Abstract

The invention discloses a park comprehensive energy optimization method and device based on an ADMM alternating direction multiplier method, and the method comprises the steps: obtaining the declaration information of a participant, and displaying the real-time demands and output information on a public interface; and according to the declaration information, adopting an ADMM alternating directionmultiplier method to carry out pre-optimization processing, decomposing the electric power and energy system into two optimization sub-problems of the electric power system and the natural gas system, and generating optimization parameters and an optimization result by taking the minimum operating cost of the energy system of the whole park as a target, sending the optimization parameters and theoptimization result to each enterprise in the park; performing safety check according to the optimization parameters; and if the emergency situation occurs, sending an emergency announcement according to the emergency situation, and carrying out emergency optimization processing. According to the invention, the problems of non-transparent information, complex model and the like in the centralizedand unified optimization method of the energy system can be solved, and the collaborative optimization of the comprehensive energy system in the park is realized through the interaction of a small amount of information between the power system and the natural gas system.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a park comprehensive energy optimization method and device based on the ADMM alternating direction multiplier method. Background technique [0002] With the improvement of environmental protection requirements and the development of clean energy technology, with the background of comprehensive energy system, the research on integrating natural gas, electric energy and other energy sources in the region to realize the coordinated planning and optimal operation of different energy sources is in the ascendant. [0003] In the optimal dispatching of the traditional electric power-natural gas system, the dispatching of the electric power system and the natural gas system are not consistent, but have their own unique ways, often ignoring the interaction and coupling relationship between the electric power system and the natural gas system, which may lead to an overly idea...
