Electricity-hydrogen complementary park multi-building energy supply system and coordinated scheduling method thereof

Abstract

The invention relates to an electricity-hydrogen complementary park multi-building energy supply system and a coordinated scheduling method thereof, and the method comprises the steps: analyzing the operation mechanisms of energy flow, information flow and control flow in a park according to an actual park project, carrying out the classification according to the reliability and economical efficiency requirements of different buildings, and building an electricity-hydrogen complementary park multi-building energy supply system containing hydrogen energy storage; energy and loads in a power supply system are modeled respectively and applied to a scheduling model of an electricity-hydrogen complementary park multi-building energy supply system; an interaction mechanism of interconnection of multiple buildings in the park multi-building energy supply system is established, and under the support of a multi-agent reinforcement learning algorithm, energy supply scheduling is performed in real time according to historical data of the buildings in a mode of ''offline centralized learning and online distributed execution''. The operation structure of the carbon neutralization park is constructed by utilizing the electricity-hydrogen complementation characteristic and the electric energy sharing among the buildings, and under the support of a multi-agent reinforcement learning algorithm, the overall optimization is realized in the self-optimization process of each building, and the selection of dimensionality disasters and suboptimal actions is avoided.

Description

technical field [0001] The invention relates to an energy management technology, in particular to a park multi-building energy supply system and a coordinated scheduling method thereof considering the complementarity of electricity and hydrogen under the double carbon target. Background technique [0002] With the continuous innovation and development of renewable energy generation technology and the sharp drop in cost, its penetration rate is also gradually increasing, which may bring intermittent and reliability problems to the grid, so new solutions are needed to flexibly deploy resources in the system. Improving energy utilization through the conversion and storage of multiple energy sources is the current mainstream research direction, and the role of energy storage is particularly important. However, traditional electric energy storage methods, such as batteries and supercapacitors, have the risk of spontaneous combustion, and are not suitable for installation in plac...
