随着可再生能源(RES)的日益普及,传统综合能源系统正在向低碳综合能源系统(LCIES)转变。然而,相比于传统电能,并没有明确考虑RES发电不确定性的电能质量和成本模型,这使得实现LCIES的低成本、高效率运行变得更为复杂。为了应对这一挑战,提出了一种基于熵理论的分析方法来量化RES发电的不确定性成本和效率。首先,提出了一个等效燃料成本模型。该模型建立了能量层和信息层的联系,等效量化了消除RES不确定性的信息成本。在此基础上,利用熵理论建立了信息能量质量系数来分析RES的能量质量。最后,提出了一种基于神经动力学的全分布式优化算法,对LCIES内的成本和能源效率进行多目标优化。仿真结果验证了所提方法在提升系统能效与经济性方面的优越性。
With the increasing popularity of renewable energy sources (RESs)
traditional integrated energy systems are transforming into low-carbon integrated energy systems (LCIES). However
compared with traditional electricity
there is no clear model for the quality and cost of electricity that explicitly considers the uncertainty of RES generation
which makes the low-cost and high-efficiency operation of LCIES more complex. To address this challenge
an analysis method based on the entropy theory is proposed to quantify the uncertainty cost and efficiency of RES generation. Firstly
an equivalent fuel cost model is proposed
which establishes the connection between the energy layer and the information layer
and equivalently quantifies the information cost of eliminating the uncertainty of RES. On this basis
the information energy quality coefficient is established by using the entropy theory to analyze the energy quality of RES. Finally
a fully distributed optimization algorithm based on neural dynamics is proposed to perform multi-objective optimization of cost and energy efficiency within LCIES. The simulation results verify the superiority of the proposed method in improving the energy efficiency and economy of the system.
