Problems solved by technology

[0003] However, with the large-scale access of wind power and other uncertain power generation resources, it is difficult for CHP to supply energy by heat or electricity to meet the requirements of multi-energy coupling systems for the consumption of renewable energy (RES) under the new situation. At the same time, the problem of peak regulation in the power system has become increasingly prominent
In order to cope with the inherent uncertainty and intermittency of wind power output, the power system needs to reserve a large number of power generation reserves to meet the load demand, which not only reduces the power generation efficiency of conventional generator sets, but also inevitably increases the dispatching cost of the power system

Abstract

The invention discloses a scheduling method of a multi-energy coupling system. The method is executed in computing equipment and comprises the following steps of: modeling uncertain factors of the multi-energy coupling system to determine a probability density function of each uncertain factor; generating a plurality of discrete scenes according to the probability density function, and reducing the plurality of discrete scenes to eliminate redundant scenes; and based on the reduced discrete scenes, under a set operation constraint condition, determining an optimal scheduling scheme for minimizing the operation cost of the multi-energy coupling system. The invention also discloses corresponding computing equipment.

Description

technical field [0001] The invention relates to the technical field of multi-energy system scheduling, in particular to a stochastic programming method for a multi-energy system oriented to the synergy between renewable energy and demand response. Background technique [0002] With the rapid development of the economy, climate and environmental issues have become increasingly prominent, prompting the current energy system to gradually develop towards a low-carbon and sustainable direction. The multi-energy coupling system (MES) based on combined heat and power (CHP) technology can recover waste heat in the power generation process through CHP, saving the primary energy required for heating, improving the overall energy efficiency and greatly reducing greenhouse gas emissions. It provides an important solution for realizing regional energy supply. To this end, cogeneration has been steadily increasing its share of electricity generation in many countries. [0003] However, ...
