Energy management method applicable to multi-energy cooperation comprehensive energy network in Internet of energy

Abstract

The invention discloses an energy management method applicable to a multi-energy cooperation comprehensive energy network in the Internet of energy. The uncertainties of forecast variables such as an output of renewable energy power generation equipment, a requirement on an electric and thermal load and real-time fluctuation of the energy market price are expressed by a scene generation technology according to constraint conditions such as multi-energy stream energy balance and equipment operation of the applied multi-energy cooperation comprehensive energy network in the Internet of energy, a random planning model with the lowest total energy cost for operation and full power generation with the output of a distributed power supply is constructed, and rolling optimization is realized by applying the model forecasting and control principle; and a management strategy is solved by a two-layer accelerated solving structure including an input layer and a solving layer so as to ensure that energy management has the capacity of quick and on-line solving.

Description

technical field [0001] The invention relates to the field of energy management, in particular to an energy management method suitable for a multi-energy collaborative integrated energy network in the energy internet. Background technique [0002] With the increasing demand for supply-side structural reform in the energy field, the Energy Internet will improve the efficiency of comprehensive energy utilization, reduce energy costs, and promote the consumption of renewable energy by building a multi-energy collaborative comprehensive energy network that includes information and communication infrastructure. The development of distributed energy equipment, energy storage equipment, related prediction models, demand response and other technologies also provides a broader prospect for multi-energy collaborative integrated energy network and its energy management. At present, the corresponding energy management technologies are mostly concentrated in systems with a single energy t...

AI Technical Summary

Problems solved by technology

At present, the corresponding energy management technologies are mostly concentrated in systems of a single energy type, and there is less energy management for multi-energy collaborative networks; and the related energy management methods have a single time scale, or do not
