Generation Expansion Planning (GEP) is the problem of finding the optimal a highly constrained, non-linear optimization problem. GEP is the key step in long term planning issues when load is appropriately forecasted for a definite imminent period. Objective of this tutorial paper is to find the best possible combinations of plants that would meet the future demand. In this paper, two studies were carried out for GEP. In Study I, hypothetical 3 bus test system is considered with various cases via., Simple GEP without Constraints, Transmission constrained GEP(TC-GEP), Transmission constrained GEP including incorporation of Renewable Energy Sources RES, GEP with battery storage system and GEP considering emission characteristics. In Study II, Roy Billinton Test System (RBTS- 6 bus) is considered with different cases like, Simple GEP without constraints, TC-GEP with firm purchase, TC-GEP with simultaneous bilateral transactions, TC-GEP with multi-lateral transaction and TC-GEP with integration of all the above type of transactions that is firm purchase, simultaneous bilateral transactions, multi-lateral transaction, GEP with battery storage system and GEP considering emission characteristics. In both tutorial studies, simulations were also made using Power World Simulator for verifying line flow constraints. From the study results it can be inferred that GEP outcome is different for different type of constraints.
