This study investigates several optimization problems on power network investment planning problems. The first paper provides a detailed literature review for long-term strategic electricity expansion planning (EEP) problems. The reviewed studies clustered under four categories: Generation, Transmission and Natural Gas Pipeline Expansion Planning, and Integrated considering these three studies in a single problem. The second paper is about integrated electricity and natural gas network long-term investment planning problem. The developed model specifically incorporates electricity generation, transmission and natural gas pipeline network in a single problem. The integrated problem considers renewable energy penetration to the existing power network and the supply fluctuation of the renewable energy resources. The third study proposes a mathematical model that provides a unique multi-objective mathematical model for integrated electricity and natural gas problem that includes overall network cost, environmental impacts, fuel cost risk factor and amount of imported fuel as objectives. A two-stage solution approach developed to find the most preferred solution considering the four conflicting objectives. In the fourth study, a mathematical model developed to select the best technology for the electricity energy storage (EES) units by using data envelopment analysis (DEA). EES units can be used to overcome the fluctuation of power production in renewable energy resources. The proposed study provides decision makers (DM) to make an initial decision for the EES units instead of considering all available EES technologies. The goal in this dissertation is to provide DM’s in power network field better insights for both power network expansion planning problems and efficiency evaluations of EES units. Both of these problems can be applied to any network and EES technologies.
