Distributed energy supply system equipment configuration and operation optimization design method

Abstract

The invention discloses a distributed energy supply system equipment configuration and operation optimization design method, which comprises the following steps: S1: designing a multi-energy flow distributed energy supply system containing photovoltaic power generation, wind power generation, a hydrogen fuel battery and an electrothermal hydrogen energy storage device; S2: proposing an optimal design goal of equipment configuration and operation of the distributed energy supply system; S3: based on the optimal design goal proposed in the step S2, carrying out the optimal design of the equipment configuration and operation of the distributed energy supply system. The distributed energy supply system equipment configuration and operation optimization design method in the invention introducesthe hydrogen energy flow into the energy supply system, and carries out hydrogen generation by electrolysis of water on the excess electric power of wind, light and electricity and uses a hydrogen storage tank to store hydrogen, and uses a fuel cell to generate electricity for supplying electricity and heat for the load when the terminal is large in load demand; at the same time, comprehensive optimization is proposed to carry out on equipment configuration and operation of the system from four aspects of technical goals, economic goals, environmental goals and social benefit goals, so that the system can have optimal configuration and optimal operation mode.

Description

technical field [0001] The invention relates to a distributed energy supply system equipment configuration and operation optimization design method. Background technique [0002] Adjusting the energy structure, reducing the consumption and emission of fossil energy, vigorously developing and utilizing renewable energy, and improving the clean level of terminal energy consumption are important strategic needs in my country at present. my country is rich in renewable energy resources such as wind energy and solar energy, which are suitable for large-scale development and utilization. However, since the large-scale construction of photovoltaic and wind power generation has far exceeded the capacity of local consumption, and the construction of delivery channels is lagging behind, the situation of abandoning wind and solar is serious, resulting in a serious waste of resources. In view of this, a distributed energy supply system dominated by renewable energy such as wind and rai...

Problems solved by technology

[0005] (2) The planning and design of existing distributed systems have not been comprehensively considered from different aspects

The planning and design of existing distributed systems are mostly based on annual operating costs, CO 2 Emissions or the minimization of annual energy costs are used as objective functions, and the design objective is single and incomplete

[0006] It can be seen that for the distributed energy supply system with multi-energy flow of electricity, heat and hydrogen, there is no comprehensive consideration of technology, economy, environment and social benefits to optimize the configuration and operation of system equipment.
