摘要:

为建立典型终端型多能互补系统模型,了解不同优化目标下系统最优配置的特点和性能影响因素,提出一种集成太阳能、风能、天然气的终端型多能互补系统,并基于母线式结构对系统能流特性进行分析,建立系统设计运行一体化优化模型。研究了优化目标和能源价格对系统最优配置和性能的影响,阐明了微燃机、内燃机、吸收式制冷机等典型设备的适用场景,以及灵活性电源、储能装置对风光消纳的促进作用,验证了系统环保与化石燃料节约水平的一致性,以及当前考虑的技术经济水平下经济性与环保水平的反向关系。结果发现,存在最适宜的天然气价格确保下调压力适当,并明确了电价峰谷差大小对系统性能的影响,研究结果可为系统集成优化设计和能源价格政策制定提供参考。

Abstract:

In order to establish a typical terminal multi-energy complementary system and know the characteristics of different optimal configurations and influence factors of its performance under different optimization objectives, this paper proposed a terminal multi-energy complementary system that integrates solar energy, wind energy and natural gas. The energy flow characteristics were analyzed based on the bus-bar structure, and an integrated optimization model for the design and operation of the system was established accordingly. Furthermore, the effects of optimization objectives and energy prices on the optimal configuration and performance of the system were studied, and the applicable scenarios of typical equipment such as micro-gas turbine, internal combustion engine and absorption chiller were illustrated, as well as the promoting effects of flexible power supply and energy storage device on the consumption of photovoltaic and wind power. The relationship between annual CO2 emission reduction ratio and fossil fuel saving ratio of the system is consistent, and that between annual cost saving ratio and CO2 emission reduction ratio is contrary under current technical and economic conditions. The most suitable natural gas price to ensure the applicable downward pressure exists and the effect of peak-valley difference of electricity price on system performance is clarified. The results can provide reference for system integration optimization design and energy price policy formulation.

Key words: multi-energy complementary, bus-bar structure, optimal configuration, performance analysis, energy price analysis
