Implementation of the pumped-storage unit on static transmission network expansion planning problem considering emission

This paper presents the impact of the pumped-storage (PS) unit on the static transmission network expansion planning problem (STNEP). The aim of this work is to minimize the total cost and emission produced by the CO₂. The total cost is the summation of the transmission line cost and the fuel cost of the generating units. In growing power industry the generation sources are the main equipment, as there are various types of the generating sources. Their selections are done to achieve a more eco-friendly and economical. Hence, the impact of emissions on the STNEP needs to be analyzed. The proposed problem is tested on the IEEE 24-bus system and the gbest-guided artificial bee colony (GABC) optimization algorithm is applied to this problem. The results obtained indicate that the PS unit is effective to reduce the total cost and CO₂ emission level.
