Optimal Scheduling of an Islanded Multi-Energy Microgrid Considering Power-to-Gas and Carbon Capture Technologies

Nowadays, carbon capture and storage (CCS) is recognized as one of the most effective strategies to decrease CO2 emission. Besides, power-to-gas (P2G) technology as an emerging system by converting the power generated from renewable energy resources into natural gas plays a key role in integrating renewable energies into multi-energy microgrids (MEMGs). So far, few works incorporate CCS and P2G facilities with the fully distributed coordination of MEMGs. To fill this gap, this chapter proposes an optimization approach for an islanded MEMG considering CCS and P2G technologies. In the investigated system, five energy carriers of power, heat, hydrogen, gas, and CO2 are proposed, where suppliers contain micro turbine, combined heat and power, wind turbines, and photovoltaic. Furthermore, this system presents multi-energy storage system including battery energy storage, thermal energy storage, hydrogen energy storage, gas storage, and CO2 storage. The total operating cost of the MEMG is maximized over 24-hour scheduling. Analyzing the results verifies the performance of the presented model.
