Study on the differences of low carbon development models for energy and power supply in different types of enterprise parks

As the main entities of undertaking the intensive energy activities, the green and low-carbon development of the enterprise parks is one of the important means to achieve the "dual carbon" targets. Taking two different types of parks, an industrial park and a research and technology park, in Guangzhou as the research objects, using Homer software and taking the minimum total net present value as the objective function, this study carried out the capacity optimization for different scenarios in order to optimize the allocation and analysis of low-carbon energy and electricity development plans for the two different types of enterprise parks. The results showed that: (1) for enterprise parks, fully utilizing renewable energy and equipping energy storage systems could effectively improve the economic and low-carbon efficiency of the energy system, while making use of the excessive power with electricity to heat conversion technology did not have significant effect. (2) Due to the intensive nature of land use, the enterprise parks were unable to adopt renewable energy sources on a large scale, resulting in an increase of unit cost of power supply. Compared with the research and technology parks, the industrial parks still have potential to make further improvement in economic efficiency.
