Problems solved by technology

Although the distributed method takes into account both privacy requirements and real-time requirements, in the absence of supervision and approval mode, some subjects tend to take their own interests into consideration, resulting in the optimization results deviating from the overall optimization goal, which is not conducive to the economy of the entire system operation , stability, safety and reliability

Embodiment Construction

[0043] Such as figure 1 As shown, a county-level electrical-gas interconnection system optimal dispatching method under a two-layer collaborative architecture includes the following steps:

[0044] (1) Considering the independence of scheduling and the privacy of some data, construct a two-layer coordinated county-level electric-gas interconnection system optimal scheduling framework. Diesel generators, combined heat and power units, etc., while the top-level monitoring center is responsible for monitoring important parameters or indicators, including grid voltage quality indicators, peak-shaving and valley-filling indicators, etc., allowing autonomous decision-making under the condition of ensuring safety. When the result deviates from the global optimality, a coordinated modification strategy is issued to ensure the safe operation of the system;

[0045] (2) Each distributed energy entity at the bottom layer corresponds to deploy a distributed soft controller, and reasonabl...

Abstract

The invention discloses a county-level electricity-gas interconnection system optimal scheduling method under a double-layer collaborative architecture, and solves the privacy problem and the real-time problem generated when a distributed energy main body participates in county-level electricity-gas interconnection optimal scheduling. Through regulation and approval, the distributed autonomous optimization scheduling not only considers the benefits of the energy main body participating in scheduling, but also meets the global optimality requirement, and ensures the safe and stable operation of the system.

Description

technical field [0001] The present invention relates to the technical field of comprehensive energy Internet, in particular to a method for optimal dispatching of county-level electrical-gas interconnection systems under a two-layer collaborative architecture. Background technique [0002] Energy is not only the lifeblood of the national economy, but also the basis for human survival and development. At present, traditional fossil fuels, including coal and petroleum, still occupy a relatively large proportion of total energy consumption. However, with the massive increase in energy demand, the contradiction between energy with high pollution characteristics and environmental problems has become increasingly prominent, and it is urgent to vigorously develop clean energy to improve the energy structure. In the context of the gradual liberalization of the energy market, the energy Internet system has become a new form of energy industry development, which is expected to solve ...
