Steel plant upgrade and energy storage project plan

First, aggregate production planning and energy supply management in the steel industry are considered simultaneously. Second, reducing both production and energy costs while minimizing CO 2 emissions is considered to develop a more sustainable planning model.

Several studies have also been conducted on energy planning for the iron and steel industries. The importance of both fossil fuels scarcity and pollutant emissions have recently attracted more attention of the researchers.

A mathematical model was developed by Zhang et al., (2019) to optimize energy use with CO 2 emission reducing in an iron and steel plant. The results showed that applying the proposed model decreases the optimal total site energy consumption and CO 2 emissions.

To date, various optimization methods have been studied in the field of production planning and energy management in many sectors, including the iron and steel industry. In the literature, most researchers focus on production planning. There are other studies that model energy planning in these sectors.

The steel (and iron) industry is a pillar industry of many national economies and is essential to countries' economic growth. However, it is also a specific industry with high energy consumption and resource requirements (Meng et al., 2023). This industry is one of the main energy-intensive industries with high CO 2 emissions.

Also, the selected production planning time depends on several factors such as electricity, labor, and maintenance costs, and pending orders that need to be fulfilled. The onsite power plant produces electricity when the electricity production cost is lower than the price of electricity provided by the connected grid.
