To maximize the consumption of renewable energy on the source side and better meet the demand on the load side
a bi-level optimal scheduling strategy is proposed for the multi-use pathways of power-to-ammonia and the capacity allocation of hybrid energy storage systems. In the upper level
the adaptive particle swarm optimization (APSO) algorithm is used to determine the optimal storage capacities with the objective of minimizing operational costs. In the lower level
to enhance system flexibility
gas turbine units with flexible heat-to-power ratios and ammonia fuel cells are introduced to address the limitation of adjustable power-to-heat output. Additionally
to reduce power generation costs
time-of-use electricity and gas prices
a demand response mechanism
and a tiered carbon trading scheme are incorporated. The objective is to minimize total system operating cost
and the model is solved using the CPLEX solver. Finally
comparative analysis of different scenarios demonstrates the proposed method's effectiveness in reducing carbon emissions
