Multi objective optimization and multi criterion decision making in expanding existing standalone energy systems combing renewable energy sources

Abstract

Hybrid Energy Systems (HESs) are becoming popular for standalone applications due to price volatility of fossil fuel resources and global concern on GHG emission. Expansion of an existing standalone Internal Combustion Generator (ICG) system while incorporating renewable energy sources is taken in to discussion in this work which converts ICG systems into a HES. In order to achieve this, a standalone HES consisting of wind turbines, Spy panels, batter bank, ICG and bi-directional converters is mathematically modeled, simulated and optimized considering power supply reliability, Levelized Energy Cost (LEC) and Renewable Energy Capacity (REC). Obtained Pareto fronts were analyzed and simple multi-criterion decision making technique is used to come up with the final system design.
