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 consider multiple randomness, and energy management needs to be further optimized space, and the problem of significant decrease in calculation speed caused by random optimization and rolling optimization also directly affects the practical performance of energy management
