A new Approach for Transmission Network Expansion Planning using Modified Reliability Assessment and Cost-optimization Method

Transmission network expansion planning (TNEP) faces critical challenges to not only keep reliability criteria, but also effectively reduce huge investment cost. Recently, TNEP has been modeled by probabilistic method for the security and reliability criteria, including power market concepts as well. This paper presents a reliable and economic approach for solving TNEP problem through a simple method. This proposed method can be briefly estimated of state probability to select TNEP candidates, and can be chosen for optimal alternative by using simplified equation. To demonstrate the efficiency of the suggested methods, these methods are applied to modified-24 bus IEEE-RTS.
