Optimization configuration of regional integrated energy system based on standard module

摘要

An optimal design of a regional integrated energy system (RIES) configuration is necessary to realize the efficient use of various energy resources as well to improve the energy efficiency and economic benefits of the integrated energy system (IES). Practical integrated energy projects often have problems with unreasonable capacity configuration which results in poor system economics and inoperability. In the current research on the capacity allocation of RIESs, the type of energy system is singular and the coupling relationship between various parts of the system is rarely considered. This results in a lack of theoretical guidance and calculation tools for the optimal designing of future RIESs. This study researches the optimization of the capacity allocation of IES based on typical residential area modules and typical commercial modules built on actual regional plots. TRNSYS is selected to simulate energy consumption, and Genopt has been selected to build the optimization system platform, couple the regional load demand, configure multi-energy system, and optimize the real-time results of the calculation. With aim to achieve the lowest life cycle cost of the IES, this research analyzes the optimized configuration of IESs including the composite cold and heat source system. This study establishes a fast and efficient IES optimal capacity ratio calculation model, which is 7.55% different from the actual energy consumption of the project. This study also provides theoretical methods and calculation tools for the ongoing research on the optimal design of RIESs, including composite cold and heat source systems and effectively improving system economics.
