Description

A dispatching method based on mobile integrated energy system

Technical areas:

The invention relates to the technical field of integrated cold, hot and electric energy, and specifically relates to a mobile integrated energy system and a dispatching method.

Background technique:

With the further development of social economy, energy consumption is also increasing, which has led to the continuous shortage of fossil and other non-renewable energy sources and aggravated environmental pollution problems. In order to further achieve the goal of continuous reduction of "double carbon", implement China Energy Internet's plan to achieve carbon emission reduction targets, optimize the construction and operation of integrated energy systems, and promote the continuous use of renewable energy, which can alleviate the further shortage of non-renewable energy and enable It has good environmental benefits. Therefore, multi-faceted research on integrated energy systems has gradually become a hot issue. The further improvement of the development of various new energy sources provides prerequisites for the further development of integrated energy systems, especially the increasing improvement of solar energy systems. The integrated energy system relies on the input of external energy stations to ensure its own stable supply of energy required by users. Existing research on the energy flow of integrated energy systems is generally limited to the supply of energy by a single load, and the energy distribution and dispatching method of joint supply is still Immature, and after the integrated energy construction location is fixed, it can generally only provide energy supply and distribution to nearby users, and long-distance energy supply brings a lot of inconvenience and increases operating costs, which is not conducive to the integrated energy system. long-distance energy dispatch and operation.

The importance of energy optimization dispatching methods for integrated energy systems is self-evident to users. For example, there was a large-scale blackout in the UK in 2019. The blackout originated in the central and eastern regions of England and the northeastern waters, eventually causing power outages in most parts of England and Wales. The reasons for the accident are: (1) Due to the failure of the wind power system of the system and the insufficient backup energy of the system, when the system connection was disturbed, the system was not able to make up for the missing power in time, resulting in the load removal of some users. ; (2) The energy distribution and dispatch method is not timely and cannot provide guarantee services in times of energy shortage, nor can other comprehensive energy systems be added in a timely manner to supply it. It is particularly important to strengthen the optimization of energy distribution and dispatching methods for integrated energy systems.

With the increasing development of integrated energy, the environment it is required to adapt to is becoming more and more demanding. Integrated energy systems generally can only rely on the inherent energy location to determine the address, and are not yet able to realize their own independent energy supply. This makes the establishment of integrated energy systems difficult. Regional limitations increase. The integrated energy system involves many inherent energy enterprises. It is very challenging to build an integrated energy system in the short term to meet the energy supply needs of enterprises and other enterprises. Moreover, building temporary integrated energy systems in multiple regions will generate huge economic costs, which is not conducive to certain economic benefits and hinders further development of integrated energy systems.
