Optimal Energy Mix and Operation Cost in the Presence of Nuclear and Solar PV Generation

Abstract

This paper investigates electrical energy mix and operation cost in Bangladesh for sustainable development. Projecting tentative energy demand by the year of 2025, the aspect of economic load dispatch is discussed. Several ongoing Government projects and their contribution to meet future demand, along with renewable energy scenario are critically reviewed. The prospects of feasible renewable energy resources are considered. To fulfill the electrical energy demand, optimal energy mix has been proposed. Three plausible scenarios have been considered for the year 2018, 2021 and 2025 respectively. The west zone power grid comprises of generation stations and sub-stations are considered to carry out the load at different buses at a minimum cost. Linear programmed optimum power flow method has been used to evaluate the generating capacity, operation cost as well as the selling price of each generating stations for both off-peak and onpeak hour. The emission of CO2 is calculated by considering the emission of each fuel type used in different generating stations.
