“…The CHP plant proposed in this paper and Seo [59] is economically feasible as the NPV is greater than zero. The LCOE of the SBG-SOFC-GT-SPS CHP plant is USD 0.16/kWh, lower than that of the SOFC-GT CCHP plant proposed by Kumar [18] but higher than that of the SBG CHP plant [59], which is due to the fact that compared to the former, the system replenished biomass and solar energy, significantly reducing the annual fuel cost. However, compared to the latter, higher capital costs are required for the SOFC equipment.…”

“…where i and n represent the interest rate and the life of system, respectively. The LCOE is defined as the ratio of the overall costs evaluated during the entire project period to the total amount of electricity and heat generated in the same period [59]. The formula for the LCOE can be written as follows:…”

Renewable energy integration is a crucial approach for achieving a low-carbon energy supply in industrial utility systems. However, the uncertainty of user demand often leads to a mismatch between the system’s real operating conditions and the optimal operating points, resulting in energy wastage and high emissions. This study presents a multi-source heat and power system that integrates biomass gasification, solar collecting, solid oxide fuel cell (SOFC), gas turbine, and steam power systems. A scheduling strategy that varies the heat-to-power ratio is proposed to accommodate changes in user requirements. A simulation model of this multi-source system is established and validated. The influence of three key parameters on system performance under different configurations is explored. Energy and economic evaluations are conducted for three different configurations, and the system’s energy production and adjustable range are determined. The analysis reveals that, under the optimal configuration, the system can achieve an energy efficiency of 64.51%, and it is economically feasible with the levelized cost of electricity (LCOE) of USD 0.16/kWh. The system is capable of producing an output power ranging from 11.52 to 355.53 MW by implementing different configuration strategies. The heat-to-power ratio can be adjusted from 0.91 to 28.09.
