmission lines should be added to the network. Up till now, various methods have been presented to solve the static transmission network expansion planning (STNEP) problem. But in all of these methods, lines adequacy rate has not been considered at the end of ...

In terms of the transmission network development case selection, there are deferent emphases for the development department, power dispatching and other departments, and evaluation indexes and methods in case selection of transmission network development are deferent to take, as a result it is difficult for the developing, scheduling and other departments of grid to form an objective, comprehen...

Compared with static transmission network expansion planning (TNEP), multi-stage TNEP is more in line the actual situation, but modeling also complicated. This paper proposes a new method based on deep Q-network (DQN) algorithm, which can solve problem model. The main purpose of this research to provide grid planners simple and effective method, able flexibly adjust scheme without replanning. p...
