Advanced Optimization of CCHP Microgrids: Strategies for Enhanced Efficiency, Reliability, and Sustainability

The worldwide shift to net-zero greenhouse gas emissions requires novel energy technologies that harmonize environmental sustainability with economic viability.Combined Cooling, Heating, and Power (CCHP) microgrids represent a significant improvement, utilizing cogeneration to enhance fuel efficiency and minimize energy waste.This study examines the use of Renewable Natural Gas, solar photovoltaics (PV), and sophisticated cooling technologies, including absorption chillers, into CCHP microgrids to improve their efficiency.The research illustrates, using comprehensive modeling techniques and practical case studies, the capability of these systems to realize energy cost savings above 35%, CO2e emission reductions of up to 50%, and enhanced energy security through robust designs.Practical applications of mathematical formulations demonstrate their function in maximizing storage capacity, managing curtailment, enhancing system reliability, and reducing economic losses.Scenarios encompass renewable penetration rates above 150%, LCOE reductions to $0.05/kWh in hybrid systems, and the requirement for sufficient storage to control peak demand.The results highlight the scalability and adaptability of CCHP microgrids in various geographic and operational settings, facilitating a resilient and carbon-neutral energy future.
