Optimal design of multi-generation system with solid oxide fuel cell, gas turbine and gas engine

The integrated solar energy hybrid system employs decentralized, energy-efficient strategies across various energy production methods, offering advantages such as enhanced efficiency, reduced emissions, cost-effectiveness, sustainability, and reliability. This study presents the optimal design of a solar-fossil-fuel-based system for combined cooling, heating, power, and freshwater production. The prime movers for simultaneous power and heat generation include gas engine, gas turbine, and solid oxide fuel cell. The proposed system configuration comprises a prime mover, two chillers, an auxiliary boiler, a desalination unit, parabolic trough collectors, a proton exchange membrane electrolyzer, and thermal and cooling storage tanks. The genetic algorithm is employed as the optimization method to minimize the total annual cost. The optimal outcomes disclosed that the exergy efficiency of the CCHPW system with GE is approximately ۴۰.۳۱% and ۹۲.۵۰% higher than that of the SOFC and GT systems, respectively. The optimal CCHPW system with GE achieved a ۲۷.۰۸% and ۲۳.۸۰% reduction in TAC compared to systems with SOFC and GT, respectively.
