The optimal scheduling method of hydrogen integrated energy system considering carbon emission cost

Abstract

As a kind of clean secondary energy, hydrogen can promote the consumption of renewable energy. Considering the access to hydrogen energy, the operation mode of the integrated energy system is more flexible, which can improve the utilization efficiency of clean energy, effectively reduce carbon emissions, and reduce the impact on the environment. However, in the existing research, the carbon emission cost of the operation of the integrated energy system has not been considered, and it is difficult to fully reflect the environmental protection benefits of the integrated energy. To this end, a steeped carbon emission cost mechanism is constructed, and then an optimal scheduling method for the integrated energy system containing hydrogen is proposed. Firstly, a stepped carbon emission cost mechanism is constructed considering the carbon emissions from the operation of the integrated energy system. Secondly, the optimal operation model aiming at the lowest carbon emission cost and energy purchase cost of the integrated energy system is established. Finally, the calculation example shows that considering the cost of carbon emission can effectively promote the local consumption of renewable energy, reduce the carbon emission of the operation of the integrated energy system, and take into account the economic and environmental benefits of the operation of the integrated energy system.
