Abstract

The invention relates to the technical field of energy system optimization scheduling, in particular to a distributed optimization method, device and equipment for an integrated energy system and a storage medium. Establishing a distributed optimization scheduling model of a plurality of interconnected energy hubs; based on a homomorphic encryption algorithm and an alternating direction multiplier method, optimizing the distributed optimization scheduling model of the plurality of interconnected energy hubs to obtain an optimization result; and according to an optimization result and an interaction relationship between the information layer and the physical layer, controlling the output of each capacity unit in the region of the integrated energy system and the operation state of each node of the multi-energy network to reach the optimal state, and sharing the optimal energy among multiple regions of the integrated energy system. Therefore, the problem of privacy leakage in the information interaction process between the interconnected energy hubs is solved, the convergence of the proposed algorithm is guaranteed, multi-energy optimal energy sharing is realized, and the method has good application value.

Description

technical field [0001] The present application relates to the technical field of energy system optimization and scheduling, and in particular, to a distributed optimization method, device, device and storage medium for an integrated energy system. Background technique [0002] To address the challenges posed by global climate change, most countries have reached a consensus on achieving carbon neutrality by the middle of this century. In recent years, new energy represented by wind power and photovoltaics has developed rapidly. According to statistics, the national installed capacity of power generation in 2021 will be about 2.38 billion kilowatts, a year-on-year increase of 7.9%. Among them, the installed capacity of wind power is about 330 million kilowatts, a year-on-year increase of 16.6%; the installed capacity of solar power generation is about 310 million kilowatts, a year-on-year increase of 20.9%. However, my country's current energy structure is still dominated by ...
