Description

Information-physical-value three-stream fused information physical energy routing method
Technical Field
The invention relates to the field of energy Internet, and provides an information-physical-value three-stream fused information physical energy routing method for comprehensively managing and controlling multiple types of energy accessed on a large scale, which provides support for an energy system and an ecological system of multiple energy optimization complementation and supply-demand interaction open sharing under a market mechanism.
Background
Energy crisis and environmental pollution issues have led to widespread attention in the development of distributed renewable energy sources. The effective utilization mode of renewable energy sources is 'on-site collection, on-site storage and on-site use'. However, the intermittent and fluctuating nature of renewable energy sources does not adequately guarantee energy balance, resulting in wind and light curtailment. In order to ensure that the renewable energy source fully ensures spontaneous self-use, the renewable energy source needs to be interconnected with other energy sources or public power grids, so that the improvement of the multi-stage control management requirements of the traditional power grids in the process of 'production-transmission-storage-distribution-use' and the like is promoted. Meanwhile, with the gradual cancellation of renewable energy subsidies, low-price electric power comes, which further promotes the upgrade and transformation of novel technologies such as large-scale renewable energy consumption technology, internet of things technology and the like, so as to break through in operation, maintenance, management and transaction of an intelligent energy network and fully exert the pushing effect of a market mechanism on energy interconnection.
It is a constantly evolving process from traditional grids to smart grids and finally to the energy internet.

In recent years, with the vigorous development of micro-grids and incremental power distribution networks in China, the gradual opening of the power market and the automatic localization of partial areas have become an important trend. The existing energy router is mainly used for realizing energy transmission and management of renewable electric energy or other types of energy, so that the core of the energy router is still focused on the aspects of energy flow and information flow, and no energy transaction mechanism is considered, and therefore, the research on an information-physical-value three-stream integrated energy routing mechanism is necessary, because the market mechanism is an impetus for promoting energy interconnection to play a decisive role.
