A multi-objective fuzzy optimization method for integrated energy system

Abstract

The invention provides a multi-objective fuzzy optimization method for an integrated energy system considering efficiency. First, various energy component unit models are established on the basis of obtaining the structure of the integrated energy system, energy component units, and various load information; Analysis models, including output and input flow analysis models. At the same time, set operating constraints, including capacity constraints, climbing constraints, and energy balance constraints; secondly, establish single-objective optimization models, including economical optimization models, comprehensive efficiency optimization models, and environmental protection optimization models. On this basis, a multi-objective fuzzy optimization model is established. Finally, the model program is written based on the LINGO18.0 software platform and the global solver is called to solve the built multi-objective fuzzy optimization model. The effectiveness of the present invention in optimizing the operation of the integrated energy system is verified through case analysis, and it is of guiding significance for the multi-scenario optimized operation of the integrated energy system.

Description

technical field [0001] The present invention relates to integrated energy systems, in particular to a consideration Multi-objective fuzzy optimization method for efficient integrated energy systems. Background technique [0002] Energy is the basis and important guarantee for human survival and the lifeline of the national economy. How to ensure sustainable energy supply while reducing environmental pollution is the focus of common concern in today's society. For a long time, the traditional regional energy system lacks unified and optimized operation of energy consumption, and there are common problems such as energy waste, environmental pollution, independent energy supply, and low level of energy cascade utilization, which greatly affects the operating efficiency and economic and environmental benefits of the system. In this context, the concept of an integrated energy system emerged as the times require. The integrated energy system integrates public cooling, heating, ...
