Abstract

The invention discloses a comprehensive energy layered optimal operation method and system of a hydrogen-containing utilization system. The method comprises the following steps: constructing a comprehensive energy operation system containing a hydrogen utilization system; the comprehensive energy operation system adopts a layered distributed architecture and is divided into a subsystem coordination control system layer and an overall coordination control system layer, and the subsystem coordination control system layer and the overall coordination control system layer operate in a mutual coordination mode. The subsystem coordination control system comprises a photovoltaic system operation unit, an electrochemical energy storage system operation unit, a hydrogen production system operation unit and a fuel cell system operation unit; the overall coordination control system comprises a publishing and receiving module, a scheduling setting module, an optimal scheduling module, a coordination operation control module and an overall coordination database; the optimal scheduling module comprises a whole-station economic operation module and a peak load shifting module; the overall coordination control system takes the optimal comprehensive energy economy as a target, comprehensively considers the real-time output condition sent by each subsystem, preferentially consumes new energy locally for power generation, and realizes layered optimal operation of the comprehensive energy station.

Description

technical field [0001] The invention belongs to the technical field of operation optimization of regional comprehensive energy systems, and in particular relates to a method and system for comprehensive energy layered optimization operation of a hydrogen-containing utilization system. Background technique [0002] At present, the increasing shortage of conventional fossil energy and the increasing environmental pollution have brought enormous pressure to the power system, especially in remote areas such as plateaus, border defenses and islands, which are far away from the power grid, lack coal and water resources, and suffer from bad weather, inconvenient transportation, and poor living conditions. The conditions are difficult, and it is difficult to solve the daily electricity consumption problem of residents through power grid transmission or the establishment of thermal power stations in the local area. Renewable energy power generation, especially wind power generation a...
