Abstract
Power-to-X (P2X) technology is the cornerstone of the transition from fossil fuels to green fuels. The current study investigates the day-ahead scheduling of a Green-Energy Industrial Microgrid (GEIM) to optimally participate in the energy market. The GEIM has to provide the synthetic production demands of ammonia and hydrocarbons to be used in the refinery applications. Furthermore, the GEIM incorporates two types of Electric Vehicle Charge Station (EVCS) and Green Methanol Filling Station (GMFS) to give fuel services for the respective vehicles by electricity and green Methanol. Moreover, the GEIM benefits from a combined heat and power (CHP) to serve a part of its electricity and heat demands, which is supplied through green Methane and hydrogen fuels. As the GEIM is subject to multiple uncertainties, a robust scheduling model is introduced for its cost-effective bidding to the energy market under handling the existing risks. The simulation outcomes indicate that to meet the synthetic fuel demands, it is necessary to produce 32.55 MWh of hydrogen through electrolysis. This quantity represents 77% of the total electric energy supplied by the GEIM over the operation day. Moreover, the operator's conservatism results in a 6.7% increase in market cost, a 7.6% rise in the amount of energy purchased, and a 10.5% increase in the volume of captured CO2.
