Study on Optimization Operation of Micro-energy Network Considering Electro-ammonia Conversion

Micro energy networks are an important way to achieve the “carbon neutrality” goal. To further explore the potential of energy conversion in reducing carbon emissions, this article proposes an optimized operation model for micro energy networks with refined power-to-ammonia conversion. Based on the operation model considering carbon trading and comprehensive demand response, an optimization model for micro energy networks with refined power-to-ammonia conversion is established, with the objective of minimizing the system’s operating cost and carbon emissions. Utilizing examples, various micro-source energy dispatch conditions are analyzed and the carbon emission costs, as well as the overall operating costs of the micro energy network, are calculated. The results show that compared with power-to-hydrogen conversion, using power-to-ammonia conversion in micro energy networks can effectively reduce system carbon emissions, with a decrease of 7.88% and a total operating cost reduction of 5.36%. This verifies the feasibility of the model and demonstrates that improving energy utilization can achieve the synergistic operation of the system’s economy and low-carbon emissions.
