Abstract

The invention relates to a regional energy internet multi-source coordinated optimization operation strategy considering time-of-use power price. The strategy is technically characterized by comprising the following steps that step 1, the initial data parameter of a regional energy internet system is inputted; step 2, cold / heat / electric flexible load response under the time-of-use power price is analyzed, and two classes of response models of cold / heat / electric flexible load are constructed; step 3, a regional energy internet system optimization scheduling model of the minimal economic cost and the operation constraint conditions thereof are constructed; and step 4, the regional energy internet system optimization scheduling model of the minimal economic cost is solved by using a Hessian interior point method. The regional energy internet renewable energy consumption level can be enhanced, and the strategy is also significant for realizing economic and safe operation of the system.

Description

technical field [0001] The invention belongs to the field of new energy technology and relates to regional energy Internet, in particular to a regional energy Internet multi-source coordinated optimization operation strategy considering time-of-use electricity price. Background technique [0002] With changes in the social environment such as energy security, climate crisis, and environmental protection, countries have undergone real-time energy structure changes and energy consumption changes. Energy Internet is a comprehensive use of various advanced power electronics technology, information communication technology and intelligent management technology to interconnect power network, oil network, natural gas network, transportation network and other energy sources to realize the two-way energy exchange and sharing of energy. complex system. Its construction and development are important changes in the field of energy technology, aiming to improve energy utilization effici...
