Two-Stage Optimal Operation Management of a Microgrid Considering Electricity-Hydrogen Coupling Dynamic Characteristics

Abstract

The uncertainty and volatility of renewable energy generation lead to large amounts of abandoned electricity. The electricity-hydrogen coupling microgrid (EHCM) consists of the proton exchange membrane electrolytic cell (PEMEC), liquid organic hydrogen carrier (LOHC) hydrogen storage, proton exchange membrane fuel cell (PEMFC). The structure helps to increase the utilization of wind and photovoltaic power. The scheduling of an EHCM is very challenging. This paper proposes the optimal operation of a microgrid considering the uncertainty of wind speed, light, and the coupling of electricity and hydrogen. The electricity-hydrogen coupling model and hydrogen market model are constructed. The microgrid provides ancillary services to the grid while meeting hydrogen demand. The above model is solved using a two-stage optimization method with time scales of day-ahead and intra-day. Finally, taking the IEEE 33-node microgrid as an example, the effectiveness of the proposed model is verified. The results of the case show that the proposed method can obtain more benefits and reduce carbon emissions.

Smart Grid: Leading International Experience of Marketing and its Contribution to Sustainable and Environmental Development of Energy Economy

“…In contrast to Albogamy et al (2022), Almutairi et al (2022), Liu et al (2022), Saxena et al (2022), Zaidan et al (2022), it was found that Smart Grid mainly depends on government governance, which includes both infrastructure support, and regulation of the energy economy. The role of corporate governance is secondary.…”

“…The publications of Albogamy et al (2022), Almutairi et al (2022), Liu et al (2022), Saxena et al (2022), Zaidan et al (2022) suggest the functioning and development of Smart Grid based on corporate governance with a secondary role of the state. Smart Grid is interpreted as a high-tech innovation of energy companies.…”
