Abstract

The invention discloses a comprehensive energy microgrid distributed economic dispatching optimization method and system, and the method comprises the steps: analyzing the working characteristics of a hydrogen energy storage system, and obtaining the energy flow paths of a power energy flow, a natural gas energy flow and a hydrogen energy flow; according to the working characteristics of the hydrogen energy storage system, establishing an economic dispatching optimization model with the purpose of minimizing the operation cost of the integrated energy microgrid; establishing constraint conditions of the economic dispatching optimization model, wherein the constraint conditions comprise hydrogen energy storage system constraint, power system constraint, natural gas system constraint and coupling element constraint; according to the economic dispatching optimization model and the constraint condition, constructing a distributed solving method based on an alternating direction multiplier method, obtaining an optimal solution meeting the convergence condition after the power system economic dispatching optimization sub-problem and the natural gas-hydrogen economic dispatching optimization sub-problem are subjected to alternating iteration solving, and optimizing economic dispatching. Global optimization can be realized under the condition of limited information interaction.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to an integrated energy microgrid distributed economic scheduling optimization method and system. Background technique [0002] The strategic goals of carbon peaking and carbon neutrality conform to the trend of global low-carbon development. As a main component of the Energy Internet, the Integrated Energy System (IES) has become a key link in realizing energy conservation and emission reduction. IES can break the existing inherent mode of independent planning and operation of individual energy subsystems, thereby ensuring the economical, efficient, and coordinated operation of multi-energy systems. Therefore, the economic dispatch optimization of IES is one of the current research hotspots. [0003] In the Integrated Electricity-Gas System (IEGS), there are a large number of coupling relationships between gas generators or power-to-gas (P2G) equipment. IEGS mainly considers the ...
